Autophagy

Last changed: 18 November 2021

Autophagy (“self-eating”) is a major catabolic process in eukaryotes that involves the sequestration of cytoplasmic contents into double membraned vesicles known as autophagosomes, which are then transported to the lytic vacuole for degradation so that they can be repurposed. Autophagy acts as an intracellular recycling system, playing critical roles in plant development and defence against various forms of environmental stress. Through the implementation of innovative strategies and development of new technologies to study autophagy, we aim to further unravel the underlying mechanisms controlling this vital process with agricultural significance.
