General Information

General Information Comment Organism
malfunction expression of TPS1 driven by the ABI3 promoter rescues the severe embryo phenotype but not the vegetative phenotype of tps1. tps1 exhibits a severe phenotype in vegetative tissue, consistent with the role played in embryo development Arabidopsis thaliana
physiological function the TPS1 protein is a key regulator of trehalose metabolism throughout the Arabidopsis life cycle and not just in embryo development, it plays a key role in modulating trehalose 6-phosphate levels in vegetative tissues of Arabidopsis thaliana Arabidopsis thaliana
