Hybrid necrosis, a century-old mystery in wheat, is caused by complementary genes Ne1 and Ne2. Ne2, encoding nucleotide-binding leucine-rich repeat (NLR) immune receptor, has been cloned, yet remains elusive. Here, we report that Ne1, which encodes an alpha/beta hydrolase (ABH) protein generated structural variation, triggers hybrid necrosis with Ne2 activating autoimmune responses. We further verify not only allelic variation but also copy number (CNV) of are pivotal for diversity wheat. likely originates from wild emmer potentially through duplication ectopic recombination events. Unlike frequently selected rust resistance wheat breeding, the lower prevalence modern cultivars attributed to its association necrosis. Altogether, these findings illuminate co-evolution NLR/ABH gene pair plant development innate immunity, offering potential benefits breeding. The underlying mechanism enigmatic.

Zinc (Zn) is a chemical element essential to plant growth and development, soil Zn deficiency restricts agricultural production. Understanding the regulatory mechanism of uptake in bread wheat (Triticum aestivum) critical for improving production Zn-deficient regions. In this study, zinc-regulated transporters, iron-regulated transporter-like protein 10 (TaZIP10) was identified as functional transporter. The TaZIP10 exhibits Zn-transport activity yeast localizes plasma membrane. gene mainly expressed roots, its expression induced by deficiency. Silencing resulted decreased acquisition seedlings. Furthermore, we demonstrated that promoter-associated WRKY-type transcription factor 1 (TaZPAW1) directly binds promoter regions functions transcriptional repressor. Importantly, found TaZPAW1 interacts with histone deacetylase TaZIHD1 (TaZPAW1-interacting 1) recruits mediate deacetylation, which leads epigenetic suppression expression. addition, showed silencing or potentiated acquisition. These findings support concert negatively regulate presumably via epigenetically suppressing transporter gene.

Abstract LMW-GS are one of the primary components wheat (Triticum aestivum L.) seed storage proteins, which have an important impact on end-use quality traits. Identifying genes accurately within genomes has consistently presented a significant challenge. LMWgsFinder developed by this study was used to re-identify in total 26 grass family. Apart from six species, 291 were identified. Except for two versions TaCS Chinese Spring) genome, only 38.13% (98/257) identified annotated coding sequence (CDS) annotation files (provided sequencing research groups) remaining 18 genomes.

Abstract Breeding crops resilient to climate change is urgently needed help ensure food security. A key challenge harness genetic diversity optimise adaptation, yield, stress resilience and nutrition. We examined the phenotypic of A.E. Watkins landrace collection bread wheat ( Triticum aestivum ), a major global cereal, through whole-genome re-sequencing (827 landraces 208 modern cultivars) in-depth field evaluation spanning decade. discovered that cultivars are derived from just two seven ancestral groups wheat, leaving five as previously untapped sources for breeding. This provides access landrace-specific functional variations using structured germplasm, genotyping informatics resources. Employing complementary populations approaches, we identified thousands high-resolution quantitative trait loci (QTL) significant marker–trait associations traits, revealing many Watkins-unique can confer superior traits in wheat. Furthermore, functionally verified causative genes climate-change nutritional enhancement resistance blast.
