Abstract:
Oilseed rape (Brassica napus) is the most important oilseed crop in the UK. The seed-oil is made up of many different fatty acids and the optimisation of the fat acid composition of rapeseed oil is a key plant breeding objective. Fatty acid profiles are key determinants of the fitness of rapeseed oil for its potential end-uses. This thesis reports the identification and mapping of candidate gene homologues and QTL involved in the fatty acid desaturation pathway responsible for the unsaturated fatty acid content of rapeseed oil. The candidate genes FAB2, FAD2 and FAD3 are known in Arabidopsis thaliana to encode the desaturase enzymes responsible for most of the conversions in seed-oil of: stearic acid to oleic acid (FAB2), oleic acid to linoleic acid (FAD2), and linoleic acid to linolenic acid (FADS). The gene FAE1, which controls fatty acid elongation to produce erucic acid, strongly influences the fatty acid desaturation pathway and was also investigated.
