ABSTRACT Chemically‐interfered male sterility (CIMS) system in wheat ( Triticum aestivum L.) is one of the types used for hybrid production China. The main morphological defect sterile line 1376‐CIMS interfered by chemical hybridizing agents (CHA) that tapetum seems to be abnormally degrated and pollen extine aberrant. As a complex wall wheat, outer mainly contains lipidic sporopollenin. However, mechanism synthesizing these aliphatic precursors during development has not been fully...
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...
Male reproductive development in higher plants is highly sensitive to various stressors, including high temperature (HT). In this study, physiological male-sterile of wheat (Triticum aestivum L.) were established using HT induction. The changes and expression levels genes mainly related carbohydrate metabolism sporopollenin processes studied by biological techniques, iodine–potassium iodide staining, paraffin sectioning, scanning electron microscopy (SEM) fluorescent quantitative analysis....
Malondialdehyde (MDA), which is thought to be important inducible factor of cell apoptosis if excessively accumulated in cells, often regarded as a widely used marker oxidative lipid injury whose concentration varies response biotic and abiotic stress.To elucidate the metabolic mechanism ROS production scavenging male sterility, normal fertility sterility wheat, including genetic physiologically by comparing MDA content antioxidant enzymes changes sterile fertile leaves, spikes, florets,...
K-Type cytoplasmic male sterility (K-CMS) plays an important role in breeding hybrid wheat. This study was designed to investigate the association of sucrose metabolism with K-CMS wheat (Triticum aestivum L.) anthers at binucleate stage. Levels line remained higher than fertile line, but glucose and fructose contents were dramatically lower line. Compared activities cell-wall-bound invertase (CWIN), neutral vacuolar (VIN) significantly reduced. Quantitative real-time polymerase chain...
DNA methylation is an important epigenetic modification that may contribute to environmentally induced phenotypic variations by regulating gene expression. Chemically male sterility (CIMS) lines in wheat (Triticum aestivum L.) can transform from sterile fertile, a chemical hybridising agent during anther development. So far, little known about the variation of CIMS wheat. TAA1 regulates pollen wall development, probably through converting fatty acids alcohol We investigated pattern core...
Chemically induced male sterility (CIMS) is one of the system used for hybrid wheat production in China. However, mechanism remains unclear. The expression chalcone synthase (CHS) gene was assessed anthers to determine its role fertility/sterility wheat. levels CHS evaluated by realtime quantitative polymerase chain reaction (qPCR). qPCR analysis revealed that were downregulated CIMS. sporopollenin contents underwent a sharp decrease 1376-CIMS. Scanning electron microscopy observations...
In wheat (Triticum aestivum L.), S-type cytoplasmic male sterile (S-CMS) lines can mainly transform from sterility to fertility at the mononuclear pollen stage. Observations microscopy revealed an inhibition of starch accumulation within grain, suggesting that alteration in carbohydrate metabolism or assimilate supply may be involved S-CMS abortion. We measured levels various carbohydrates and activities key enzymes sucrose stage anthers collected line its maintainer found nonreducing sugars...
