摘要
叶绿体不仅是植物进行光合作用的关键场所,而且还参与质体逆行信号传递,以响应发育和环境信号。MEcPP(2-C-甲基-D-赤藓糖醇-2,4-环焦磷酸)是叶绿体中赤藓糖醇磷酸甲酯(MEP)途径的中间体。它是合成异戊烯类和萜类衍生物的重要前体,在植物生长发育、光合作用、繁殖和抵御环境限制等方面起着至关重要的作用。在胁迫条件下,MEcPP 的积累会触发 IMPα-9 和 TPR2 的表达,从而激活非生物胁迫响应基因。在这篇通讯中,我们讨论了质体逆行信号转导,以支持最近发表在《分子植物》(Molecular Plant)上的一篇论文(Zeng et al.我们希望这篇论文能让我们对逆行信号级联有更深入的了解。
Chloroplasts are not only critical photosynthesis sites in plants, but they also participate in plastidial retrograde signaling in response to developmental and environmental signals. MEcPP (2-C-Methyl-D-erythritol-2,4-cyclopyrophosphate) is an intermediary in the methylerythritol phosphate (MEP) pathway in chloroplasts. It is a critical precursor for the synthesis of isoprenoids and terpenoid derivatives, which play crucial roles in plant growth and development, photosynthesis, reproduction, and defense against environmental constraints. Accumulation of MEcPP under stressful conditions triggers the expression of IMPα-9 and TPR2, contributing to the activation of abiotic stress-responsive genes. In this correspondence, we discuss plastidial retrograde signaling in support of a recently published paper in Molecular Plant (Zeng et al. 2024). We hope that it can shed more insight on the retrograde signaling cascade.
期刊介绍:
Functional & Integrative Genomics is devoted to large-scale studies of genomes and their functions, including systems analyses of biological processes. The journal will provide the research community an integrated platform where researchers can share, review and discuss their findings on important biological questions that will ultimately enable us to answer the fundamental question: How do genomes work?
