Genome-wide analysis of MpBHLH12, a IIIf basic helix-loop-helix transcription factor of Marchantia polymorpha.

ABSTRACT: The evolution of plants on land required adaptation to UV radiation and dry environments, and involved the appearance and/or rewiring of genetic connections, known as gene regulatory networks (GRNs), which consist of one or more transcription factors (TFs). The liverwort, Marchantia polymorpha, is a basal land plant, with a recently sequenced genome. The number of genes encoding basic helix-loop-helix (bHLH) family members is considerably higher in M. polymorpha than in charophyte green algae, suggesting the contribution of bHLH proteins to the evolution of GRNs associated with the adaptation of plants to land. Although an understanding of the evolutionary aspects of GRNs is fundamental for elucidating the mechanisms of environmental adaptation, the evolution of GRNs that led to land adapt
