Transcription factors in plant growth and development.
The target DNA sequences of several classes of plant transcription factors, including basic leucine zipper (bZIP) proteins and Myb-related factors, have been characterized in vivo as well as in vitro. The bZIP proteins, for example, act at ACGT elements, the flanking nucleotides determining their binding specificities. Overexpression, co-suppression, and antisense technology studies of factor genes in transgenic plants have uncovered the roles of bZIP, homeodomain, and MADS box factors in plant growth and development; for example, ectopic expression of pMADS1 alone in early Petunia development is sufficient for homeotic conversion of sepals into petaloid organs.
