摘要：

A light-regulated basic domain/leucine zipper gene, ATB2, was identified in an Arabidopsis thaliana transcription factor gene collection. Both genomic and cDNA clones of ATB2 were isolated. The gene encodes a small protein (18 kDa) which mainly consists of the basic domain and an unusually long leucine zipper. The expression of the ATB2 gene is induced when etiolated or dark-adapted seedlings are transferred to the light. Moreover, its expression is derepressed in dark-grown seedlings of the photomorphogenic mutants cop1 and det1. In mature plants, transcript levels are particularly high in flowers and also light-responsive in these tissues.
