Abstract

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 zinc-fingers (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. A total of 39 genes are up-regulated more than 2-fold, in comparison to vegetative stages, during reproductive development of rice, out of which 18 are specific to panicle development and 12 genes are seed-specific. Twenty-six genes have been found to be up-regulated during three abiotic stresses and of these, 14 genes express specifically during the stress conditions analyzed while 12 are also up-regulated during reproductive development, suggesting that some components of the stress response pathways are also involved in reproduction.
