Abstract excerpt
Trehalose and associated metabolites are part of the sugar signalling system in plants and have profound effects on development. Disruption of the TREHALOSE 6-PHOSPHATE SYNTHASE (TPS1) gene in Arabidopsis results in delayed embryo growth, altered cell wall morphology and carbon metabolism and abortion at the torpedo stage. Here we investigate the role of the TPS1 gene in post-embryonic development using two...
