核基因突变引起的拟南芥菜叶片花斑及其机制

Variegation and Its Mechanism in Arabidopsis Leaves Induced by Mutation of Nuclear Genes

细胞核基因突变引起的植物叶片花斑,是研究细胞器(特别是叶绿体)和细胞核之间信息交流的重要材料,也在园艺科学上有重要的应用价值。综述了拟南芥菜IM、VAR1、VAR2、CHM、CUE1、PAC、ATD2和VAR3等8个细胞核基因突变后引起的叶片花斑,主要包括这些基因所编码的蛋白质以及它们突变以后引起花斑的机制。

Variegation induced by mutation in nuclear genes is a powerful tool to study interactions between organelle （especially the chloroplast） and nucleus. It is also of great interests for horticultural sciences. Leaf variegation resulted from mutation of 8 Arabidopsis nuclear genes, IMMUTANS, VAR1, VAR2, CHM, CUE1, PAC, ATD2 and VAR3, has been reviewed. Proteins encoded by these genes and variegation mechanisms related to these genes were presented.
