褐飞虱是水稻生产中最严重的害虫。褐飞虱通过针状口器刺入水稻叶鞘组织吸食韧皮部汁液,造成水稻严重减产甚至绝收。种植抗性品种是综合防控褐飞虱的基础。然而植物抗病虫性通常受光照、温度和湿度等环境因素的影响,在一定程度上制约了抗性基因的有效利用。如采用密植的栽培方式是当前许多作物增加单位面积产量的重要途径,但是密植通常会导致冠层以下的植株部分光照不足而产生庇荫反应,易滋生各类病虫害,虽然这种现象普遍存在,...
An important mechanism for Al3+ tolerance in wheat is exudation of malate anions from the root apex through activation of malate-permeable TaALMT1 channels. Here, the effect of ethylene on Al3+-activa...
The performance of herbivorous insects is greatly affected by plant nutritional quality and resistance, which are likely to be altered by rising concentrations of atmospheric CO2.We previously repor...
Ethylene is one ofthe classical plant hormones with a diverse function in plant growth and development. Root elongation is sensitive to ethylene such that treatments with ethylene and the ethylene pre...
Brassinosteroids are a class of plant polyhydroxysteroids with a diverse of functions in plant growth and development, while ethylene is a gaseous hormone involved in regulation of numerous physiologi...
Plants have developed numerous strategies to cope with phosphorus (P) deficiency resulting from low availability in soils. Evolution of ethylene and up-regulation of root secreted acid phosphatase act...
Ethylene is an important plant gas hormone, and the amino acid Glu is emerging as a messenger molecule inplants.ToevaluatetheroleofethyleneandGluinseedgerminationandradiclegrowthundersaltstress, effec...
Aluminium (Al) is phytotoxic when solubilized into Al3+ in acidic soils. One of the earliest and distinct symptoms of Al3+ toxicity is inhibition of root elongation. To decipher the mechanism by which...
Here, we investigated the role of ethylene in high nitrate-induced change in root development in Arabidopsis thaliana using wild types and mutants defective in ethylene signaling (etr1, ein2) and nitr...
Plants grown in phosphorus-deficient solutions often exhibit disruption of water transport due to reduction in root hydraulic conductivity (Lpr) and enhanced ethylene production. To uncover the relati...
Inhibition of root elongation by toxic aluminum (Al3+) occurs rapidly and is one of the most distinct and earliest symptoms of Al toxicity. To elucidate mechanism underlying Al3+-induced inhibition of...
Here, the effects of the ethylene-releasing compound, ethephon, and the ethylene precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), on ionic currents across plasma membranes and on the cytosolic ...
Using a combined theoretical and experimental approach, we investigate the non-adiabatic dynamics of the prototypical ethylene (C2H4) molecule upon π → π* excitation. In this first part of a two part ...
Tri(ethylene glycol) terminated short alkylchain thiols (TEGCnSHs) offer good potential for constructing ultra-thin protein-resistant monolayers because they have an alkylchain for forming a densely p...
通过拉曼光谱方法分别对PEDOT:PSS掺杂和去掺杂状态进行了详细分析。实验结果表明,去掺杂的PEDOT:PSS由于其在激发波长附近的吸收增强而引起了共振效应,拉曼信号得到大幅度增强,可见,以633 nm(He-Ne)激光为激发波长的拉曼光谱是研究PEDOT:PSS掺杂状态的有效方法。此外,显微拉曼光谱也是分析聚合物发光二极管器件内各层材料的有效手段。
