棉花是一种重要的工业作物,逐渐转向在干旱地区种植。然而,参与植物响应各种胁迫的Tubby-like protein,TULP在棉花中很少被报道。本研究通过调节气孔运动,展示了GhTULP30对植物耐受干旱胁迫的改进。GhTULP30在酵母中的异源表达显著提高了其抗盐和干旱耐受性。GhTULP30的过表达使得拟南芥种子在种子萌发期间更加抵御干旱和盐胁迫,并且在干旱胁迫条件下提高了该植物的气孔关闭速度...
Rice originated in tropical and subtropical regions and is distributed worldwide. Low temperature is one of the most critical abiotic stresses affecting grain yield and geographical distribution of ri...
Nitroaromatic compounds, as the important chemical feedstock, have caused widespread environmental contaminations, and exhibited high toxicity and mutagenic activity to nearly all living organisms. Th...
GhN/AINV13通过与14-3-3蛋白互作正调控棉花抗逆能力中性/碱性转化酶(N/AINVS)是植物中具有重要作用的蔗糖水解酶。在本研究中,分别在雷蒙德氏棉、非洲棉、亚洲棉、陆地棉、海岛棉中鉴定到15、15、15、29以及30个中性/碱性转化酶基因。除了前人发现的α和β亚族之外,我们的研究中首次发现了一个新亚族。基因的共线性研究表明,全基因组复制(WGD)和多倍体化是异源多倍体棉N/AINV基...
土壤盐渍化是影响植物生长和农作物产量等非常严峻的环境问题,盐渍化荒地的开发和改良成为亟待解决的全球性问题。虽然棉花是一种比较耐盐的农作物,但土壤盐分浓度过大也会对棉花产生严重的危害,尤其是种子萌发期对盐胁迫十分敏感。缩节胺(MC)是棉花生产上用来调控棉株长势长相促进丰产比较成功的植物生长延缓剂;除了控制棉花徒长,MC浸种对棉花的生理特性也会产生显著影响,可促进棉花根系发育、提高根系活力,因此MC浸...
Salt stress is an important factor that limits rice yield. We identified a novel, strongly salt tolerant rice landrace called Changmaogu (CMG) collected from a coastal beach of Zhanjiang, Guangdong Pr...
Plants maintain a dynamic balance between plant growth and stress tolerance to optimize their fitness and ensure survival. Here, we investigated the roles of a clade A type 2C protein phosphatase (PP2...
To understand the functions of transcription factor OsNAC5 in response to abiotic stress, we generated transgenic rice plants with knockdown OsNAC5 by RNAinterfered (RNAi) and overexpressing OsNAC5, a...
Thirty eight novel microsatellite markers (SSRs) specific to candidate genes involved in salt tolerance were developed for detection of genetic variations in 12 mungbean genotypes variably adapted to ...
As an important antioxidant for plants and humans, L-ascorbic acid (AsA, vitamin C) can scavenge reactive oxygen species (ROS) and can be regenerated from its oxidized form in a reaction catalyzed by ...
Wheat is one of the most important crops in the world. Its yield is greatly influenced by global climate change and scarcity of water in the arid and semi-arid areas of the world. So, exploration of g...
Rains during grain ripening in wheat (Triticum aestivum L.) can cause preharvest sprouting (PHS), which drastically affects the grain yield and the baking quality of flour. In the present study, to sc...
The effect of drought stress on yield and its components was studied on 28 new hybrids of maize along with 6 commercial control hybrids at the Khorasan Razavi Agricultural Research and Natural Resourc...
The sequences of the closely linked barley dehydrin genes Dhn4 and Dhn7 are both known to vary allelically. Here we associated allelic constitution at Dhn4/7 with frost sensitivity across a panel of 3...
Salinity tolerance has been extensively studied in Oryza sativa, but little is known about the salt tolerance levels in Oryza glaberrima and the interspecific progenies including New Rice for Africa (...
