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 …

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.

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.

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.

In this review, we describe how all these mechanisms have a role and crosstalk in one specific family of TFs, the basic helix-loop-helix (bHLH), with a very conserved DNA binding domain and a similar DNA preferred motif, the E-box.

Dec 7, 2016 · Here, we first discuss the bHLH TFs involved in all kinds of JA-modulated processes in the model plant Arabidopsis thaliana. Secondly, we elaborate on the identity and role of bHLH TFs in the conserved JA-mediated elicitation of …

Feb 15, 2023 · The bHLH family is one of the largest transcription factor (TF) families in plants, playing important roles in many different response pathways of diverse abiotic stresses, such as water deficit, high salinity, low temperature, and nutrient deficiencies.

Nov 16, 2021 · Here, we characterized the function of a bHLH TF in the peanut, AhHLH112, in response to drought stress. AhHLH112 is localized in the nucleus and it was induced by drought stress. The overexpression of this gene improves the drought tolerance of transgenic plants both in seedling and adult stages.

Mar 2, 2015 · These elaborated strategies rely on rapid and precise gene regulation mediated by transcription factors (TFs). TFs represent a large fraction of plant genomes and among them, MYBs and basic helix-loop-helix (bHLHs) have unique inherent properties specific to plants.

Basic helix-loop-helices (bHLHs) are present in all eukaryotes and form one of the largest families of transcription factors (TFs) found in plants. bHLHs function as transcriptional activators and/or repressors of genes involved in key processes involved in plant growth and development in interaction with the environment (e.g., stomata and root ...
