Molecular analysis of a tomato OGDH antisense line

ABSTRACT: Transgenic tomato (Solanum lycopersicum) plants expressing a fragment of the SlSIOGDH gene encoding subunit E1 of the 2-oxoglutarate dehydrogenase protein complex in the antisense orientation and exhibiting considerable reductions in the activity of this enzyme exhibit a considerably reduced rate of respiration. They were, however, characterised by largely unaltered photosynthetic rates and fruit yield but a restricted leaf, stem and root growth rate. The lines displayed markedly altered metabolic profiles including changes in tricarboxylic acid cycle intermediates and in the majority of the amino acids without alterations in pyridine nucleotide content. Moreover, they displayed a generally accelerated development exhibiting early flowering, accelerated fruit ripening and a markedly earlie
