Newly identified gene reduces pollen number of plants

Producing fewer sperm cells can be advantageous in self-fertilizing plants. An international study led by the University of Zurich identified a gene in the model plant Arabidopsis that reduces the amount of pollen. In addition ...

To predict an epidemic, evolution can't be ignored

When scientists try to predict the spread of something across populations—anything from a coronavirus to misinformation—they use complex mathematical models to do so. Typically, they'll study the first few steps in which ...

New model shows how crop rotation helps combat plant pests

A new computational model shows how different patterns of crop rotation—planting different crops at different times in the same field—can impact long-term yield when the crops are threatened by plant pathogens. Maria ...
