Abstract

Chloroplasts are one of the defining features in most plants, primarily known for their unique property to carry out photosynthesis. Besides this, chloroplasts are also associated with hormone and metabolite productions. For this, biogenesis and development of chloroplast are required to be synchronized with the seedling growth to corroborate the maximum rate of photosynthesis following the emergence of seedlings. Chloroplast biogenesis and development are dependent on the signaling to and from the chloroplast, which are in turn regulated by several endogenous and exogenous cues. Light and hormones play a crucial role in chloroplast maturation and development. Chloroplast signaling involves a coordinated two-way connection between the chloroplast and nucleus, termed retrograde and anterograde signaling, respectively. Anterograde and retrograde signaling are involved in regulation at the transcriptional level and downstream modifications and are modulated by several metabolic and external cues. The communication between chloroplast and nucleus is essential for plants to develop strategies to cope with various stresses including high light or high heat. In this review, we have summarized several aspects of chloroplast development and its regulation through the interplay of various external and internal factors. We have also discussed the involvement of chloroplasts as sensors of various external environment stress factors including high light and temperature, and communicate via a series of retrograde signals to the nucleus, thus playing an essential role in plants’ abiotic stress response.

内源和外源线索对叶绿体生物发生、发育和信号传导的调控
摘要 叶绿体是大多数植物的显著特征之一,主要以其进行光合作用的独特特性而闻名。除此之外,叶绿体还与激素和代谢产物的产生有关。因此,叶绿体的生物发生和发育需要与幼苗的生长同步,以确保幼苗萌发后光合作用的最大速率。叶绿体的生物发生和发育依赖于叶绿体之间的信号传递,而叶绿体之间的信号传递又受多种内源和外源信号的调节。光和激素在叶绿体的成熟和发育过程中起着至关重要的作用。叶绿体信号传递涉及叶绿体和细胞核之间协调的双向联系,分别称为逆行信号传递和顺行信号传递。前向信号和逆向信号参与转录水平的调节和下游修饰,并受多种代谢和外部线索的调节。叶绿体和细胞核之间的交流对于植物制定应对各种胁迫(包括强光或高温)的策略至关重要。在本综述中,我们总结了叶绿体发育的几个方面以及通过各种内外因素的相互作用对其进行调控的情况。我们还讨论了叶绿体作为各种外部环境胁迫因子(包括强光和高温)的传感器,通过一系列逆行信号与细胞核进行交流,从而在植物的非生物胁迫响应中发挥重要作用。
