染色质重塑主要包括围绕核小体的组蛋白修饰和染色质重塑蛋白介导的染色质构型调控。染色质重塑介导的基因转录表达调控是植物基因转录调控最重要的调控机制之一。然而，目前对于病原菌侵染诱导的寄主植物核小体动态变化及其与基因转录表达的关系尚不清楚。

万建民 水稻褐飞虱 基因

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，...
