Besides favorable changes in fatty acids profile, these results
showed for the first time the regulatory connection between separate
metabolic pathways (i.e. phenylpropanoid and fatty acid). The
variations in polyunsaturated fatty acid (PUFA) content affect oil
stability. The thiobarbituric acid reactive substances (TBARS) measurements
show a decrease in the level of oxidation products by
10.21, 50.93 and 86.53% for W86, GT and W92 oil, respectively, in
comparison to control plants (data not published yet). Since the
levels of omega-3 fatty acid in GT and W92 types were almost the
same, while oxidative status substantially changed, the intriguing
question arises: what are the other compounds involved in fatty
acid protection against oxidation?
