Mp2g04160 MpBHLH35 experimental subject Subfamily Ia bHLH TF (named MpSETA by Moriya et al., MpSMF by Chang et al.). Knockout abolished elongated setal cells, promoter active in developing setal region, and it interacts with ICE1/SCRM. Concluded to be a pivotal regulator of sporophytic setal development; can partially rescue Arabidopsis mute.
Mp4g04920 MpICE2 experimental subject M. polymorpha ICE1/SCRM ortholog and heterodimerization partner of MpSETA/MpSMF. Knockout showed defective setal development, supporting conserved SMF-ICE1/SCRM heterodimerization in liverworts.
