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, …

Barley genome sequenced

A group of 77 scientists worldwide have sequenced the complete genome of barley, a key ingredient in beer and single malt Scotch.

Tea tree genome contains clues about how one leaf produces so many flavors

The most popular varieties of tea—including black tea, green tea, Oolong tea, white tea, and chai—all come from the leaves of the evergreen shrub Camellia sinensis, otherwise known as the tea tree. Despite tea’s immense cultural and economic significance, relatively little is known about the shrub behind the tea leaves. …

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 …
