Abstract
Molecular and genomic studies have shown that several genes with various functions
are induced by drought and cold stresses, and that various transcription factors are
involved in the regulation of stress-inducible genes. The products of stress-inducible
genes function not only in stress tolerance but also in stress response. Genetic studies
have identified many factors that modify the regulation of stress responses. Recent
progress has been made in analyzing the complex cascades of gene expression in drought
and cold stress responses, especially in identifying specificity and crosstalk in
stress signaling.
