Mar 15, 2023 · Basic helix–loop–helix (bHLH) proteins belong to one of the largest families involved in plant growth, development, signal transduction, and secondary metabolism. Although bHLH genes have been previously identified in persimmon (Diospyros kaki), systematic studies have not been reported.

Jun 1, 2024 · Basic helix-loop-helices (bHLHs) form one of the largest families of transcription factors (TFs) found in plants. bHLHs function as transcriptional activators and/or repressors. bHLHs function in complex regulatory networks to regulate various biological and …

In this review, we summarize the available knowledge on functionally characterized bHLH transcription factors according to four categories: plant growth and development; metabolism synthesis; plant signaling, and abiotic stress responses.

Jul 1, 2021 · In this review, we summarize various aspects of related studies that provide an overview of insights into the pleiotropic regulatory roles of these transcription factors in plant growth and development, stress response, biochemical functions and the web of …

The basic helix-loop-helix (bHLH) transcription factor family is one of the largest transcription factor gene families in Arabidopsis thaliana, and contains a bHLH motif that is highly conserved throughout eukaryotic organisms. Members of this family have two conserved motifs, a basic DNA binding region and a helix-loop-helix (HLH) region.

Feb 15, 2023 · Here, we summarize the structure, classification and regulation of bHLH TFs, and focused on the function and regulatory mechanisms of key bHLH TFs in the abiotic stress response of horticultural crops.

Jun 18, 2021 · Basic helix-loop-helix proteins (bHLHs) comprise one of the largest families of transcription factors in plants. They have been shown to be involved in responses to various abiotic stresses, such as drought, salinity, chilling, heavy metal toxicity, iron deficiency, and osmotic damages.

May 6, 2021 · Named for the characteristic basic helix-loop-helix (bHLH) region in their protein structure, bHLH proteins are a widespread transcription factor class in eukaryotes. bHLHs transcriptionally regulate their target genes by binding to specific positions on their promoters and thereby direct a variety of plant developmental and metabolic processes,...

Jul 5, 2023 · We set out to address how different classes of bHLH TFs, MYC-MAX and CLOCK-BMAL1, together with an unrelated TF, OCT4, structurally and functionally interact with nucleosomes.

Recent completion of whole genome sequences of model plants Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa) allows genome-wide analysis and comparison of the bHLH family in flowering plants.
