MXL proteins repress moss growth through a conserved ancestral signaling pathway

Guillory et al. explore the role of SMXL proteins in Physcomitrium patens growth.  https://doi.org/10.1093/plcell/koae009  By Ambre Guillory, Sandrine Bonhomme and Catherine Rameau Background: In flowering plants, several proteins of the SUPPRESSOR OF MAX2 1-LIKE (SMXL) family influence the…

Co-evolution of the RNA editing factor PPR78 and its targets

Lesch et al. reveal that the mitochondrial RNA editing factor PPR78 of Physcomitrium patens is conserved among mosses despite the loss of its two known C-to-U editing sites due to the additional editing target ccmFNeU1465RC.  https://doi.org/10.1093/plcell/koad292 By Elena Lesch, Volker Knoop…

Isoform specificity in plant COPII gene families

Chang et al. discover the phenotypic consequences of different isoforms of Coat Protein Complex II genes in the moss Physcomitrium patens. Background: Vesicles that form on the endoplasmic reticulum (ER) and are bound for the Golgi apparatus are coated in a complex of proteins known as Coat Protein…
