Root and foot diseases severely impede grain legume cultivation worldwide. Breeding lines with resistance against individual pathogens exist, but these resistances are often overcome by the interaction of multiple in field situations. Novel tools allow to decipher plant-microbiome interactions unprecedented detail provide insights into mechanisms that consider both simultaneous attacks various interplay beneficial microbes. Although it has become clear plant-associated microbes play a key role plant health, systematic picture how what extent plants can shape their own detrimental or microbiome remains be drawn. There is increasing evidence for existence genetic variation regulation plant-microbe exploited breeders. We propose entire holobiont breeding strategies order unravel hidden parts complex defence mechanisms. This review summarizes (a) current knowledge soil-borne legumes, (b) rhizosphere-related traits, (c) root exudation microbe-mediated disease elaborates (d) traits incorporated programmes.

Fusarium Wilt Management in Legume Crops

Agronomy, Год журнала: 2020, Номер 10(8), С. 1073 - 1073

Опубликована: Июль 25, 2020

Legumes are among the most important crops worldwide for human and animal consumption. However, yield inconsistency due to susceptibility pests diseases strongly affects its production. Among affecting legumes, Fusarium wilt caused by soil-borne pathogen oxysporum Schltdl. (Fo) is one of major factors limiting production worldwide. This disease can cause total losses in highly infested fields some legume species. To minimize losses, integrated management strategies combining different agronomic practices with use resistant varieties should be applied. Although often characterized a high degree host specificity, formae speciales (ff. spp.) races identified, Fo ff. spp. have broader range, infecting more than species, requiring further investigation. In this review, we describe state art on achievements, highlighting aspects such as rhizosphere microbiota biocontrol agents, crop rotation varieties. The methods identification characterization resistance sources, mechanisms well genetic basis or development molecular tools support precision breeding discussed.

One of the most serious pepper diseases is Phytophthora blight, which caused by capsici. It crucial to assess resistance genetic resources understand resistances, and develop markers for selecting resistant materials in breeding programs. In this study, 342 accessions P. capsici was evaluated. The disease severity score method used evaluate phenotypic responses inoculated with KCP7 isolate. A genome-wide association study (GWAS) performed identify single nucleotide polymorphisms (SNPs) linked (isolate KCP7) resistance. population genotyped using genotype-by-sequencing (GBS) method, 45,481 SNPs were obtained. GWAS analysis evaluation data SNP markers. Significantly associated at 4 weeks after inoculation selected. These blight found on all chromosomes except Chr.05, Chr.09, Chr.11. Chr.02 converted into a high-resolution melting (HRM) marker, another marker (QTL5-1) from previous applied lines validation comparison. This selected because phenotype HRM genotype matched well. named Chr02-1126 located 112 Mb Chr.02. predicted 78.5% accuracy, while QTL5-1 80.2% accuracy. Along major quantitative traits loci (QTLs) could be accurately predict resources. Therefore, will assist selection plants order breed new phytophthora blight-resistant varieties.

Abstract Rhizoctonia solani is a devastating soil-borne pathogen that seriously threatens the cultivation of economically important crops. Multiple strains with very broad host range have been identified, but only 1 (AG1-IA, which causes rice sheath blight disease) has examined in detail. Here, we analyzed AG4-HGI 3 originally isolated from Tartary buckwheat (Fagopyrum tataricum), comparable to AG1-IA. Genome comparison reveals abundant pathogenicity genes this strain. We used multiomic approaches improve efficiency screening for disease resistance genes. Transcriptomes plant–fungi interaction identified differentially expressed associated virulence and buckwheat. Integration jasmonate-mediated transcriptome metabolome changes revealed negative regulator jasmonate signaling, cytochrome P450 (FtCYP94C1), as increasing probably via accumulation resistance-related flavonoids. The integration data 320 accessions gene homolog aspartic proteinase (FtASP), peak expression following R. inoculation. FtASP exhibits no activity functions an antibacterial peptide slows fungal growth. This work potential mechanism behind resistance, should accelerate molecular breeding resistant varieties essential

Multi‐omics analysis reveals the allelic variation in JrWDRC2A9 and JrGPIAP conferring resistance against anthracnose (Colletotrichum gloeosporioides) in walnut (Juglans regia)

The Plant Journal, Год журнала: 2025, Номер 121(3)

Опубликована: Фев. 1, 2025

Walnut anthracnose induced by Colletotrichum gloeosporioides is a devastating disease that seriously threatens walnut cultivation. Screening novel resistance genes and exploring the molecular mechanisms are essential for disease-resistant genetic improvement of walnut. We conducted genome-wide association studies traits based on relative index single nucleotide polymorphisms (SNPs) obtained from 182 resequenced accessions 10 loci corresponding candidate associated with against C. were identified. Then, through combined transcriptome analysis during infection qRT-PCR, we identified JrWDRC2A9 in SNP Chr13_36265784 JrGPIAP Chr07_10106470 as two genes. The validation function transgenic strains indicated both promote to anthracnose. (A>G) located coding region causing glutamine (JrWDRC2A9HapI) arginine (JrWDRC2A9HapII). Allelic variation WD domain attenuates JrWDRC2A9-mediated binding affinity JrTLP1. On contrary, allelic caused (T>G) increased promoting expression level JrGPIAP. Functional genomics revealed binds promoter JrPR1L activates its transcription, which strengthened interaction between JrEMP24. These findings reveal conferring gloeosporioides, providing basis breeding future.
