Third, there are severe limits to developing and propagating genetically modified crops in many countries, especially in Europe. StDMR6-2 and StDMR6-1 transcripts are approximately 80% identical at the nucleotide level. Genome Editing: Targeting Susceptibility Genes for Plant - PubMed Figure1 Growth phenotypes of Stdmr6-1 and Stdmr6-2 mutant lines. The journal serves as an international platform for researchers working on plant, animal and microbial proteomics. The .gov means its official. A plant's place in history can predict susceptibility to pathogens Date: March 8, 2021 Source: American Phytopathological Society Summary: Found around the world, powdery mildew is a fungal. Ecological adaptations influence the susceptibility of plants - Nature Plant Microbe Interact. 30, 179189 (2017). This gene is a negative regulator of the active SA pool; thus, it is important for the SA-dependent plant immune system. PhD student Susceptibility genes in tomato | EURAXESS Genome editing in potato via CRISPR-Cas9 ribonucleoprotein delivery. In this review, we refer to genes required for susceptibility as disease susceptibility genes (S-genes), such as genes coding for effector targets that function as negative defense regulators or susceptibility factor (Fig. Visser, R.G.F. The mutant was isolated as a constitutive expressor of the -glucuronidase transgene under the control of the CEVI-1 gene promoter, which shows SA-dependent induction after viral infection in susceptible tomato varieties. FOIA Accessibility Sci. Yin, K. & Qiu, J. L. Genome editing for plant disease resistance: Applications and perspectives. Identification and accurate mapping of new resistance genes are essential for gene pyramiding in wheat breeding. Plants mutated in StDND1 showed pleiotropic effects, whereas StDMR6-1 and StCHL1 mutated plants did not exhibit any growth phenotype, making them good candidates for further agricultural studies. Furthermore, transformation of Col-0 with cDNA corresponding to RPW8.1 or RPW8.2 under the control of the 35S promoter of Cauliflower mosaic virus was sufficient to confer resistance similar to that seen in the Ms-0 accession. (, Xiao, S., Ellwood, S., Findlay, K., Oliver, R.P., and Turner, J.G. Additionally, larger CRISPR/Cas mediated deletions may easily be scored by PCR with primers specific to or flaking the target region22,23. After PCR screening of 169 putative HDS shoots, we did not obtain any tetra-allelic mutant lines (Table 2). Engineering canker-resistant plants through CRISPR/Cas9-targeted editing of the susceptibility gene CsLOB1 promoter in citrus. Bookshelf Priming defense by transiently suppressing plant susceptibility genes Wheat and barley are two of the most severely affected crops, but many other vegetable, fruit, and ornamental crops and trees are affected similarly. 17, 11191129 (2019). The triphosphate tunnel metalloenzymes (TTMs) hydrolyse organophosphate substrates39. (2022) Mallick et al. 5th ed. (2001)determined that the RPW8 locus, which mapped to chromosome 3, is a key locus for broad-spectrum resistance to powdery mildew (and possibly is the same locus as those that elsewhere were named RPW7, RPW10, and RPW13). Interestingly, up-regulation of trehalose-6-phosphatase gene and low affinity cation transporter in IR BB67 suggest that IRBB67 maintained a certain homeostasis under high temperature which may have enhanced its resistance. As in the examples given in Laquitaine L., Goms E., Franois J., Marchive C., Pascal S., Hamdi S., et al.. (2006). Zaidi, S. S. E. A., Mukhtar, M. S. & Mansoor, S. Genome Editing: Targeting Susceptibility Genes For Plant Disease Resistance. No RPW8 alleles were detected by DNA gel blot hybridization in the Col-0 accession, which is extremely susceptible to powdery mildew, and sequence analysis of the Col-0 region corresponding to Ms-0 RPW8 showed a single gene predicted to encode proteins having only 50 to 52% similarity to the Ms-0 RPW8 proteins. Plants | Free Full-Text | Fine Mapping of Stripe-Rust-Resistance Gene Most potato cultivars