Special issue: Orchestrating the proteome with post-translational modifications I guess we’re well past the stage of thinking “one gene – one protein”, but even a single polypeptide isn’t really one protein, due to the huge number of different types of post-translational modification (PTM) it can be subjected to. These are summarized in the illustration that […]

How chloroplasts remain viable inside of herbivorous sea slugs is a long-standing curiosity. Unlike corals, which host intact photosynthetic algae, sea slugs retain naked chloroplasts (which are then called kleptoplasts – stolen plastids), some of which remain viable for seveal weeks. Christa et al. explored how kleptoplasts from diverse algal species survive without the support […]
Martinez et al. used a modelling approach to see if it is possible to predict the location of a cell’s future division plane. In most cases the cell divides according to strict geometric rules, such that the newly formed wall will have a minimum area (described as a soap-film minimization model). However, in some cases […]
Ploidy refers to the number of genomes contained within a nucleus. Ploidy levels can increase through whole-genome duplication, which affects every cell equally, and through endoreduplication, a cell-by-cell process in which DNA synthesis is not accompanied by cytokinesis. Robinson et al. investigated how increasing ploidy (both types) affects nuclear, cell and organ size. They found […]
By now we’re probably all familiar with the central dogma of auxin signalling; that the interaction between auxin and auxin receptors (e.g., TIR1) leads to degradation of Aux/IAA proteins, freeing up ARF transcription factors to do their things. The complexity of this simple system arises in part due to the large numbers of all of […]
