Resumen:
The
knowledge about the role of transcription factors in the eukaryotic domain,
mainly in yeast, Drosophila, human, and later in plants, significantly advanced
since the first discovery of these regulatory proteins in prokaryotes, fifty
years ago. Transcription factors are involved in a variety of biological
processes including the responses to environmental changes. In this review, we
focus on plant transcription factors involved in the responses to abiotic
stresses, mainly drought and salinity. We analyze the modular structure that
characterizes common and kingdom-specific groups or families and the main
environmental stimuli that modulate the responses through different signaling
pathways. Thereafter, we review examples of the roles played by transcription
factors in classical breeding approaches for crop improvement. Finally, we
revise the discovery, characterization and use of transcription factors as
biotechnological tools. About the last point, we discuss the experimental
methods and parameters adopted to evaluate tolerant phenotypes and the apparent
dilemma between crops yield and stress tolerance.
