Abstract:Plants possess well-developed light sensing mechanisms and signal transduction systems for regulating photomorphogenesis. ELONGATED HYOCOTYL 5 (HY5), a basic leucine zipper transcription factor, has been extensively characterized in dicot plants. In this study, we have shown thatOsbZIP1is a functional homolog ofArabidopsis HY5 (AtHY5)and is important for light-mediated regulation of seedling and mature plant development in rice. Ectopic expression ofOsbZIP1in rice reduces plant height and leaf length without a… Show more
