Functional interaction between two transcription factors involved in the developmental regulation of a small heat stress protein gene promoter.

Plant physiology - 1 Nov 2005

Díaz-Martín Juan, Almoguera Concepción, Prieto-Dapena Pilar, Espinosa José M, Jordano Juan

Abstract excerpt

Hahsp17.6G1 is the promoter of a small heat stress protein (sHSP) from sunflower (Helianthus annuus) that is activated during zygotic embryogenesis, but which does not respond to heat stress. We report here the cloning of a transcription factor (TF), sunflower drought-responsive element binding factor 2 (HaDREB2), by one-hybrid interaction with functional cis-elements in Hahsp17.6G1. We have analyzed the...
