Mp5g06470 MpESV1 missing experimental comparator Marchantia ESV1 ortholog (74% aa identity to AtESV1) expressed under the endodermis-specific SCR promoter in an Arabidopsis esv1-2 mutant; it rescued endodermal starch granule formation and hypocotyl negative gravitropism in darkness, with red light still inhibiting both, used as cross-species evidence that ESV1 function is conserved from liverworts to angiosperms.
