Summary Plant transcription factors (TFs), such as basic helix‐loop‐helix (bHLH) and AT‐rich zinc‐binding proteins (PLATZ), play critical roles in regulating the expression of developmental genes cereals. We identified bHLH protein TaPGS1 ( T. aestivum Positive Regulator Grain Size 1) specifically expressed seeds at 5–20 days post‐anthesis wheat. was ectopically overexpressed (OE) wheat rice, leading to increased grain weight (up 13.81% 18.55% rice lines) size. Carbohydrate total levels also...
Abstract The utilization of stabilized DELLA proteins Rht-B1b and Rht-D1b was crucial for increasing wheat (Triticum aestivum) productivity during the Green Revolution. However, underlying mechanisms remain to be clarified. Here, we cloned a gain-of-function allele GSK3/SHAGGY-like kinase-encoding gene GSK3 by characterizing dwarf mutant. Furthermore, determined that interacts with phosphorylates Revolution protein promote it reduce plant height in wheat. Specifically, phosphorylation may...
Bread wheat (Triticum aestivum) spike architecture is an important agronomic trait. The Q gene plays a key role in the domestication of bread architecture. However, regulatory mechanisms expression and transcriptional activity remain largely unknown.

Indeed, our RACE analyses confirmed mRNA...
Abstract Photoreceptor phytochrome B (phyB) mediates a variety of light responses in plants. To further elucidate the molecular mechanisms phyB‐regulated hypocotyl elongation, we performed firefly luciferase complementation imaging (LCI) screening for phyB‐interacting transcription factors (TFs). LCI assays showed that phyB possibly interacts with brassinazoleresistant 1 (BZR1), BZR2, AUXIN RESPONSE FACTOR 6 (ARF6), and several WRKY DNA‐binding TFs red light‐dependent manner. Furthermore,...
Improvements in plant architecture, such as reduced height under high-density planting, are important for agricultural production. Light and gibberellin (GA) essential external internal cues that affect architecture. In this study, we characterize the direct interaction of distinct receptors link light GA signaling Arabidopsis (Arabidopsis thaliana) wheat (Triticum aestivum L.). We show receptor CRY1 represses through with all five DELLA proteins promotion RGA protein accumulation...
The miR156-targeted SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) transcription factors play key roles in regulating plant development, but little is known about their function abscisic acid (ABA) signaling. Here, we report that the SPLs enhance ABA responses and contribute to inhibition of pre-harvest sprouting. We find SPL9 directly activates expression responsive genes through binding promoters. was further shown physically interact with ABSCISIC ACID INSENSITIVE 5 (ABI5), a master factor...
Plant height is among the most important agronomic traits that influence crop yield. However, in addition to Rht-1 alleles, molecular basis of plant bread wheat remains largely unclear. Based on gene expression profiling analysis, we identify a light-regulated from wheat, designated as TaCOLD1, whose encoding protein homologous cold sensor COLD1 rice. We show TaCOLD1 localized endoplasmic reticulum (ER) and plasma membrane. Phenotypic analyses overexpression mutated form (M187K) cultivar...
Pre-harvest sprouting (PHS) is a significant threat to global food security due its association with losses in both yield and quality. Among the genes involved PHS resistance wheat, PHS-3D (TaMyb10-D) plays crucial role. Here, we characterized sequence variations of TaMyb10 416 bread wheat 302 Aegilops tauschii accessions. Within TaMyb10-A sequences, identified deletion ranging from 214 305 bp signal amino acid coding region, present 61.3% Similarly, 79.3% TaMyb10-B sequences within third...
This study characterizes the responses, particularly diurnal variations, of thyroid hormones (TH) [3,5,3′-triiodothyronine (T3), thyroxine (T4), and T3:T4 ratio (T3/T4)] Arbor Acres broilers to constant thermoneutral (TN) or warm cyclic (WC) temperatures. There existed distinct circadian variations—2 peaks in TH under TN WC conditions. The 2 T3, T4, T3/T4 occurred, respectively, at 0 16 h, 8 12 h condition; but 4 During a 5-d heat exposure (HE) regimens, T3 T4 showed continual decrease....
Plant organ size is an important agronomic trait that greatly determines plant yield. However, despite its central importance, the genetic and molecular mechanisms underlying control remain elusive. Here, we report trithorax group protein ULTRAPETALA1 (ULT1) interacts with TCP14/15 transcription factors (TFs) by antagonizing LIM-peptidase DA1 to regulate in Arabidopsis. Loss of ULT1 function significantly increases rosette leaf, petal, silique seed size, while overexpression results reduced...
<title>Abstract</title> The grain-filling stage is highly sensitive to heat, impacting wheat yield and quality. This study uncovered Chuanmai104's grain spatial transcriptome atlas under heat stress, identifying over 120 specifically expressed genes crucial for cell sorting subsequent sequencing across twelve types. differentiation trajectory of endosperm indicated high expression development programmed death at early stages, the enable grains accumulate nutrients. At 15 DAP, recovery stress...
CONSTANS (CO) is a central regulator of floral initiation in response to photoperiod. In this study, we show that the GSK3 kinase BIN2 physically interacts with CO and gain-of-function mutant bin2-1 displays late flowering phenotype through down-regulation FT transcription. Genetic analyses genetically acts upstream regulating time. Further, illustrate phosphorylates Thr280 residue CO. Importantly, phosphorylation restricts function promoting affecting its DNA-binding activity. Moreover,...
Seed germination relies on preserving mRNA integrity in dry seeds. However, the quality of aged wheat seeds is not well understood. Here, we investigated 20 varieties for seed longevity using controlled deterioration treatment (CDT) and identified that Chinese Spring exhibit moderate longevity. We observed correlations between viability RNA aleurone embryo cells after aging-treatment. Nanopore sequencing whole from natural aging (NAT) CDT 25 days 3,083 full-length transcripts. performed...
Summary Although elevated ambient temperature causes many effects on plant growth and development, the mechanisms of high‐ambient sensing remain unknown. In this study, we show that GLYCOGEN SYNTHASE KINASE 3s (GSK3s) negatively regulate response oligomerize upon high‐temperature treatment. We demonstrate GSK3 kinase BIN2 specifically interacts with sensor phytochrome B (phyB) but not EARLY FLOWER 3 (ELF3) to phosphorylate promote phyB photobody formation. Furthermore, phosphorylation by...

Some also possible effect modification by disease stage, body mass index, receptor status. To date, however, there are no randomized trials examining the effects exercise on outcomes in any patient group. Here, we report an exploratory follow-up from Supervised Trial Aerobic versus Resistance Training (START). Patients...
