叶绿体RNA剪接和核糖体成熟（CRM）结构域蛋白调控叶绿体或线粒体基因的表达，影响植物的生长和发育。虽然14 CRM结构域蛋白先前已被确定在水稻中，有这些基因在各种组织和非生物胁迫下的表达模式的研究很少。在我们的研究中，我们发现14个CRM结构域含有蛋白质具有保守的基序1。在盐胁迫下，14个CRM基因的表达水平下调。而在干旱和低温胁迫下，一些CRM基因的表达量增加。基因表达谱分析表明，14个CRM基因在所有组织中均有表达，但在叶片中表达量最高。此外，我们分析了OsCFM 2的功能，发现该蛋白通过调节I组和5组II内含子的剪接来影响叶绿体发育。本研究为水稻CRM结构域蛋白的功能分析提供了依据。
The chloroplast RNA splicing and ribosome maturation (CRM) domain-containing proteins regulate the expression of chloroplast or mitochondrial genes that influence plant growth and development. Although 14 CRM domain proteins have previously been identified in rice, there are few studies of these gene expression patterns in various tissues and under abiotic stress. In our study, we found that 14 CRM domain-containing proteins have a conservative motif1. Under salt stress, the expression levels of 14 CRM genes were downregulated. However, under drought and cold stress, the expression level of some CRM genes was increased. The analysis of gene expression patterns showed that 14 CRM genes were expressed in all tissues but especially highly expressed in leaves. In addition, we analyzed the functions of OsCFM2 and found that this protein influences chloroplast development by regulating the splicing of a group I and five group II introns. Our study provides information for the function analysis of CRM domain-containing proteins in rice.
