Innovations and stepwise evolution of CBFs/DREB1s and their regulatory networks in angiosperms OO
文献摘要：
The C-repeat binding factors/dehydration-responsive element binding protein 1s (CBFs/DREB1s) have been identified as major regulators of cold acclimation in many angiosperm plants. How-ever, their origin and evolutionary process asso-ciated to cold responsiveness are still lacking. By integrating multi-omics data of genomes, tran-scriptomes, and CBFs/DREB1s genome-wide binding profiles, we unveil the origin and evolution of CBFs/DREB1s and their regulatory network. Gene collinearity and phylogeny analyses show that CBF/ DREB1 is an innovation evolved from tandem duplication-derived DREB Ⅲ gene. A subsequent event ofε-whole genome duplication led to two CBF/DREB1 archetypes (Clades I and Ⅱ) in ancient an-giosperms. In contrast to cold-insensitivity of Clade I and their parent DREB Ⅲ genes, Clade Ⅱ evolved a further innovation in cold-sensitive response and was stepwise expanded in eudicots and monocots by independent duplications. In geological time, the duplication events were mainly enriched around the Cretaceous–Paleogene (K–Pg) boundary and/or in the Late Cenozoic Ice Age, when the global average temperature significantly decreased. Consequently, the duplicated CBF/DREB1 genes contributed to the rewiring of CBFs/DREB1s-regulatory network for cold tolerance. Altogether, our results highlight an origin and convergent evolution of CBFs/DREB1s and their regulatory network probably for angio-sperms adaptation to global cooling.
