h-ERES-y in ER-Golgi transport

Abstract

A debate continues over whether the Golgi is a stable organelle or a transient manifestation of continuous membrane flow from specialized ER exit domains (ERES). A new study from daSilva and colleagues shows that in plant cells, individual Golgi always form adjacent to an existing ERES, and that an ERES and its associated Golgi stack move as a single secretory unit. Their results support a model in which Golgi biogenesis correlates with ERES function.
