Microscopic visualization of the ARP2/3 complex showed that it colocalizes with peroxisomes in Arabidopsis thaliana and tobacco cells in vivo. Colocalization with an autophagy marker and analysis of peroxisomes in autophagy-mutant or ARP2/3-mutant lines demonstrated that ARP2/3 facilitates peroxisome degradation by the autophagic pathway, that is, pexophagy.
