O-glycosylation regulates plant developmental transitions downstream of miR156

Abstract: The timing of plant developmental transitions is decisive for reproductive success and thus tightly regulated by a number of pathways with a high degree of crosstalk between them. Such complex regulatory pathways often involve post-translational modifications (PTMs), integrating internal and environmental signals. O-glycosylation, the attachment of a single monosaccharide to serine or threonine of nuclear and cytosolic proteins, is one of these PTMs, affecting a number of very diverse proteins. Here we show th… Show more

“…This is supported by the fact that low sugar availability prevents the transition to the adult phase through high levels of miR156, and sugar supply represses the expression of MIR156 genes [ 425 , 426 ]. It is interesting that mutants in the OFT SPY show accelerated developmental transitions, related to the O-glycosylation of transcription factors acting downstream of miR156 [ 427 ]. This supports the idea that T6P/SnRK1 signaling might be altered by glycosylation events.…”
