英文摘要 | Chloroplast retrograde signals play important roles in coordinating the plastid and nuclear gene expression and are critical for proper chloroplast biogenesis and for maintaining optimal chloroplast functions in response to environmental changes in plants. until now, the signals and the mechanisms for retrograde signalling remain poorly understood. here we identify factors that allow the nucleus to perceive stress conditions in the chloroplast and to respond accordingly by inducing or repressing specific nuclear genes encoding plastid proteins. we show that abi4, which is known to repress the lhcb genes during retrograde signalling, is activated through phosphorylation by the map kinases mpk3/mpk6 and the activity of these kinases is regulated through 14-3-3 omega-mediated ca2+-dependent scaffolding depending on the chloroplast calcium sensor protein cas. these findings uncover an additional mechanism in which chloroplast-modulated ca2+ signalling controls the mapk pathway for the activation of critical components of the retrograde signalling chain. |
