Brefeldin A, an inhibitor of protein secretion, caused typical alterations to the endomembrane system with limited effects on viability when given to unorganized carrot cells growing in suspension. When given to the same cells during particular stages of embryogenesis, it caused similar endomembrane lesions and an almost complete arrest of the embryogenic process. Addition of conditioned medium containing extracellular secreted proteins to the embryos during treatment with Brefeldin A allowed acquisition of polarity and the continuation of a quasi-normal embryogenic process.

Abstract
Brefeldin A, an inhibitor of protein secretion, caused typical alterations to the endomembrane system with limited effects on viability when given to unorganized carrot cells growing in suspension. When given to the same cells during particular stages of embryogenesis, it caused similar endomembrane lesions and an almost complete arrest of the embryogenic process. Addition of conditioned medium containing extracellular secreted proteins to the embryos during treatment with Brefeldin A allowed acquisition of polarity and the continuation of a quasi-normal embryogenic process.File in questo prodotto:
