DREB
DREB, which stands for Dehydration Responsive Element Binding, is a family of transcription factors found in plants. These proteins play a crucial role in the plant's response to drought stress and other environmental challenges. DREB proteins bind to specific DNA sequences known as dehydration-responsive elements (DREs) or C-repeat elements (CRT), which are found in the promoter regions of many stress-inducible genes.
The primary function of DREB transcription factors is to regulate the expression of genes involved in stress
There are different types of DREB proteins, broadly categorized into DREB1 and DREB2 subgroups. DREB1 proteins
