Cross-talk between CESAs specific to primary and secondary cell wall production in Arabidopsis thaliana.
Cellulose is synthesized by a specialized family of proteins called CESAs. In Arabidopsis thaliana this family is divided into two groups: those specific to primary cell wall production and those specific to secondary cell wall production. These two groups have been studied extensively in terms of their discrete wall-types with which they are associated, however, very few studies have been undertaken to examine the cross-talk between them. Using a revolutionary system in which a master transcription factor, VND7, has been harnessed to provide on-demand secondary cell wall production in all cells of the plant, I aim to visualize the turn-over from primary cell wall production to secondary cell wall production. To do this, I am employing the use of different fluorescent protein tags on primary wall specific and secondary wall specific CESAs which I image simultaneously during VND7-induced ectopic protoxylem cell differentiation.
