Transcription factors regulate gene expression in response to various external and internal cues by activating
or suppressing downstream genes in a pathway. In this study, we provide a complete overview of the genes
encoding C2H2 zinc-finger transcription factors in rice, describing the gene structure, gene expression, genome localization, and phylogenetic relationship of each member. The genome of Oryza sativa codes for 189 C2H2 zinc-finger transcription factors, which possess two main types of zincfingers (named C and Q). The Q-type zinc fingers contain a conserved motif, QALGGH, and are plant specific, whereas C type zinc fingers are found in other organisms as well. A genome-wide microarray based gene expression analysis
involving 14 stages of vegetative and reproductive development along with 3 stress conditions has revealed that C2H2 gene family in indica rice could be involved during all the stages of reproductive development from panicle initiation till seed maturation. |
