Abstract

We have recently discovered that Trehalose-6-phosphate synthase 1 (TPS1), which catalyses the first step in trehalose synthesis, is essential for embryo maturation in Arabidopsis (Eastmond et al., Plant Journal, in Press). The tps1 mutant is a recessive embryo lethal. Our data suggest that trehalose metabolism plays a key role in regulating storage reserve accumulation by allowing the embryo to respond to the dramatic increase in sucrose level which occurs at the torpedo stage of embryo development. This project seeks to establish whether T-6-P is the key regulator; what the cellular targets for regulation are and the significance of trehalose metabolism in the control of genes involved in storage reserve accumulation.
