Syllabus
Introduction - the importance of transport processes and compound distribution in growth and development of plants, major compounds transported for a long distance Mechanisms of transport processes - diffusion, facilitated diffusion, active transport, bulk flow Characterisation of structures involved in transport processes- membranes, plasmodesmata, phloem, xylem. Long distance transport - xylem, water and mineral nutrients transport, capilarity, transpiration, Long distance transport of assimilates, phloem loading, phloem unloading
Transport of amino acids, phytohormones, signalling compounds and xenobiotics. Short distance transport - chloroplast - cytosol, cytosol-vacuole, cell - cell Sink - source interaction Regulation of inter- and intracellular transport, control of C source allocation during day/night rhythm Saccharide signalling: hexokinase dependent and independent hexose signalling, SnRK signalling of C avalilability shortage, trehalose-6-P signalling
C and N metabolism interactions
