bZIP transcription factors in Arabidopsis.
In plants, basic region/leucine zipper motif (bZIP) transcription factors regulate processes including pathogen defence, light and stress signalling, seed maturation and flower development. The Arabidopsis genome sequence contains 75 distinct members of the bZIP family, of which approximately 50 are not described in the literature. Using common domains, the AtbZIP family can be subdivided into ten groups. Here, we review the available data on bZIP functions in the context of subgroup membership and discuss the interacting proteins. This integration is essential for a complete functional characterization of bZIP transcription factors in plants, and to identify functional redundancies among AtbZIP factors.
