Abstract: A marigold plant, a regenerable portion thereof and seed are disclosed whose flower petals, leaves or flower petals and leaves contain one or more of an enhanced neoxanthin plus violaxanthin ratio, an enhanced ?-carotene ratio, an enhanced lycopene ratio, an enhanced ?-cryptoxanthin ratio, an enhanced phytoene ratio or an enhanced phytofluene ratio relative to that ratio in a non-mutant marigold. A marigold plant, a regenerable portion thereof and seed are also disclosed whose flower petals contain zeaxanthin esters and are substantially free of esters of both neoxanthin and violaxanthin, and wherein zeaxanthin constitutes at least about one-half of the extractable carotenoids when xanthophylls are assayed as alcohols. Also disclosed are methods of preparing such plants, oleoresins and comestible materials that have such carotenoid ratios.

Abstract: Since its introduction into North America over 170 years ago, the poinsettia has become a major ornamental potted plant, and is an important component of the U.S. floral industry. Susceptibility to insect pests and diseases caused by pathogens remains a problem for poinsettia production, even under greenhouse conditions. While chemical treatment can control certain insect pests and disease pathogens, such treatment can also have an adverse effect upon poinsettias. The methods described herein provide a means to genetically engineer transgenic poinsettia that express macromolecules capable of protecting the plant against the insects and pathogens. The production of transgenic plants can also be used to enhance the commercial value of poinsettia by controlling characteristics such as flower color.
