Abstract
GUSA from Escherichia coli, encoded by the uidA gene, has been successfully used as a plant reporter system for more than a decade with no reported deleterious effects. However, when expressed in coordination with a UDP-glucuronosyltransferase isolated from the root cap meristem of Pisum sativum (PsUGT1) at the onset of mitosis, GUSA expression was lethal in pea, alfalfa, and Arabidopsis thaliana. These unexpected results indicate that, under some circumstances, using GUSA in plants is incompatible with life and suggest that the cell-specific lethal phenotype might be useful in selecting for genes specifically involved in regulating the G2-M phase of the cell cycle.
