Functional analysis of the rice rubisco activase promoter in transgenic Arabidopsis

► Rice rubisco activase promoter was analyzed in transgenic Arabidopsis system. ► Region conferring tissue specific and light inducible expression of Rca was identified. ► −58 to +43 bp region mediates tissue-specific expression of rice Rca. ► Light inducible expression of rice Rca is mediated by −297 to −58 bp region. ► Rice nuclear proteins bind specifically with the light inducible region.
