VQ motif-containing proteins play important roles in plant abiotic and biotic stresses. In this study, we cloned the protein gene TaVQ4-D that is induced by drought stress. Arabidopsis wheat plants overexpressing showed increased tolerance to contrast, lines which expression had been silenced decreased tolerance. Under stress conditions, contents of superoxide dismutase proline content malondialdehyde transgenic compared with wild type. At same time, reactive oxygen...
The WUSCHEL-related homeobox (WOX) is a family of plant-specific transcription factors, with important functions, such as regulating the dynamic balance division and differentiation plant stem cells organ development. We identified 14 distinct TaWOX genes in wheat (Triticum aestivum L.) genome, based on genome-wide scan approach. All under evaluation had positional homoeologs subgenomes A, B D except TaWUS TaWOX14. Both TaWOX14a TaWOX14d paralogous copy same genome due to tandem duplication...
CLAVATA3/EMBRYO SURROUNDING REGION (CLE) peptides are post-translationally cleaved and modified from their corresponding pre-propeptides. Although they only 12 to 13 amino acids in length, important ligands involved regulating cell proliferation differentiation plant shoots, roots, vasculature, other tissues. They function by interacting with receptors. CLE have been studied many plants, but not wheat. We identified 104 TaCLE genes the wheat genome based on a genome-wide scan approach. Most...
Wheat (Triticum aestivum L.), one of the world's most important food crops, is a strictly autogamous (self-pollinating) species with exclusively perfect flowers. Male sterility induced by chemical hybridizing agents has increasingly attracted attention as tool for hybrid seed production in wheat; however, molecular mechanisms male agent SQ-1 remain poorly understood due to limited whole transcriptome data. Therefore, comparative analysis wheat anther transcriptomes fertile and SQ-1–induced...
Heterosis is widely used to increase the yield of many crops. However, as wheat a self-pollinating crop, hybrid breeding not so successful in this organism. Even though male sterility induced by chemical hybridizing agents an important aspect crossbreeding, mechanisms which these induce well understood. We performed proteomic analyses using Triticum aestivum L.to identify those proteins involved physiological (PHYMS) agent CHA SQ-1. A total 103 differentially expressed were found 2D–PAGE and...
This study used semi-thin sectioning and cytochemistry to investigate the relationship between pollen nutrient metabolism abortion in male sterile lines of wheat induced by SQ-1 (a chemical hybridising agent). Anthers were collected from tetrad trinucleate stages, 4ʹ,6-diamidino-2-phenylindole staining was visualise nuclei confirm development stage. Sudan Black B, periodic acid–Schiff, Coomassie Brilliant Blue, toluidine blue detect lipids, starch, proteins, acidic polyanions, respectively....
Pollen fertility plays an important role in the application of heterosis wheat (Triticum aestivum L.). However, key genes and mechanisms underlying pollen abortion K-type male sterility remain unclear. TAA1a is essential gene for development wheat. Here, we explored mechanism involved its transcriptional regulation during development, focusing on a 1315-bp promoter region. Several cis-acting elements were identified promoter, including binding motifs Arabidopsis thaliana AtAMS AtMYB103...
ABSTRACT Induction of male sterility by chemical‐hybridizing agents is important in heterosis breeding, especially for self‐pollinated crops like wheat ( Triticum aestivum L.). This study was designed to investigate the association carbohydrate metabolism with chemical‐induced (CIMS) anthers. Transverse section observation showed that during young microspore (YM) stage, tapetum fertile line anthers began degenerate, while CIMS delayed degradation. The levels nonreducing sugars always...
K-type cytoplasmic male sterility (KCMS) lines were ideal material for three-line hybrid wheat system due to the major role in production. In this study, morphology of developing microspore and mature pollen was compared between a KCMS line its near-isogenic restorer (KCMS-NIL). The most striking difference is that unable develop into tricellular line. MicroRNA plays vital roles flowering gametophyte development. Small RNA sequencing identified total 274 known 401 novel miRNAs differentially...
