Consumption of astaxanthin is increasingly associated with a range of health benefits. Attempts to engineer ketocarotenoid biosynthesis in plants have been successful although there are no reports of nutritionally significant levels of astaxanthin in plant storage organs. Thus, in this study, ketocarotenoid biosynthesis was engineered in potato tubers. Both Solanum tuberosum and Solanum phureja transgenic lines were produced that expressed an algal bkt1 gene, encoding a beta-ketolase, and… CONTINUE READING
