Woronin body hitchhiking on early endosomes is dispensable for septal localization in Aspergillus nidulans

Abstract

In the filamentous fungus Aspergillus nidulans, peroxisomes move by hitchhiking on early endosomes. Here, it is shown that the Woronin body, a peroxisome-derived organelle that plugs incomplete septa upon injury to hyphae, also hitchhikes on early endosomes. While hitchhiking is required for Woronin body distribution and motility, it is dispensable for septal localization and plugging.
