Genome-wide identification of five fern bHLH families and functional analysis of bHLHs in lignin biosynthesis in Alsophila spinulosa.

ABSTRACT:

Background

The basic helix-loop-helix (bHLH) transcription factors are involved in the biosynthesis of various secondary metabolites. However, genome-wide studies on the bHLH gene family in ferns and their role in lignin biosynthesis remain limited. As the second largest group of vascular plants, ferns are of significant interest for understanding plant evolution and secondary metabolism. Among ferns, Alsophila spinulosa stands out as one of the few tree ferns with a distinctive trunk structure. Investigating the genes potentially regulating lignin biosynthesis in A. spinulosa offers valuable insights into the growth and development mechanisms of its trunk, which is pivotal for the overall architecture and function of the plant.
