碱性螺旋―环―螺旋（basic helix-loop-helix，bHLH）转录因子作为植物中第二大类转录因子家族，在植物生长发育、信号传导、生物合成以及响应非生物胁迫等方面发挥重要功能。

2025年2月1日 · The basic helix loop helix (bHLH) gene family plays an important role in the biosynthesis of plant anthocyanins. However, there was no research on the ChbHLH gene family in C. humilis. In this study, 114 ChbHLH genes were identified from the C. humilis genome and divided into 17 subgroups. Then, evolutionary relationships, conserved motifs ...

2024年6月1日 · Simplified representation of the basic helix-loop-helix (bHLH) regulatory network that controls iron homeostasis in arabidopsis (Arabidopsis thaliana). Eighteen different bHLH transcription factors from seven subfamilies (i.e., Ib, IIIa, IIIe, IIIf, IVa, IVb, and IVc) act within an intricate regulatory network to regulate iron homeostasis.

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.

bHLH 作为植物 体内第二大类转录因子，能与E-box 顺式作用元件特异性结合，调控胁迫- 应答相关基因的表达。侧重对 植物中bHLH 转录因子参与非生物胁迫信号通路的最新研究进展进行综述，以期进一步了解植物bHLH 转

2024年5月7日 · Several bodies of research have shed light on the pleiotropic functions of BASIC HELIX-LOOP-HELIX (bHLH) proteins in plant responses to these abiotic stresses. In this review, we mention the regulatory roles of bHLH TFs in response to stresses such as cold, drought, salt resistance, and iron deficiency, as well as in enhancing grain yield in ...

2023年7月5日 · 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.

bHLH转录因子，即碱性螺旋—环—螺旋（basic helix-loop-helix，bHLH）蛋白，是广泛存在于植物、动物和真菌中的转录因子超家族之一。bHLH超家族成员含有2个高度保守且功能不同的结构域：碱性区域（basic region）和螺旋—环—螺旋（helix-loop-helix，HLH）区域。

bHLH转录因子是植物中最大的转录因子家族之一。 为深入了解植物bHLH转录因子的功能和结构特点，本文总结了bHLH转录因子的结构特点，并阐述植物bHLH转录因子在光信号转导、激素合成、腺毛和根毛发育及逆境胁迫中的功能。

2021年10月31日 · In this study, 183 HabHLH genes were identified and named according to their chromosomal locations. We classified these proteins into 21 subfamilies by phylogenetic tree analysis. Subsequently, DNA-binding patterns, sequence analysis, duplication analysis and gene structures were analyzed.
