bHLH transcription factor bHLH115 regulates iron homeostasis in Arabidopsis thaliana [PDF]

Journal of Experimental Botany, 2017
Iron (Fe) deficiency is a limiting factor for the normal growth and development of plants, and many species have evolved sophisticated systems for adaptation to Fe-deficient environments. It is still unclear how plants sense Fe status and coordinate the expression of genes responsive to Fe deficiency.

The subcellular localization of bHLH transcription factor TCF4 is mediated by multiple nuclear localization and nuclear export signals

Scientific Reports, 2019
Transcription factor 4 (TCF4) is a class I basic helix-loop-helix (bHLH) transcription factor which regulates the neurogenesis and specialization of cells.

bHLH Ib transcription factors regulate the transcription of FIT in Arabidopsis thaliana

Guangxi Zhiwu, 2023
FIT (FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR) is a key regulator of Fe homeostasis in Arabidopsis, which is upregulated under Fe deficiency condition, however, the underlying regulatory mechanism is still unclear.

Control of Precerebellar Neuron Development byOlig3bHLH Transcription Factor [PDF]

The Journal of Neuroscience, 2008
The rhombic lip (RL) is the neuroepithelium immediately adjacent to the roof plate of the fourth ventricle, and it gives rise to various brainstem and cerebellar cell types. Our study shows that the bHLH (basic helix-loop-helix) transcription factorOlig3is expressed in the progenitors of RL, and ablation ofOlig3significantly affects the development of ...

Irreversible fate commitment in the Arabidopsis stomatal lineage requires a FAMA and RETINOBLASTOMA-RELATED module

eLife, 2014
The presumed totipotency of plant cells leads to questions about how specific stem cell lineages and terminal fates could be established. In the Arabidopsis stomatal lineage, a transient self-renewing phase creates precursors that differentiate into one ...

Comparative genomic analysis of bHLH genes across multiple species uncovers a novel gene regulating ginsenoside biosynthesis in Panax ginseng

BMC Plant Biology
Background Basic helix–loop–helix (bHLH) transcription factors are the second largest transcription factor family in plants and regulate diverse physiological processes.

Murine Chromosomal Location of Five bHLH-Zip Transcription Factor Genes

Genomics, 1995
The genes for the bHLH-Zip transcription factors Tfap4, Mxi1, Tcfeb, Usf1, and Usf2 have been mapped in mouse by interspecific backcross analysis. Mxi1, Usf1, and Usf2 have been mapped previously by in situ hybridization, but their positions on the meiotic linkage map had not been determined. The other two genes have not previously been mapped in mouse.

Evolutionary and comparative analysis of MYB and bHLH plant transcription factors [PDF]

The Plant Journal, 2011
SummaryThe expansion of gene families encoding regulatory proteins is typically associated with the increase in complexity characteristic of multi‐cellular organisms. The MYB and basic helix‐loop‐helix (bHLH) families provide excellent examples of how gene duplication and divergence within particular groups of transcription factors are associated with,

Identification and in silico characterization of soybean trihelix-GT and bHLH transcription factors involved in stress responses

Genetics and Molecular Biology, 2012
Environmental stresses caused by either abiotic or biotic factors greatly affect agriculture. As for soybean [Glycine max (L.) Merril], one of the most important crop species in the world, the situation is not different.

MYB transcription factor PdMYB118 directly interacts with bHLH transcription factor PdTT8 to regulate wound-induced anthocyanin biosynthesis in poplar

BMC Plant Biology, 2020
Background R2R3-MYB transcription factors (TFs) play important roles in plant growth and development, and response to biotic and abiotic stresses. However, their regulatory mechanisms in wound-induced anthocyanin biosynthesis in woody plants are largely ...
