报告题目：解码细胞器-RNA结合蛋白的奋斗日常

报告摘要：

线粒体和叶绿体作为植物细胞中两类关键的细胞器，其大部分基因已经迁移到细胞核基因组或在进化过程中丢失。高等植物细胞器 RNA 的代谢调控十分复杂，主要涉及转录后加工过程。细胞器基因表达、生物发生及功能实现所需的大多数蛋白因子由细胞核基因所编码。这些核基因编码蛋白如何调控细胞器基因表达，并进而影响植物生长发育及繁殖，一直是植物学基础理论和作物杂交育种的核心研究课题之一。

TITLE： 

Cracking the Organelle Code: RNA-Binding Proteins at Work 

ABSTRACT：

Mitochondria and chloroplasts, as two key organelles in plant cells, have most of their genes either transferred to the nuclear genome or lost during evolution. The metabolic regulation of RNA in higher plant organelles is highly complex, primarily involving post-transcriptional processing. Most protein factors necessary for the expression, biogenesis, and functional realization of organelle genes are encoded by nuclear genes. How these nuclear-encoded proteins regulate organelle gene expression, and consequently affect plant growth, development, and reproduction, has always been a core research topic in fundamental plant biology and crop hybrid breeding.
