Gamma-Glutamylcysteine Synthetase

Oxygen is partially reduced into reactive oxygen species (ROS) during aerobic metabolism. In plant cells ROS are produced in the various cell compartments. This work is focused on the g-ECS gene that encodes for g-ECS. The major findings of this work are the tomato g-ECS protein encodes for a 523-amino acid and is encoded by a single gene. The identification of IL 8-3 as harboring the Lpa g-ECS ortholog, assigned this gene to chromosome 8. g-ECS was found to be expressed in various organs of the two tomato species. Based on the finding that the transcription level of -ECS was upregulated under salinity and cadmium stresses, only and similarly in Lpa and IL 8-3, it was concluded that the lack of this up-regulation in Lem under stress results from a mutation in its cis-regulatory element(s) and not in gene(s) encoding trans-regulatory factor(s).
