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 کاملA triple helix-loop-helix/basic helix-loop-helix cascade controls cell elongation downstream of multiple hormonal and environmental signaling pathways in Arabidopsis.
Environmental and endogenous signals, including light, temperature, brassinosteroid (BR), and gibberellin (GA), regulate cell elongation largely by influencing the expression of the paclobutrazol-resistant (PRE) family helix-loop-helix (HLH) factors, which promote cell elongation by interacting antagonistically with another HLH factor, IBH1. However, the molecular mechanism by which PREs and IB...
متن کاملID helix-loop-helix proteins
The helix-loop-helix (HLH) family of transcription factors comprises >200 members, which have been identified in organisms from yeast to man (reviewed in Littlewood and Evan, 1995; Massari and Murre, 2000). In metazoa, HLH proteins function in the coordinate regulation of gene expression, orchestrating cell cycle control, cell lineage commitment and cell differentiation. An essential role has b...
متن کاملA triantagonistic basic helix-loop-helix system regulates cell elongation in Arabidopsis.
In plants, basic helix-loop-helix (bHLH) transcription factors play important roles in the control of cell elongation. Two bHLH proteins, PACLOBTRAZOL RESISTANCE1 (PRE1) and Arabidopsis ILI1 binding bHLH1 (IBH1), antagonistically regulate cell elongation in response to brassinosteroid and gibberellin signaling, but the detailed molecular mechanisms by which these factors regulate cell elongatio...
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...
