A research team led by the University of Washington and Pacific Northwest National Laboratory has shown that microbes taken from trees growing beside pristine mountain-fed streams in Western Washington could make phosphorus trapped in soils more accessible to agricultural crops. The findings were published in October in the journal Frontiers in Plant Science.

Broccoli in space: How probiotics could help grow veggies in microgravity

broccoli going to space.

Astronauts at the International Space Station are spending more time away from Earth, but they still need their daily serving of vegetables. In the quest to find a viable way for crew to grow their own veggies while orbiting — and possibly one day on the moon or Mars — student researchers are sending broccoli…

Microbes help plants survive in severe drought

Poplars given microbes survived better in drought conditions

Plants can better tolerate drought and other stressors with the help of natural microbes, University of Washington research has found. Specifically, plants that are given a dose of microbes stay green longer and are able to withstand drought conditions by growing more leaves and roots and using less water.

Bacteria in branches naturally fertilize trees

Young poplar and willow trees along the Snoqualmie River.

A University of Washington team has demonstrated that poplar trees growing in rocky, inhospitable terrain harbor bacteria within them that could provide valuable nutrients to help the plant grow.
