Abstract

We propose (a) to test the hypothesis that some plants, particularly cucurbits, possess cells associated with the phloem that are specialised to metabolise amino acids; (b) to test the hypothesis that certain phloem elements in cucurbits are specialised to transport amino acids, and (c) to investigate phloem-associated metabolism that is linked to the transport of amino acids. We will use immunolocalisation to determine the location of marker enzymes of primary metabolic pathways, of amino acid, amide and ureide biosynthesis and specific amino acid transporters in relation to the phloem in tissues of cucumber and other plants at different stages of development. We will localise transported amino acids within the phloem of cucumber.
