Formation of wheat protein bodies: Involvement of the Golgi apparatus in gliadin transport.

abstract：:The fluorescent dye Lucifer Yellow CH (LYCH) was introduced directly into the symplast of potato (Solanum tuberosum L.) tuber storage parenchyma by microinjection and also into the apoplast through cuts made in the stolon cortex. Microinjected LYCH moved away rapidly from a single storage cell and spread radially via ...
