The bZIP family is one of the most widely distributed and conserved
transcription factor categories in eukaryotes. They are widely involved
in processes of plant abiotic stress responses, such as improving the
ability of plants to adapt to drought, salinity and cold. To
comprehensively understand how plant bZIPs regulating these tolerances,
this article will have an overview of their distributions on different
species, characteristics of protein architecture, regulation mechanisms
for target genes' transcriptional expression, and relevant research
progresses in recent years. Specially, we will discuss the possible
roles of flavonoids, whose synthesis could be regulated by bZIPs, in
abovementioned plant tolerant responses.
