Novel factors involved in land plant spermatogenesis identified

August 5, 2022

New functions that basal body protein acquired

A collaborative research team, including Meiji University, the National Institute for Basic Biology, Kanazawa University, Rikkyo University, and the RIKEN CSRS, identified BLD10s, novel factors involved in spermatogenesis in liverworts, by screening omics data. Furthermore, they suggested that the functions of the BLD10 genes in spermatogenesis could be newly acquired during the molecular evolution of the BLD10 genes in addition to its ancestral functions.

The screening of this study has selected other candidate factors involved in spermatogenesis other than the BLD10 genes. By analyzing the functions of these candidates, more factors related to spermatogenesis might be further identified.
