The type B Arabidopsis Response Regulators (ARRs) of Arabidopsis thaliana are transcription factors that act as positive regulators in the two-component cytokinin signaling pathway. We employed a mutant-based approach to perform a detailed characterization of the roles of ARR1, ARR10, and ARR12 in plant growth and development. The most pronounced phenotype(More)
With a completely reengineered and humanized glycosylation pathway, glycoengineered Pichia pastoris has emerged as a promising production host for the manufacture of therapeutic glycoproteins. However, the extensive genetic modifications have also negatively affected the overall fitness levels of the glycoengineered host cells. To make glycoengineered(More)
Protein O-mannosyltransferases (PMTs) catalyze the initial reaction of protein O-mannosylation by transferring the first mannose unit onto serine and threonine residues of a nascent polypeptide being synthesized in the endoplasmic reticulum (ER). The PMTs are well conserved in eukaryotic organisms, and in vivo defects of these enzymes result in cell death(More)
