A chromosome-scale reference genome and single-nucleus root atlas reveal the cellular and molecular basis of coastal adaptation in sand bean ( Strophostyles helvola )

Quang Tri Le, Xuebo Zhao, Ping Yates, Henry W. Schmidt et autres

Abstract Plants adapted to saline coastal habitats provide valuable systems for understanding how natural selection reshapes stress-response programs, yet the cellular and molecular basis of this adaptation remains poorly resolved. Here, we generated a chromosome-scale reference genome and a single- nucleus transcriptomic …

Graph-based pangenome provides insights into the adaptive evolution of Cucurbita pepo

Xuebo Zhao, Kailiang Bo, Honghe Sun, Jie Zhang et autres

Understanding how crops respond to environmental variation is crucial for biodiversity conservation and food security. Cucurbita pepo (pumpkin, squash, gourd) is one of the first domesticated crop species and exhibits remarkable phenotypic and ecological diversity, making it a powerful system for investigating …

Graph pangenome reveals structural variation dynamics during cucumber breeding

Xuebo Zhao, Jiaojiao Yu, Jie Zhang, Honghe Sun et autres

Structural variants (SVs) represent a significant yet underexplored component of plant genome diversity. Analyzing SV dynamics is essential for understanding their contributions to phenotypic variation and their influence on genome evolution. Here, we present a graph-based pangenome for cucumber, constructed from 39 …

Structural variation discovery in wheat using PacBio high‐fidelity sequencing

Zhiliang Zhang, Jijin Zhang, Lipeng Kang, Xuebing Qiu et autres

Structural variations (SVs) pervade plant genomes and contribute substantially to the phenotypic diversity. However, most SVs were ineffectively assayed due to their complex nature and the limitations of early genomic technologies. By applying the PacBio high-fidelity (HiFi) sequencing for wheat genomes, we …

WPA1 encodes a vWA domain protein that regulates wheat plant architecture

Yongxing Chen, Huixin Xiao, Yuange Wang, Wenling Li et autres

Plant height, spike, leaf, stem and grain morphologies are key components of plant architecture and related to wheat yield. A wheat (Triticum aestivum L.) mutant, wpa1, displaying temperature-dependent pleiotropic developmental anomalies, was isolated. The WPA1 gene, encoding a von Willebrand factor type …

Genomic and pangenomic analyses provide insights into the population history and genomic diversification of bottle gourd

Xuebo Zhao, Jingyin Yu, Bidisha Chanda, Jiantao Zhao et autres

Bottle gourd (Lagenaria siceraria (Mol.) Strandl.) is an economically important vegetable crop and one of the earliest domesticated crops. However, the population history and genomic diversification of bottle gourd have not been extensively studied. We generated a comprehensive bottle gourd genome variation …

The wheat sucrose synthase gene TaSus1 is a determinant of grain number per spike

Liping Shen, Lili Zhang, Changbin Yin, Xiaowan Xu et autres

Some haplotypes of the sucrose synthase gene TaSus1 are associated with thousand-grain weight (TGW) in wheat (Triticum aestivum L.). However, no mutations have been identified within the gene to test this association. The effects of TaSus1 on grain number per spike (GNS) …

Zhiliang Zhang, Jijin Zhang, Lipeng Kang, Xuebing Qiu et autres

Abstract Background Structural variations (SVs) pervade plant genomes and contribute substantially to the phenotypic diversity. However, most SVs were ineffectively assayed because of their complex nature and the limitations of early genomic technologies. The recent advance in third-generation sequencing, particularly the PacBio …

A high-resolution genotype–phenotype map identifies the TaSPL17 controlling grain number and size in wheat

Yangyang Liu, Jun Chen, Changbin Yin, Ziying Wang et autres

BACKGROUND: Large-scale genotype-phenotype association studies of crop germplasm are important for identifying alleles associated with favorable traits. The limited number of single-nucleotide polymorphisms (SNPs) in most wheat genome-wide association studies (GWASs) restricts their power to detect marker-trait associations. Additionally, only a few …