DUOII is a multi-ovary wheat (Triticum aestivum L.) line with two or three pistils and stamens in each floret. The trait of controlled by dominant gene, whose expression can be suppressed the heterogeneous cytoplasm TeZhiI (TZI), nucleus common Aegilops. Crosses between female plants male TZI resulted F1s; whereas, reciprocal crosses mono-ovary F1s. Although inherited as single allele lines Triticum cytoplasm, mechanism which special suppresses not well understood. Observing developmental...
ABSTRACT This study investigated the relationship between abnormal degeneration of tapetum and pollen abortion in an SQ‐1‐induced male‐sterile line wheat ( Triticum aestivum L.), using semithin sectioning cytochemistry. Anthers were collected from tetrad through trinucleate stages, 1.5% (w/v) acetocarmine staining was used to confirm developmental stage. Lipids, polysaccharides, proteins detected by staining, area, mean optical density, integrated density calculated. Microspores had a...
Variety DUOII is a multi-ovary line of common wheat (Triticum aestivum L.) that has two or three pistils and stamens. The trait controlled by dominant gene, the expression which can be suppressed special heterogeneous cytoplasm TeZhiI (TZI). TZI nucleus Aegilops. (♀) × (♂) shows trait, whereas mono-ovary trait. DNA methylation affects gene plays crucial role in organ tissue differentiation. In order to study relationship between suppression we used methylation-sensitive amplification...
In plants, pollen grain transfers the haploid male genetic material from anther to stigma, both between flowers (cross-pollination) and within same flower (self-pollination). order better understand chemical hybridizing agent (CHA) SQ-1-induced abortion in wheat, comparative cytological proteomic analyses were conducted. Results indicated that grains underwent serious structural injury, including cell division abnormality, nutritional deficiencies, wall defect malformations CHA-SQ-1-treated...
Chlorophyll is an indispensable photoreceptor in plant photosynthesis. Its anabolic imbalance detrimental to individual growth and development. As essential epigenetic modification, DNA methylation can induce phenotypic variations, such as leaf color transformation, by regulating gene expression. Albino line XN1376B a natural mutation of winter wheat cultivar XN1376; however, the regulatory mechanism its albinism still unclear. In this study, we found that low temperatures induced XN1376B....
DNA methylation plays an important role in regulating plant development, including organ and tissue differentiation, which may determine variations agronomic traits. However, no reports exist for the regulation of leaf colour wheat. The present study investigated chloroplast structure epigenetic mechanisms albino mutant wheat (Triticum aestivum L.) cv. Xinong 1376. Structural analysis was performed by scanning transmission electron microscopy, modifications were detected...
Heterosis has been widely accepted as an effective strategy to increase yields in plant breeding. Notably, the chemical hybridization agent SQ-1 induces male sterility wheat, representing a critical potential tool hybrid seed production. However, mechanisms underlying induced by still remain poorly understood. In this study, cyclin-dependent kinase inhibitor gene, TaICK1, which encodes 229 amino acid protein, was identified contributor common wheat. The expression of TaICK1 upregulated...

Chlorophyll biosynthesis plays a vital role in chloroplast development and photosynthesis plants. In this study, we identified an orthologue of the rice gene TDR (Oryza sativa L., Tapetum Degeneration Retardation) wheat (Triticum aestivum L.) called TaTDR-Like (TaTDRL) by sequence comparison. TaTDRL encodes putative 557 amino acid protein with basic helix-loop-helix (bHLH) conserved domain at C-terminal (295–344 aa). The localised to nucleus displayed transcriptional activation activity...
Microtubules play a fundamental role in plant development, morphogenesis, and cytokinesis; they are assembled from heterodimers containing an α-tubulin (TUA) β-tubulin (TUB) protein. However, little research has been conducted on the TUA TUB gene families hexaploid wheat (Triticum aestivum L.). In this study, we identified 15 TaTUA 28 TaTUB genes wheat. Phylogenetic analysis showed that were divided into two major subfamilies, five subfamilies. Mostly, there similar motif compositions...
