Researchers generate tomatoes with enhanced antioxidant properties by genetic engineering

The School of Biological Sciences, Faculty of Science, the University of Hong Kong (HKU), in collaboration with the Institut de Biologie Moléculaire des Plantes (CNRS, Strasbourg, France), has identified a new strategy to simultaneously enhance health-promoting vitamin E by ~6-fold and double both provitamin A and lycopene contents in tomatoes, …

Genetic engineering tool generates antioxidant-rich purple rice

Researchers in China have developed a genetic engineering approach capable of delivering many genes at once and used it to make rice endosperm (seed tissue that provides nutrients to the developing plant embryo) produce high levels of antioxidant-boosting pigments called anthocyanins. The resulting purple endosperm rice holds potential for decreasing …

Reversing pest resistance to GM cotton

Insect pests that are rapidly adapting to genetically engineered crops threaten agriculture worldwide. A new study published in the Proceedings of the National Academy of Sciences reveals the success of a surprising strategy for countering this problem: Hybridizing genetically engineered cotton with conventional cotton reduced resistance in the pink bollworm, …

Rice expressing mutant forms of GA 2-oxidase shows increased yield and tolerance to stress conditions

Optimizing plant architecture to increase yield, stress tolerance, and water use efficiency (WUE) is a major challenge for modern agricultural biotechnology. Gibberellins are growth hormones known to be directly related to plant height and tillering, which in turn are directly related to grain yield in cereals. GA 2-oxidase is a …

New sugarcane as a feedstock for biodiesel and ethanol

Biodiesel production in the U.S. from vegetable oils has increased substantially during the past decade. However, its further increase is limited by the low amounts of oil produced per hectare from temperate oilseed crops. Recently novel transgenic sugarcane has been developed to accumulate both sugars and lipids in stems, making …
