Dissection of phloem transport in cucurbitaceae by metabolomic analysis
This thesis aimed to investigate several fundamental and perplexing questions relating to the phloem loading and transport mechanisms of Cucurbita maxima, by combining metabolomic analysis with cell biological techniques. This putative symplastic loading species has long been used for experiments …

Identification and analysis of new phloem proteins from Brassicaceae and Cucurbitaceae
The major aim of this work was the identification of new phloem sap proteins and a metabolic characterisation of this transport fluid. The experiments were performed on the three plant species C. sativus, C. maxima and B. napus. To characterise the phloem samples from B. napus, a new model plant …