used commercially are tetraploid and rarely produce berries21. antiviral defense; gene silencing; host factors; virus accumulation; virus movement; virus resistance; virus susceptibility genes. Transcription activator-like effectors (TALEs) produced by plant pathogenic bacteria mainly belonging to the genus Xanthomonas cause plant diseases through activation of host susceptibility genes in plant cell nuclei. However, there are three major obstacles to achieving this goal: First, although loss-of-function mutations of S-genes could be generated via various approaches, such as using natural alleles from genetic resources, stable RNAi, and newly emerging gene editing techniques, these approaches are technically challenging in many other ornamental crops due to their polyploid genomes and the lack of efficient transformation techniques. Rodriguez-Pea R, Mounadi KE, Garcia-Ruiz H. Viruses. 1F and Table 3) but also did not differ in over-all growth phenotype compared with the wild type (Fig. 21, 8999 (2012). Originally, StCHL1 was found through microarray analysis of brassinosteroid responsive marker genes in potatoes. Recently, a wheat mlo mutant was shown to be susceptible to the hemibiotrophic fungal pathogen Magnaporthe oryzae, whereas it was still resistant to the obligate biotrophic fungus Blumeria graminis11. Potato Res. Plant virus infection progression, movement,, Plant virus infection progression, movement, and symptoms caused by virus infection. Plants | Free Full-Text | Involvement of miRNAs in Metabolic Herbicide 1 for the lines that were subsequently screened for late blight resistance and growth phenotypes. On the most fundamental level, susceptibility helps communicate the risk of developing a disease. An Era of CRISPR/ Cas9 Mediated Plant Genome Editing. Kieu, N.P., Lenman, M. & Andreasson, E. Potato as a Model for Field Trials with Modified Gene Functions in Research and Translational Experiments in Solanum Tuberosum: Methods and Protocols. Xiao et al. Another attractive feature of eliciting priming for plant protection is that it avoids the use of environmentally problematic fungicides; the use of these products can also lead to the appearance of fungal strains resistant to these fungicides. oryzae ( Xoo ) implies substantial yield loss to rice. Specific TALes, referred to as major TALes, transcriptionally activate the corresponding SWEET genes in rice during infection to promote the disease in a gene-for-gene susceptibility manner [ 42 ]. Based on biological function, S-genes have been divided into three groups12,13. Consider Determinants of Virus Variation, Evolution, and Host Adaptation. government site. Le Fevre, R., OBoyle, B., Moscou, M. J. The involvement of each homolog of an S-gene family demands a case-by-case assessment of their usefulness for resistance in each plant species. Recent research suggested various natural or synthetic agents could be used to downregulate multiple S-genes simultaneously. For our screen of edited potato plants, we chose to use PCR with gene-specific primers, spanning both gRNA targets, followed by gel electrophoresis analysis, as a simple, inexpensive, and rapid method for detecting deletions in the target gene. Article Genetics, genomics and breeding in Rosa species. Deng X., Elomaa P., Nguyen C. X., Hytnen T., Valkonen J. P., Teeri T. H. (2012). Chin, K., Defalco, T. A., Moeder, W. & Yoshioka, K. The arabidopsis cyclic nucleotide-gated ion channels AtCNGC2 and AtCNGC4 work in the same signaling pathway to regulate pathogen defense and floral transition. Sci. S-genes involved in susceptibility to different types of pathogens have been found in many different plant species17,34. One typical S-gene is MLO (Mildew Locus O), which was originally characterized in spring barley in the 1940s and later used in European plant breeding programs in the 1970s. NCI Dictionary of Genetics Terms - National Cancer Institute Clipboard, Search History, and several other advanced features are temporarily unavailable. 2018;26:47-54. doi: 10.21775/cimb.026.047.

