Scientists transform tobacco info factory for high-value proteins

For thousands of years, plants have produced food for humans, but with genetic tweaks, they can also manufacture proteins like Ebola vaccines, antibodies to combat a range of conditions, and now, cellulase that is used in food processing and to…

Climate change could affect symbiotic relationships between microorganisms and trees

Some fungi and bacteria live in close association, or symbiosis, with tree roots in forest soil to obtain mutual benefits. The microorganisms help trees access water and nutrients from the atmosphere or soil, sequester carbon, and withstand the effects of…

Aggressive, non-native wetland plants squelch species richness more than dominant natives do

Dominant, non-native plants reduce wetland biodiversity and abundance more than native plants do, researchers report in the journal Ecology Letters. Even native plants that dominate wetland landscapes play better with others, the team found. The researchers analyzed 20 years of…
