Abstract
In the facultative halophyte Mesembryanthemum crystallinum (common ice plant), irrigation with solutions containing NaCl induces an alternate mode of carbon dioxide fixation, Crassulacean acid metabolism (CAM). The salt stress protocol which we have established facilitates the study of CAM induction and the correlation of changes in metabolism and gene expression. We have studied the time course of mRNA induction for phosphoenolpyruvate carboxylase (PEPCase) (gene: ppc) and several other enzymes of carbon metabolism during stress. While CAM is not fully established for at least 10 days after the start of stress, mRNA amounts for PEPCase and for other CAM enzymes, such as pyruvate orthophosphate dikinase, increase between day 2 and 3 after stress induction. Increase continue for at least 5 days. Concomitant with the increases of CAM transcripts, fluctuations in the mRNA amounts for genes rbcS and cab were observed. Transcript levels for these proteins decreased several-fold during a 3 to 4 day period.This publication has 16 references indexed in Scilit:
