Plant Metabolism and Metabolic Engineering_3

Our research group works in the elucidation of the role of 3-hydroxy-3-methylglutaryl Coenzyme A reductase and protein phosphatase 2A in the plant response to stress. Our results indicate that the interaction between these two factors induces the biogenesis of specific domains of the endoplasmic reticulum. These domains are directly and rapidly delivered to the vacuole to mediate a successful adaptation to the environment. This phenomenon involves a dynamic organization of the endoplasmic reticulum, presumably under control of phytohormones and signal transduction pathways activated in response to stress.
