AtbZIP16 integrates light and hormone signaling pathways to regulate Arabidopsis early seedling development

ABSTRACT: In response to environmental light signals, transcriptomic adjustment plays an important role in Arabidopsis seed germination and seedling development. G-box cis-element is commonly present in promoters of genes positively or negatively responding to the light signal. For the pursuit of additional transcriptional regulator modulating light-mediated transcriptome changes, we have identified AtbZIP16, a basic region/leucine zipper motif transcription factor, via G-box DNA affinity chromatography. We have confirmed that AtbZIP16 possesses G-box-specific binding activity. Analyses of atbzip16 mutants indicate that AtbZIP16 is a negative regulator in phyB-mediated inhibition of cell elongation, but a positive regulator in phytochrome-mediated seed germination process.
