Area of Science:

  • Plant molecular biology
  • Gene regulation
  • Stress physiology

Context:

  • DREB transcription factors are key regulators of plant responses to abiotic stress.
  • They bind to DRE/CRT cis-acting elements in the promoters of stress-inducible genes.
  • Understanding DREB function is crucial for improving crop resilience.

Purpose:

  • To elucidate the relationship between DREB transcription factors and DRE/CRT cis-acting elements.
  • To detail the functional, structural, expression, and regulatory characteristics of DREBs.
  • To review recent advancements in DREB gene cloning and identification.

Summary:

  • DREB transcription factors specifically bind to DRE/CRT cis-acting elements, regulating numerous stress-inducible genes.
  • This interaction enhances plant tolerance to environmental stressors like drought, low temperature, and high salinity.
