Role of nitrogen-status and phenylpropanoid metabolism on heat and drought resilience in grapevine

The phenylpropanoid pathway is crucial in plant secondary metabolism, driving the synthesis of a wide variety of defense-related compounds which contribute in maintaining redox homeostasis and enhancing resilience against abiotic stresses. The pathway is initiated by the deamination of phenylalanine via phenylalanine ammonia-lyase. The ammonia generated is then incorporated into amino acid metabolism by glutamine synthetase, highlighting the interconnectedness of the phenylpropanoid pathway and nitrogen metabolism. This project aims to explore the intricate signaling mechanisms that govern the regulation of the phenylpropanoid pathway in response to the plant's nitrogen status.
