Abstract Harnessing genetic diversity in major staple crops through the development of new breeding capabilities is essential to ensure food security 1 . Here we examined and phenotypic A. E. Watkins landrace collection 2 bread wheat ( Triticum aestivum ), a global cereal, by whole-genome re-sequencing 827 landraces 208 modern cultivars in-depth field evaluation spanning decade. We found that are derived from two seven ancestral groups maintain very long-range haplotype integrity. The remaining five represent untapped sources, providing access landrace-specific alleles haplotypes for breeding. Linkage disequilibrium-based association genetics analyses link genomes thousands identified high-resolution quantitative trait loci significant marker–trait associations. Using these structured germplasm, genotyping informatics resources, revealed many Watkins-unique beneficial can confer superior traits wheat. Furthermore, assessed effects 44,338 haplotypes, introgressed 143 prioritized context cultivars, bridging gap between current This study establishes framework systematically utilizing crop improvement achieve sustainable security.

White clover (Trifolium repens) is a globally important perennial forage legume. This species also serves as an eco-evolutionary model system for studying within-species chemical defense variation; it features well-studied polymorphism cyanogenesis (HCN release following tissue damage), with higher frequencies of cyanogenic plants favored in warmer locations worldwide. Using newly generated haplotype-resolved genome and two other long-read assemblies, we tested the hypothesis that copy number variants (CNVs) at genes play role ability white to rapidly adapt local environments. We examined questions on subgenome evolution this recently evolved allotetraploid chromosomal rearrangements broader IRLC legume clade.

Aconitum is an important medicinal genus widely used in traditional Chinese medicine, which produces types of diterpenoid alkaloids (DA) among different species. We performed whole genome resequencing (WGS) research spp., and wish to find related genetic variations. In this study, we re-sequenced 150 vilmorinianum (A. vilmorinianum) including 102 from the cultivation garden 48 wild, as well nine wild samples weixiense. The intra-population differentiation A. was detected by evolutionary tree population structure inference. identify 47 DA biosynthesis genes that might be highly associated with specialization based on whole-genome resequencing. Of 616 significant SNPs 105 InDels these could developed polymorphic molecular markers capable effectively recognizing Furthermore, were almost homozygous alternates weixiense, whereas they tended references vilmorinianum. Our results discussed difference background compared weixiense high-quality biosynthesis-associated locus provided useful information for discrimination serve a vehicle study mechanism Aconitum.

Abstract Investigating the genetic regulatory mechanisms underlying complex traits forms foundation for crop improvement. Verticillium wilt (VW), caused by dahlia e ( V. dahliae ), is one of most devastating diseases affecting production worldwide. However, basis resistance to remains largely obscure, hindering progress in genomic selection VW breeding. Here, we unraveled architectures and landscape cotton combining genome‐wide association studies (GWAS) transcriptome‐wide (TWAS) using 1152 transcriptomes derived from 290 accessions. We identified 10 reliable quantitative trait loci (QTLs) associated with across multiple environments. These QTLs showed a pyramiding effect exhibited promising efficacy prediction cotton's supported an F 2:3 population. Moreover, trace analysis these elite alleles revealed notably increased utilization Lsnp1, Lsnp4, Lsnp5, Lsnp8, Lsnp9, which potentially contribute improvement Chinese breeding since 1990s. also remarkable gene modules expression QTL (eQTL) hotspots related regulation reactive oxygen species (ROS) homeostasis immune response. Furthermore, 15 candidate causal genes were prioritized TWAS. Knocking down eight negative significantly enhanced . Among them, GhARM , encoding armadillo (ARM)‐repeat protein, was verified modulate regulating ROS homeostasis. Overall, this study updates understanding resistance, providing valuable strategies management through

Cereal grain size and quality are critical agronomic traits in crop production. Wheat development is governed by intricate regulatory networks that require precise spatiotemporal coordination of gene expression to establish functional compartments different cell types. Here, we perform a spatial transcriptomics study covering the early stages wheat development, from 4 12 days after pollination. We classify into 10 distinct types identify 192 marker genes associated with them. WGCNA analysis reveals highly expressed exhibit enrichment patterns, significantly influencing filling. Through co-expression motif analyses, specific group may regulate including TaABI3-B1, transcription factor specifically embryo surrounding endosperm, which negatively affects size. This presents comprehensive transcriptional dataset for understanding development. Additionally, it identifies key genetic resources potential applications improving yield.
