Abstract:

Organelles are eukaryotic subcellular structures each possessing a specific set of functions. The morphology, abundance, and content of the organelles also undergo constant changes for optimal function and for plant adaptation to environmental variation. The six reviews and one research article published in this special issue on Organelle Biology cover a wide range of topics encompassing recent advances in the studies of the dynamic morphology, abundance, and movement of plant organelles, protein trafficking between organelles, changes in organelle composition and function in response to stress conditions, and machineries involved in the turnover of cellular constituents.
