After wildfires, do microbes exhale potent greenhouse gas?

Laughing gas is no laughing matter — nitrous oxide is a greenhouse gas with 300 times the warming potential of carbon dioxide. Scientists are racing to learn whether microorganisms send more of it into the atmosphere after wildfires.

Drought increases microbe-laden dust landing in Sierras

Dust from all over the world is landing in the Sierra Nevada mountains carrying microbes that are toxic to both plants and humans. Research from UC Riverside shows higher concentrations of the dust are landing at lower elevations, where people are more likely to be hiking.

Why doesn’t fire kill some bacteria and fungi?

UC Riverside scientists will spend the next three years studying the traits that allow soil microbes to respond to fire, as well as the role those microbes play in storing or emitting powerful greenhouse gases like carbon dioxide or nitrous oxide.

Human gut bacteria have sex to share vitamin B12

Your gut bacteria need vitamin B12 just as much as you do. Though DNA is usually passed from parent to child, new research shows gut bacteria transfer genes through “sex” in order to take their vitamins.

Root bacteria could help defeat fatal citrus disease

A UC Riverside-led team is looking at tiny underground microorganisms for a way to prevent a huge problem — Huanglongbing, a disease with no cure that has decimated citrus orchards worldwide. The National Institute of Food and Agriculture has awarded the team $10 million to investigate the role of soil...

Proteins enable crop-infecting fungi to ‘smell’ food

New UC Riverside research shows the same proteins that enable human senses such as smell also allow certain fungi to sense something they can eat. The study offers new avenues for protecting people from starvation due to pathogenic fungus-induced food shortages. Understanding how fungi sense and digest plants can also...

UC Riverside discovers first effective treatment for citrus-destroying disease

UC Riverside scientists have found the first substance capable of controlling Citrus Greening Disease, which has devastated citrus farms in Florida and also threatens California. The new treatment effectively kills the bacterium causing the disease with a naturally occurring molecule found in wild citrus relatives. This molecule, an antimicrobial peptide...

Microbiome confers resistance to cholera

Many parts of the world are in the midst of a deadly pandemic of cholera, an extreme form of watery diarrhea. UC Riverside scientists have discovered specific gut bacteria make some people resistant to it — a finding that could save lives.

UCR Herbarium founder donates $900K to preserve its future

UC Riverside’s herbarium, established over 60 years ago, is an irreplaceable library of plant specimens. Now, a $900,000 bequest from its founder Frank Vasek and his wife Maxine will ensure the resource remains available to many generations of future plant scientists, and that it receives needed repairs and reorganization. Vasek...
