Associated Literature (AI-based literature mining, Beta-version)

RSL class I bHLH transcription factor; loss-of-function mutants failed to make rhizoids, slime/mucilage papillae and gemmae, while gain-of-function lines produced ectopic rhizoids, and complementation restored development. Expressed in rhizoids, gemmae and ventral thallus, highest in cells expanding out of the epidermis; can replace AtRHD6 in Arabidopsis, showing conserved control of epidermal structures.

The rhizoid-specific transcription factor RSL1 (MpRSL1) is the local activator in the patterning model; mathematical modeling combining published and original data shows rhizoid patterning is consistent with local RSL1 activation modulated by lateral inhibition, reproducing wild-type and mutant spatial statistics.

RSL transcription factor; interacts with MpSACL to regulate gemma and rhizoid production.
Thamm, A., et al. (2019) · BioRxiv  research experimental subject
RSL class I bHLH activator of rhizoid cell fate; its mRNA is repressed by MpFRH1; gain-of-function increases rhizoids — the activator in the lateral-inhibition module.
Honkanen, S., et al. (2018) · eLIFE  research experimental subject
Shown by RLM-RACE to be the direct cleavage target of MpFRH1 miRNA, with reduced steady-state mRNA in all four MpFRH1GOF mutants. A miRNA-resistant MpRSL1res restored rhizoid/gemma development (88.9% vs 0%), and MpRSL1 positively feeds back on MpFRH1, forming a negative-feedback regulatory loop.
