以前的研究表明，至少有两个转录因子HY5和GLK2参与了关键的叶绿素和光合作用基因的共表达网络，但它们不足以实现光系统的全功能组装。为了探索其转录机制，我们在此克隆了编码核转录因子的基因，这些基因在拟南芥绿色的根中被诱导。进一步的表达分析表明，这些因子的表达不依赖于依赖于HY5和GLK的信号通路。为了弄清基因表达网络，有必要对参与叶绿体分化的这些转录因子进行进一步分析。
Previous studies showed that at least two transcription factors, HY5 and GLK2, were involved in the co-expression network of key chlorophyll and photosynthesis genes, but they were not sufficient for fully functional photosystem assembly. To explore the transcriptional mechanism, here genes encoding nuclear transcription factors were identified, which were induced in greenish roots ofArabidopsis. Further expression analysis suggested that the expression of these factors was independent from HY5– and GLK–dependent signaling pathways. To clarify the gene expression network, further analysis of such transcription factors involved in chloroplast differentiation will be necessary.
