Title: Trehalose-6-phosphate – a sugar signal linking plant development to metabolism

Speaker: John Lunn

Affiliation: Max Planck Institute of Molecular Plant Physiology, Potsdam-Golm, Germany

Host: Isabel Abreu Lab - Proteome Regulation in Plants


Abstract:

Trehalose 6-phosphate (Tre6P) is a signal metabolite that signals and regulates sucrose status in plants, and is analogous to the insulin-glucagon system for regulation of blood glucose levels in animals[1]. Perturbing Tre6P levels in plants leads to diverse developmental and metabolic phenotypes, including embryo arrest, delayed or promiscuous flowering, insensitivity of stomata to abscisic acid, and changes in central carbon and nitrogen metabolism. We are using cell and tissue-specific promoters to dissect the functions of Tre6P in different parts of the plant, with a focus on source leaves, to understand the role of Tre6P in source-sink interactions, and on axillary buds, to elucidate how Tre6P influences shoot branching.
