Abstract Polyploidy occurs prevalently and plays an important role during plant speciation evolution. This phenomenon suggests polyploidy could develop novel features that enable them to adapt wider range of environmental conditions compared with diploid progenitors. Bread wheat (Triticum aestivum L., BBAADD) is a typical allohexaploid species generally exhibits greater salt tolerance than its tetraploid progenitor (BBAA). However, little known about the underlying molecular basis regulatory...
Abstract Cold injury is a major environmental stress affecting the growth and yield of crops. Brassinosteroids (BRs) salicylic acid (SA) play important roles in plant cold tolerance. However, whether or how BR signaling interacts with SA pathway response to still unknown. Here, we identified an methyltransferase, TaSAMT1 that converts methyl (MeSA) confers freezing tolerance wheat (Triticum aestivum). overexpression greatly enhanced tolerance, plants accumulating more MeSA less SA, whereas...
Drought is a major global challenge in agriculture that decreases crop production. γ-Aminobutyric acid (GABA) interfaces with drought stress plants; however, mechanistic understanding of the interaction between GABA accumulation and response remains to be established. Here we showed potassium/proton exchanger TaNHX2 functions as positive regulator resistance wheat by mediating cross-talk stomatal aperture accumulation. interacted glutamate decarboxylase TaGAD1, key enzyme synthesizes from...
Summary Plants have evolved a two‐branched innate immune system to detect and cope with pathogen attack, which are initiated by cell‐surface intracellular receptors leading pattern‐triggered immunity (PTI) effector‐triggered (ETI), respectively. A core transducer including PAD4‐EDS1 node is proposed as the convergence point for two‐tiered in conferring immunity. However, transcriptional regulatory mechanisms controlling expression of these key transducers remain largely unknown. Here, we...
Heat stress (HS) is becoming a major and constant threat to crop production food security as global warming progresses. Consequently, understanding improving tolerance HS are currently among the most important targets in plant biology breeding research (Langridge Reynolds, 2021). Recent evidences suggest epigenetic mechanisms act new layer of regulation cope with (Ohama et al., 2017; Song However, specific regulatory module composed factor transcription establishing thermotolerance remains...
Drought is one of the major environmental stresses limiting crop growth and yield. Epigenetic regulations play crucial roles in plant adaptation to changes, whereas epigenetic mechanism drought resistance crops remains largely elusive. Here, we report that nicotinamide adenine dinucleotide (NAD+)-dependent deacetylase TaSRT1 negatively regulates tolerance wheat. Compared with wild type, tasrt1 mutant had higher relative water contents, along a smaller stomatal aperture improved use...
<title>Abstract</title> Global climate change intensifies drought threats to wheat productivity, necessitating genetic enhancement of resistance. We present a high-quality genome assembly drought-resistant genotype JIN50 (contig N50 = 50.63 Mb) and conduct pan-genomic analyses across 14 genomes 196 germplasms, revealing 430,739 structural variants (SVs). Integrated SV-, SNP-, Indel-based GWAS identified 46 drought-resistance loci enriched in JIN50. Notably, the variation promoter root...
Common wheat (Triticum aestivum, BBAADD) is an allohexaploid species combines the D genome from Ae. tauschii and with AB genomes tetraploid turgidum). Compared wheat, hexaploid has wide-ranging adaptability to environmental adversity such as salt stress. However, little known about molecular basis underlying this trait. The plasma membrane Na+/H+ transporter Salt Overly Sensitive 1 (SOS1) a key determinant of tolerance in plants. Here we show that upregulation TaSOS1 expression positively...
<title>Abstract</title> Drought stress constitutes a major threat for the global wheat production. Identification of genetic components underlying drought tolerance in is great importance. Through genome-wide association study, we identified natural allele zinc finger-type transcription factor TaDT1-A chromosome 2A genome that confers without imposing trade-offs between and yield. This allele, named as TaDT1-AhapⅠ, causes an 899-bp deletion promoter gene, which results enhanced expression...