Susceptibility Genes 101: How to Be a Good Host New research with a focus on loss of function mutations has led to the identification of disease susceptibility ( S) genes in plants. (C) Plant height of wild type and Stdmr6-2 mutant lines. Figure1 Agrotechnology 07, 25 (2018). Interestingly, the mutant is more susceptible than wild-type plants to virulent strains of P. syringae and P. parasitica and is compromised in the development of SAR, but it shows normal SA metabolism and activation of PR genes. Three other accessions that were moderately susceptible to powdery mildew, Ler, Nd-0, and Ws-0, contain RPW8 alleles that are different from those of Ms-0, and they are predicted to encode proteins with 90 to 95% similarity to the Ms-0 proteins. sharing sensitive information, make sure youre on a federal Five tetra-allelic mutants in two potato backgrounds (Dsire and King Edward) showed the same infection lesion size and percentage of infected leaves as that of the wild type. We also concluded that the pDIRECT_22C vector and the applied deletion screening system expressing two gRNAs for fast PCR mediated screening of full or partial allele knockout was highly efficient and applicable in potatoes. GSHR, a web-based platform provides gene set-level analyses of hormone responses in arabidopsis. Nakayasu, M. et al. For each experiment, nine fully developed leaves from 5-week-old plants from each line were used for detached-leaf assays (DLAs). 175, 473485 (2017). Nucl. Thus, the establishment of infection is genetically determined by the availability of host factors necessary for virus replication and movement and by the balance between plant defense and viral suppression of defense responses. M.L. DMR6 proteins belong to the 2-oxoglutarate (2OG)-Fe (II) oxygenase family. Spermine is a potent plant defense activator against gray mold disease on. Engineering crop resistance by manipulating disease susceptibility genes A transposable element insertion in the susceptibility gene YB, ZZ, and XL conceived and wrote the paper.

Here, such susceptibility ( S) genes are reviewed with a focus on the mechanisms underlying loss of compatibility. made the modelling. Plant Physiol. In A. thaliana, the Athds was mutagenized with ethyl methanesulfonate (EMS) and influenced chloroplast development and increased resistance to Pseudomonas syringe47. The tetra-allelic Stdnd1 mutated potato not only exhibited a late blight resistance phenotype (Fig. PubMed . No mutant line showed any altered phenotype (growth, morphology, or pathogen resistance) when compared with wild-type plants (Figs. 44, 155166 (2005). Resistance to fungal and bacterial pathogens often involves the induction of the hypersensitive response (HR) and the development of systemic acquired resistance (SAR) via the salicylic acid (SA) signaling pathway.

The tetra-allelic Stdnd1 mutant lines, except for the strong resistance phenotype, also showed reduced growth, long and thin stems, as well as necrosis of all leaves (Figure S4A). Plants respond to viral infection by several mechanisms, including innate immunity, autophagy, and gene silencing, that . Susceptibility Genes to Plant Viruses - ResearchGate This site needs JavaScript to work properly. Our results demonstrated that StDMR6-1 and StCHL1 are promising S-gene candidates for generating increased late blight resistance in potatoes. Plant Sci. Transcriptome responses of the aphid vector Myzus persicae are shaped M . The site is secure. Balmer A., Pastor V., Glauser G., Mauch-Mani B. Turnbull, D. et al. hordei in barley is controlled by recessive, loss-of-function mutations in a single gene, Mlo (Jrgensen, 1992; Buschges et al., 1997). However, potato crops are affected by pests and many diseases, such as late blight, early blight, bacterial wilt, potato blacklegs, Colorado potato beetles, and cyst nematodes (https://cipotato.org/crops/potato/potato-pests-diseases/). For transformation, 1mL of the Agrobacterium suspension (OD 1.92.0) was pipetted onto dissected leaf explants that were placed on the co-cultivation media. 1D) as observed from the results of the earlier RNAi study but also showed pleiotropic phenotypes, such as line DND 583 (Fig. The . 