Plants are able to adjust phenotype in response to changes in the environment. This system depends on an internal capacity to sense environmental conditions and to process this information to plant response. Recent studies have pointed to mitochondria and plastids as important environmental sensors, capable of perceiving stressful conditions and triggering gene expression, epigenomic, metabolic and phytohormone changes in the plant. These processes involve integrated gene networks that ultimately modulate the energy balance between growth and plant defense. This review attempts to link several unusual recent findings into a comprehensive hypothesis for the regulation of plant phenotypic plasticity.
植物能够根据环境变化调整表型。该系统依赖于一种内在的感知环境条件并处理这些信息以响应植物的能力。最近的研究表明，线粒体和质体是重要的环境传感器，能够感知胁迫条件，并触发基因表达、表观基因组、代谢和植物激素变化。这些过程涉及到整合的基因网络，最终调节生长和植物防御之间的能量平衡。本综述试图将最近的一些不寻常发现联系起来，形成一个关于植物表型可塑性调控的综合假说。
