The Arabidopsis basic/helix-loop-helix transcription factor family.
The basic/helix-loop-helix (bHLH) proteins are a superfamily of transcription factors that bind as dimers to specific DNA target sites and that have been well characterized in nonplant eukaryotes as important regulatory components in diverse biological processes. Based on evidence that the bHLH protein PIF3 is a direct phytochrome reaction partner in the photoreceptor's signaling network, we ha...
متن کاملUpdate on the basic helix-loop-helix transcription factor gene family in Arabidopsis thaliana.
Basic helix-loop-helix (bHLH) transcription factors represent a family of proteins that contain a bHLH domain, a motif involved in binding DNA. Recently, two groups independently analyzed the BHLH gene family of Arabidopsis thaliana (Heim et al., 2003; Toledo-Ortiz et al., 2003). These analyses revealed that this family is one of the largest transcription factor gene families in Arabidopsis tha...
متن کاملGenome-wide analysis of basic/helix-loop-helix transcription factor family in rice and Arabidopsis.
The basic/helix-loop-helix (bHLH) transcription factors and their homologs form a large family in plant and animal genomes. They are known to play important roles in the specification of tissue types in animals. On the other hand, few plant bHLH proteins have been studied functionally. Recent completion of whole genome sequences of model plants Arabidopsis (Arabidopsis thaliana) and rice (Oryza...
متن کاملDifferentiation of Arabidopsis guard cells: analysis of the networks incorporating the basic helix-loop-helix transcription factor, FAMA.
Nearly all extant land plants possess stomata, the epidermal structures that mediate gas exchange between the plant and the environment. The developmental pathways, cell division patterns, and molecules employed in the generation of these structures are simple examples of processes used in many developmental contexts. One specific module is a set of "master regulator" basic helix-loop-helix tra...
متن کاملObligate Heterodimerization of Arabidopsis Phytochromes C and E and Interaction with the PIF3 Basic Helix-Loop-Helix Transcription Factor W
Phytochromes are dimeric chromoproteins that regulate plant responses to red (R) and far-red (FR) light. The Arabidopsis thaliana genome encodes five phytochrome apoproteins: type I phyA mediates responses to FR, and type II phyB–phyE mediate shade avoidance and classical R/FR-reversible responses. In this study, we describe the complete in vivo complement of homodimeric and heterodimeric type ...