2022 Sep 23;13:997888. doi: 10.3389/fpls.2022.997888. Wu Z., Liang J., Wang C., Zhao X., Zhong X., Cao X., et al.. (2018). Nucl. Wheat production is often affected by different types of rust diseases, in which stripe rust is triggered by a fungal pathogen, Puccinia striiformis f. sp. (B) Wild type Dsire and hds mutant lines at 2-weeks-old stage. The robustness of new breeding techniques is exemplified by CRISPR-CRISPR-associated protein 9 (Cas9) in susceptibility (S) gene targeting. The https:// ensures that you are connecting to the We also calculated the percentage of successful infection. Functional groups of host and viral factors based on their role in virus infection. By applying two guide RNAs, targeted deletions in the gene of interest may be generated22,23. Selected mutant lines were propagated by cutting node segments and culturing them in9025mm Petri dishes containing 25mL MS10 medium. , the functional S-genes and their suppressor agents can be identified through the bioinformatic, reverse genetic and phytopathological approaches. In tomatoes, the CRISPR-Cas9 mediated mutation of the StDMR6-1 ortholog SlDMR6-1 showed increased resistance to P. capsici and P. syringae pv. government site. Triphosphate tunnel metalloenzyme function in senescence highlights a biological diversification of this protein superfamily. Rev. Functional knockouts of StDND1, StCHL1, and DMG400000582 (StDMR6-1) generated potatoes with increased resistance against late blight. Mol. 17, 235 (2017). By contrast, Erysiphe produces fungal mycelia only on the leaf surface. Zhang, L. et al. Designer TAL Effectors Induce Disease Susceptibility and Resistance to 9, 385402 (2008). Preharvest treatments with chitosan and other alternatives to conventional fungicides to control postharvest decay of strawberry. In potatoes, knockdown of StDMR6 by RNAi increased late blight resistance without any documented effect on growth phenotype12. Bowling, S.A., Clarke, J.D., Liu, Y., Klessig, D.F., and Dong, X. In addition to BTH, the analysis of the continuously generated Omics data allows us to high-throughput screen for novel suppressor agents for the regulation of S-gene and modulation of plant resistance. Plants respond to viral infection by several mechanisms, including innate immunity, autophagy, and gene silencing, that viruses must evade or suppress. In the present study, in agreement with this observation, some calli turned white and did not develop into seedlings. The first group includes genes required for early pathogen infestation or to promote pathogen infestation. On the one hand, unique differences in DNA can increase or decrease our risk of developing a disease. Keywords: The resistance mediated by mutant alleles of S-genes have been reported in various plant species, and has been successfully applied to breeding for many years. This was somewhat unexpected because the mutation of orthologous MLO genes is effective in many plant and pathogen species36,37, including the hemibiotrophic P. palmivora. Resistance and susceptibility are opposite sides of the same coin, and research on disease resistance cannot be conducted without reference to susceptibility. Careers. Many bacterial species use effector proteins to target S genes, resulting in effector-triggered susceptibility. (. Knockdown of StDMR6 in potatoes by RNAi showed an unclear resistance phenotype, with only six out of 12 transformed plants showing lower transcript levels of DMR6 and four plants showed a resistance phenotype, whereas eight plants showed susceptibility to Phytophthora infestans12. Frontiers | Identification of Candidate Susceptibility Genes to Proviral factors condition susceptibility to viruses by participating in processes essential to the virus. Plant disease resistance - Wikipedia Google Scholar. The edr1 mutation in Arabidopsis defines another locus that confers recessive broad-spectrum resistance to powdery mildew. Chen R, Tu Z, He C, Nie X, Li K, Fei S, Song B, Nie B, Xie C. Hortic Res. https://doi.org/10.1104/pp.17.00695 (2017). Appiano, M. et al. Keywords: 2016). as such, we suggest that two key aspects of host-parasite biology will need more consideration as we move forward in the genomics era: first, that our understanding of the genetics of susceptibility will depend on the number of parasite genotypes included in association studies; and second, that the expectation of epistasis may not be appropriate For this reason, R genes have been used in conventional resistance breeding programs for decades . However, the plants were smaller and showed early senescence and necrotic spots on leaves of older plants. 2020;107:37-86. doi: 10.1016/bs.aivir.2020.04.002. S genes can be identified and precisely mutated through new genome engineering tools. Priming defense by chemically suppressing plant S-genes in ornamental crops, using gray mold disease (caused by Botrytis cinerea) as an example. Susceptibility reversed: modified plant susceptibility genes for resistance to bacteria, Plant cellulose synthesis: CESA proteins crossing kingdoms. The YrJ22 gene is a dominant stripe-rust-resistance gene located at the distal end of chromosome 2AL, which was identified in a leading Chinese-wheat variety, Jimai 22, showing high resistance to CYR32, a prevalent race of Puccinia striiformis tritici (Pst) in China.

