万建民 水稻褐飞虱 基因
2023/10/28
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，...
Ethylene negatively regulates aluminium-induced malate efflx from wheat roots and tobacco cells transformed with TaALMT1
Ethylene aluminium tolerance malate efflx ALMT1 wheat (Triticum aestivum L.)
2015/2/5
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...
Elevated CO2 decreases the response of the ethylene signaling pathway in Medicago truncatula and increases the abundance of the pea aphid
Acyrthosiphon pisum (pea aphid) elevated CO2 ethylene Medicago truncatula nitrogen (N) metabolism resistance
2015/2/5
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-responsive miRNAs in roots of Medicago truncatula identified by high-throughput sequencing at whole genome level

Salt stress Brassinosteroids Ethylene Seed germination Cucumis sativus
2015/2/5
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...
Stimulation of root acid phosphatase by phosphorus deficiency is regulated by ethylene in Medicago falcata
Phosphorus deficiency Ethylene Medicago falcata Acid phosphatase activity Phosphate transporters Organic phosphorus
2015/2/5
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...

Aluminium-induced inhibition of root elongation in Arabidopsis is mediated by ethylene and auxin
Aluminium toxicity Arabidopsis thaliana auxin polar transport ethylene root elongation
2015/2/5
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...
Ethylene is involved in nitrate-dependent root growth and branching in Arabidopsis thaliana
