A Lipid Droplet-Associated Degradation System in Plants
The Plant Cell, The Plant Cell: In BriefOnce viewed merely as inert packets of metabolic energy that are mobilized during postgerminative growth, lipid droplets (LDs) have emerged as dynamic organelles with important roles in processes ranging from stress responses to hormone signaling (Pyc et al., 2017). LDs consist of a core of neutral lipids…
Tic-Tac-Toe: How TIC and TOC Coordinate Getting Proteins Across the Line
The Plant Cell, The Plant Cell: In BriefMost proteins within a cell are encoded in the nucleus and then translated in the cytosol, but how do they end up where they need to be? With the exception of the few proteins expressed within the chloroplast, the process of shipping nucleus-encoded proteins into the chloroplast is dependent on N-terminal…