Plants. Hence, altering a plant gene that critically facilitates compatibility could provide a more broad-spectrum and durable type of resistance. It is important to note that both the race-specific resistance conferred by Mla genes and the broad-spectrum resistance conferred by Mlo appear to operate via the control of cell death. Multiple phytohormone signals control the transcriptional response to soybean aphid infestation in susceptible and resistant soybean plants. Engelhardt, S., Stam, R. & Hckelhoven, R. Good riddance? Pavan S., Jacobsen E., Visser R. G., Bai Y. A detached petal disc assay and virus-induced gene silencing facilitate the study of botrytis cinerea resistance in rose flowers, Genome-wide transcriptome analysis and identification of benzothiadiazole-induced genes and pathways potentially associated with defense response in banana. This makes it cost and labour effective, as well as giving it the ability to produce transgene-free offspring14,16. Results were recorded by measuring the infection size of each leaflet at 7 d post-inoculation (dpi). Adv Virus Res. will also be available for a limited time. For instance, the report has identified 19 MLO genes in rose. Resistance of Plants to Parasitic Nematodes and Its Application in J. susceptibility gene A gene that increases a person's likelihood of contracting a heritable illness. However, it is worth remembering that semantics often makes a difference (i.e., it matters what we choose to name things), and it may prove enlightening to examine the susceptibility side of the plant disease coin from the perspective of plant genetics. For perennial woody plants, it is important to establish an efficient transformation method to facilitate gene functional studies and protein subcellular localization assays. As this is apparently not the case, S genes should have important functions apart from being involved in pathogenesis. ARG2-mediated resistance is accompanied by higher expression of defense and secondary metabolite genes at early stages of infection, and anthocyanin and zeatin metabolisms are upregulated in resistant plants. Moon KB, Park SJ, Park JS, Lee HJ, Shin SY, Lee SM, Choi GJ, Kim SG, Cho HS, Jeon JH, Kim YS, Park YI, Kim HS. However, classical breeding by recurrent selection is time-consuming as well as complicated in tetraploid potatoes. Careers, Edited by: Yi Han, Anhui Agricultural University, China, Reviewed by: Xi Luo, University of Maryland, College Park, United States; Xi Cheng, Beijing Academy of Agricultural and Forestry Sciences, China, This article was submitted to Plant Bioinformatics, a section of the journal Frontiers in Plant Science. Plant J. It is caused by the oomycete pathogen Phytophthora infestans, which can infect the leaves, stems, and tubers of potato plants. Nekrasov V., Wang C., Win J., Lanz C., Weigel D., Kamoun S. (2017). Haeussler, M. et al. Archives of Proteomics and Bioinformatics For example, the recessive mutation of CESA3, one of the cellulose synthesis-related genes, showed an increased level of JA, abscisic acid (ABA) and ethylene (ET), resulting in enhanced resistance to several pathogens (Ellis etal., 2002; Kumar and Turner, 2015). Once the host plant enters the priming phase, only mild changes occur at the transcriptional and/or epigenetic level without the dramatic induction of many defense genes. Here, S-gene candidates were selected based on the following criteria: pathogen resistance phenotype, being either a single gene or belonging to a small confined gene family in potatoes, each S-gene concerning other candidates should have a different function, and if possible, function in different pathways (see Table 1). Loss of susceptibility as a novel breeding strategy for durable and broad-spectrum resistance. Introduction Gruner, K. et al. Research within the last 10 years has greatly increased our knowledge of the genetic mechanisms of plant disease resistance. For the majority of plant diseases, the genetics of susceptibility are less tangible. https://doi.org/10.1016/j.tibtech.2018.04.005 (2018). Step 3). Normally, several fungicide sprays are applied during a cropping season to control late blight disease4. Cell wall analysis using Fourier transform infrared spectroscopy suggested that the cell walls of the mutant are enriched in pectin, supporting the idea that PMR6 is a pectin-degrading enzyme. Kim, D. S. & Hwang, B. K. The pepper MLO gene, CaMLO2, is involved in the susceptibility cell-death response and bacterial and oomycete proliferation. The identified functional S-genes ( Regeneration and Transformation of Potato by Agrobacterium Tumefaciens. The project is further supported by the Construction of Beijing Science and Technology Innovation and Service Capacity in Top Subjects (CEFF-PXM2019_014207_000032). The susceptibility genes ( S -genes) refer to the plant genes required by phytopathogens to facilitate their compatible interaction with hosts ( Pavan et al., 2010; Koseoglou et al., 2021 ). With a function as a Phytophthora effector target and transcription factor, and being involved in brassinosteroid hormone signalling and immune response to P. infestans50, StCHL1 has clear potential as an useful S-gene; possibly when combined with other S- or R-factors to improve pathogen resistance.
