Airborne Gut Action Helps Wild Chili Pepper Seeds
2013-06-24 07:25:08

University of Washington Scientists have long known that seeds gobbled by birds and dispersed across the landscape tend to fare better than those that fall near parent plants where seed-hungry predators and pathogens are more concentrated. Now it turns out it might not just be the trip through the air that's important, but also the inches-long trip through the bird. Seeds from a wild chili pepper plant found in South America, after being eaten and passed through the digestive tract...

Self-fertilizing Plants Play Part In Their Own Death
2013-06-10 10:28:56

University of Toronto Many plants are self-fertilizing, meaning they act as both mother and father to their own seeds. This strategy — known as selfing — guarantees reproduction but, over time, leads to reduced diversity and the accumulation of harmful mutations. A new study published in the scientific journal Nature Genetics shows that these negative consequences are apparent across a selfing plant's genome, and can arise more rapidly than previously thought. In the study,...

Sperm cell release can be triggered by tightening the grip around the delivery organ, according to a team of nano and microsystems engineers and plant biologists at the University of Montreal and Concordia University. Concordia's nanobiotech team devised a microchip that enabled the University of Montreal biologists to observe what happened when pollen tubes — the sperm delivery tools used by plants — tried to negotiate a microscopic obstacle course. The pollen tubes were exposed...
