The diversity of plant heat stress transcription factors

Trends Plant Sci. 2007 Oct;12(10):452-7. doi: 10.1016/j.tplants.2007.08.014. Epub 2007 Sep 7.


Compared with other eukaryotes with one to three heat stress transcription factors (Hsf), the plant Hsf family shows a striking multiplicity, with more than 20 members. Despite many conserved features, members of the Hsf family show a strong diversification of expression pattern and function within the family. Research on Arabidopsis Hsfs opened a new era with genome-wide transcriptome profiling in combination with the availability of knockout lines. The output from these analyses provides increasing evidence that individual Hsfs have unique functions as part of different signal transduction pathways operating in response to environmental stress and during development.
