Research and Theories

In biology Robert Mellor is probably best remembered for his "unified vacuole theory" which states that in endosymbioses [] generally, the micro-symbiont and the macro-symbiont share their lytic / vacuolar compartments. This stems from his earlier "symbiosome=lysosome theory" which states that the organelle that microsymbionts inhabit partially takes over the lysosomal [] functions in these cells, analogous to the role of protein bodies in seeds.

In other works Robert Mellor pointed out that in legumes [] , root nodule cytoplasm may be under water stress and the plant may combat this by producing trehalose [] . Indeed this may explain why nodulated plants have a higher drought-tolerance [] than non-nodulated plants.

Mellor was also very interested in how plants distinguish between symbiotic and pathogenic infections and in 1984 set about measuring defence responses in nodules infected with different Rhizobial [] mutants and it gradually appeared that in Rhizobia the nod genes are responsible for producing different nod-factors (lipo-chitin molecules) [] and that amongst their many effects was that they can provoke plant defence responses, so that it was essential that these genes were switched off (by molecules called "nodoffs") after infection, or that symbiosis could not take place. This convincing model won general acclaim and indeed the paper with David Collinge was later reprinted as that year’s number one most important publication.

However Mellor was also interested in applied science and invented and patented a system to power immobilized oxido-reductase enzymes and artificial co-factors using electrical power out of a domestic socket [] !

Present Work

In early 2000 he joined and helped start-up the IT University of Copenhagen [] , after which he became Director of Enterprise at Kingston University [] , London, in Computing, Information Systems and Mathematics. Robert Brooke Mellor [] is author of over 120 scientific publications in reputable journals and ten books, several of which have been translated into other languages. He is an active consultant with over twelve years industrial experience and lectures at postgraduate level on subjects like ‘strategic information systems’, ‘knowledge management’, ‘strategic innovation’ and ‘entrepreneurship’.
