Area of Science:

  • Plant Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • Gene expression in plants is primarily controlled by transcription factors binding to specific DNA sequences.
  • Numerous plant transcription factors have been identified through various screening methods.
  • These factors often belong to families with conserved DNA-binding domains and can form complexes.

Purpose of the Study:

  • To review and synthesize current knowledge on plant transcription factors.
  • To elucidate the mechanistic aspects of transcriptional regulation in plants.
  • To provide a comprehensive overview for researchers in the field.

Main Methods:

  • Literature review of studies on plant transcription factor identification and characterization.
  • Analysis of data on transcription factor families, DNA-binding specificities, and dimerization.
  • Summary of regulatory mechanisms including post-translational modifications and nuclear transport.

Main Results:

  • Plant transcription factors exhibit diverse structures and DNA-binding specificities.
  • Dimerization (homo- and hetero-) expands the range of recognized DNA sequences.
  • Regulation involves modular activation domains and post-translational modifications.

Conclusions:

  • Understanding plant transcription factors is crucial for deciphering gene expression control.
  • Post-translational modifications and nuclear transport are key regulatory points.
  • This review consolidates current insights into plant transcriptional regulation.
