Abstract

Plant cells produce and accumulate insoluble triglycerides, proteins, and rubber that are assembled into inert, ER-derived organelles broadly termed as ER bodies. ER bodies appear to originate from tubular ER domains that are maintained by cytoskeletal interactions and integral ER proteins. ER bodies sequestering insoluble substances usually are transferred to the vacuole but sometimes remain as cytoplasmic organelles. Some otherwise soluble ER-synthesized proteins are converted to insoluble aggregates to produce ER bodies for transfer to the vacuole. This process constitutes an alternate secretory system to assemble and traffic transport-incompetent insoluble materials.
