The degradation of plasma membrane and other membrane-associated proteins require their sorting at endosomes for delivery to the vacuole. Through the endocytic pathway, ubiquitinated membrane proteins (cargo) are delivered to endosomes where the ESCRT (endosomal sorting complex required for transport) machinery sorts them into intralumenal vesicles for degradation. Plants contain both conserved and plant-specific ESCRT subunits. In this review, I discuss the role of characterized plant ESCRT components, the evolutionary diversification of the plant ESCRT machinery, and a recent study showing that endosomal intralumenal vesicles form in clusters of concatenated vesicle buds by temporally uncoupling membrane constriction from membrane fission.

The structure of a Nucleosome, in which DNA is wrapped around a histone core. In this issue of Biochemical Society Transactions, Taniguchi et al. review recent advances in exploring Nucleosome-level 3D organization of the genome; for details see pages 491–501.
