Effects of Tissue-specific Expression of FHY3 on Cell Death of fhy3far1 in Arabidopsis Thaliana

摘要(Abstract):

为了探究植物光信号蛋白FHY3及其同源蛋白FAR1在叶片细胞死亡调控过程中的分子机制,在拟南芥fhy3far1双突变体背景下分别在维管束及叶肉细胞中表达FHY3。结果表明:在fhy3far1双突变体维管束中特异性表达FHY3可完全改善fhy3far1的细胞死亡表型,而在fhy3far1双突变体叶肉细胞中特异性表达FHY3仅可部分缓解fhy3far1叶片细胞死亡表型,揭示了FHY3调控细胞死亡过程主要是在维管束中行使功能。
