Scientists learn how to increase corn crop yields

NSF-funded scientists at Cold Spring Harbor Laboratory are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its resources away from maintaining ...

Shifting the balance of growth vs. defense boosts crop yield

Cold Spring Harbor Laboratory (CSHL) scientists are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its resources away from maintaining ...

Plants defend against insects by inducing 'leaky gut syndrome'

Plants may induce "leaky gut syndrome"—permeability of the gut lining—in insects as part of a multipronged strategy for protecting themselves from being eaten, according to researchers at Penn State. By improving our ...
