The steady-state level of potato sucrose synthase mRNA is dependent on wounding, anaerobiosis and sucrose concentration

Gene. 1989 Dec 7;84(1):181-5. doi: 10.1016/0378-1119(89)90153-4.

Abstract

The steady-state level of potato sucrose synthase (SSase) mRNA was investigated in different plant organs and in response to certain stimuli. SSase mRNA is mainly present in developing tubers, but its presence is not restricted to this organ and the transcript is found at detectable levels in all the tissues analysed, except leaves. Wounding results in a decrease in SSase mRNA, but this can be overcome by incubation under anaerobic conditions. In leaves and petioles, an increase in sucrose concentration leads to an increase in SSase mRNA.
