Transcription Factor: A Master Regulator Under Heat Stress

Abstract

Heat stress is a major abiotic stress that slower down plant growth and development worldwide. Plant growth involves various metabolic reactions that are very sensitive to heat stress. Heat stress is now a major concern for world food production. Plant Respond to such adverse effect by various ways which are interconnected by a network of transcription factor, including heat responsive transcription factor (HSF). HSFs plays an important role in plant response to heat stress by regulating the expression of stress associated genes including heat shock proteins (Hsps) and antioxidant enzymes. In this review, I have described the structure of plant heat shock transcription factor, their gene family from various plant species. Though HSF shares some common structure but they are highly diversified and this is also reflected in their function.
