摘要： An endogenous oil extracted from Brassica seeds is disclosed that contains, after crushing and extraction, greater than 86% oleic acid and less than 2.5% .alpha.-linolenic acid. The oil also contains less than 7% linoleic acid. The Brassica seeds are produced by plants that contain seed-specific inhibition of microsomal oleate desaturase and microsomal linoleate desaturase gene expression. Such inhibition can be created by cosuppression or antisense technology. Such an oil has a very high oxidative stability in the absence of added antioxidants.

摘要： This invention relates to isolated nucleic acid fragments encoding all or a substantial portion of Vernonia galamenensis fatty acid modifying enzymes. The invention also relates to the construction of chimeric genes encoding all or a portion of Vernonia galamenensis fatty acid modifying enzymes, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of a Vernonia galamenensis fatty acid modifying enzymes in a transformed host cells.
