Abstract Background Tartary buckwheat, Fagopyrum tataricum , is a pseudocereal crop with worldwide distribution and high nutritional value. However, the origin domestication history of this remain to be elucidated. Results Here, by analyzing population genomics 567 accessions collected reviewing historical documents, we find that buckwheat originated in Himalayan region then spread southwest possibly along migration Yi people, minority Southwestern China has long planting buckwheat. Along expansion Mongol Empire, dispersed Europe ultimately rest world. The different natural growth environments resulted adaptation, especially significant differences salt tolerance between northern southern Chinese populations. By scanning for selective sweeps using genome-wide association study, identify genes responsible differentiation, which experimentally validate. Comparative QTL analysis further shed light on genetic foundation easily dehulled trait particular variety was artificially selected Wa group known cultivating specifically steaming as staple food prevent lysine deficiency. Conclusions This study provides both comprehensive insights into of, molecular breeding for,

Multi‐omics identification of a key glycosyl hydrolase gene FtGH1 involved in rutin hydrolysis in Tartary buckwheat (Fagopyrum tataricum)

Plant Biotechnology Journal, Год журнала: 2023, Номер 22(5), С. 1206 - 1223

Rutin, a flavonoid rich in buckwheat, is important for human health and plant resistance to external stresses. The hydrolysis of rutin quercetin underlies the bitter taste Tartary buckwheat. In order identify genes, 200 genotypes mini-core buckwheat germplasm resource was re-sequenced with 30-fold coverage depth. By combining content intermediate metabolites metabolism genome resequencing data, metabolite genome-wide association analyses (GWAS) eventually identified glycosyl hydrolase gene FtGH1, which could hydrolyse quercetin. This function validated both overexpression hairy roots vitro enzyme activity assays. Mutation two key active sites, were determined by molecular docking experimentally verified via transient expression tobacco leaves, exhibited abnormal subcellular localization, suggesting functional changes. Sequence analysis revealed that mutation FtGH1 promoter accessions haplotypes might be necessary enzymatic activity. Co-expression GWAS FtbHLH165 not only repressed expression, but also increased seed length. work reveals potential mechanism behind metabolism, should provide theoretical support study breeding

Buckwheat UDP‐Glycosyltransferase FtUGT71K6 and FtUGT71K7 Tandem Repeats Contribute to Drought Tolerance by Regulating Epicatechin Synthesis

Plant Cell & Environment, Год журнала: 2025, Номер unknown

Glycosyltransferase genes are organised as tandem repeats in the buckwheat genome, yet functional implications and evolutionary significance of duplicated remain largely unexplored. In this study, gene family analysis revealed that FtUGT71K6 FtUGT71K7 genome. Moreover, GWAS results for epicatechin suggested repeat function was associated with content Tartary germplasm, highlighting variations promoter haplotypes influenced levels. were shown to catalyse UDP-glucose conjugation cyanidin epicatechin. Furthermore, overexpression increased total antioxidant capacity altered metabolite biosynthesis pathway, contributing improved drought tolerance, while significantly salt stress tolerance. However, these two did not contribute resistance against Rhizoctonia solani. Evolutionary selection pressure positive a critical amino acid ASP-53 during duplication event. Overall, our study indicated play crucial roles tolerance via modulating synthesis buckwheat.

Distinct Infection Mechanisms of Rhizoctonia solani AG-1 IA and AG-4 HG-I+II in Brachypodium distachyon and Barley

Life, Год журнала: 2025, Номер 15(2), С. 235 - 235

Опубликована: Фев. 5, 2025

Rhizoctonia solani is a basidiomycete phytopathogenic fungus that causes rapid necrosis in wide range of crop species, leading to substantial agricultural losses worldwide. The species complex divided into 13 anastomosis groups (AGs) based on hyphal fusion compatibility and further subdivided by culture morphology. While R. classifications were shown be independent host specificity, it remains unclear whether different isolates share similar virulence mechanisms. Here, we investigated the infectivity Japanese Brachypodium distachyon barley. Two isolates, AG-1 IA (from rice) AG-4 HG-I+II cauliflower), infected leaves both plants, but only roots. B. accessions Bd3-1 Gaz-4 barley cultivar ‘Morex’ exhibited enhanced resistance compared Bd21 cultivars ‘Haruna Nijo’ ‘Golden Promise’. During infection, not resistant Morex induced genes for salicylic acid (SA) N-hydroxypipecolic (NHP) biosynthesis. Pretreatment with SA or NHP conferred IA, HG-I+II, susceptible Haruna Nijo. On Nijo, developed extensive mycelial networks numerous infection cushions, which are specialized structures well-characterized rice sheath blight. In contrast, formed dispersed masses associated underlying necrosis. We propose encompasses at least two distinct strategies: exhibits hemibiotrophic lifestyle, while follows predominantly necrotrophic strategy.

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)

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.
