Abstract

We investigated the relationship between the cellular redox state of GSH or GSSG and tracheary element (TE) differentiation using a Zinnia experimental system, in which isolated mesophyll cells transdifferentiate to TEs. TE differentiation was suppressed by the application of L-buthionine sulfoximine (BSO), a potent inhibitor of GSH biosynthesis, at the early stage of cell culture. Application of GSSG at the early culture stage promoted the differentiation, but that of GSH or GSSG at an advanced period of culture suppressed the differentiation. Application of GSH and GSSG nullified the TE differentiation-suppressing effect of BSO. The results suggest that changes in the redox states of GSH and GSSG have a role in TE differentiation.
