Isolation and expression analysis of a candidate gametophyte sex determination gene (sjhmg) of kelp (Saccharina japonica)

Saccharina japonica undergoes an alternating life cycle during which the diploid sporophyte generation alternates with the happloid gametophyte generation. Saccharina japonica uses the UV sex determination system to determine the sex of its haploid gametophytes. However, the sex‐determining genes and the sex‐determining mechanisms of kelp gametophytes have not been thoroughly elucidated to date. In this study, a kelp HMG ‐box‐containing gene (...
