Toward more cost-effective production of biofuels from plant lignocellulosic biomass
In 1925, Henry Ford observed that fuel is present in all vegetative matter that can be fermented and predicted that Americans would some day grow their own fuel. Last year, global biofuel production reached ...

How an 'evolutionary playground' brings plant genes together
Plants produce a vast array of natural products, many of which we find useful for making things such as drugs. There are likely to be many other plant natural products that remain undiscovered or under-exploited, and research ...
