Abstract

We have previously characterised a novel peptide: N-glycanase (PNGase) activity which is developmentally regulated during fruit ripening in tomato. Work in other laboratories has also indicated that free N-glycans, the products of PNGase activity, may be important signalling molecules in plants. We have now identified genes encoding PNGase enzymes in both Arabidopsis and tomato, opening the way for a detailed investigation of the role of PNGases and their products in plant biology. We aim to use over-expression and co-suppression approaches to study the role of PNGase enzyme activity and free N-glycan levels during fruit development in tomato, and to employ functional genomics to investigate broader roles for PNGase activity in Arabidopsis. Finally, we will assess the biochemical properties of recombinant PNGase enzymes.
