Light is a predominant factor in the control of plant growth, development and stress responses. Many biotic stress responses in plants are therefore specifically adjusted by the prevailing light conditions. The plant cell is equipped with sophisticated light-sensing mechanisms that are localised inside and outside of the chloroplast and the nucleus. Recent progress has provided models of how the signalling pathways that are involved in light perception and in defence could operate and interact to form a plant defence network. Such a signalling network includes systems to sense light and regulate gene expression. Photo-produced H(2)O(2) and other reactive oxygen species in the cell also play an essential role in this regulatory network, controlling biotic and abiotic stress responses.
光是控制植物生长、发育和应激反应的主要因素。因此，植物中的许多生物应激反应会根据当前的光照条件进行特异性调节。植物细胞配备了复杂的光感知机制，这些机制位于叶绿体和细胞核的内部及外部。最近的研究进展提供了一些模型，说明参与光感知和防御的信号通路是如何运作和相互作用，从而形成一个植物防御网络的。这样一个信号网络包括感知光和调节基因表达的系统。细胞中光产生的过氧化氢和其他活性氧在这个调节网络中也起着至关重要的作用，控制着生物和非生物应激反应。
