Study finds natural selection favors cheaters

A team of biologists at UCR has now found strong evidence of this cheating. Focusing on the interaction between nitrogen-fixing bacteria, or rhizobia, and their legume hosts spanning about 530 miles of California habitat, the researchers found that natural selection in their study populations favors cheating rhizobia. “Our data show that natural selection favors cheating rhizobia, and support predictions that rhizobia can often subvert plant defenses and evolve to exploit hosts,” said Joel Sachs, a professor of biology in the Department of Evolution, Ecology & Organismal Biology, who led the research team.

mollie veliferaSize matters  to livebearer fish, big fins are a big deal

In a new paper, biologists from the UC Riverside studied the evolution of 40 molly and Limia species, and concluded dorsal fin displays arose first for males to compete with other males, only later being used in courtship displays to females. These changes in fin function went hand in hand with enlargement of the male dorsal fin. The fins reached extreme sizes in a few species and appear to be associated with rapid evolution, especially in mollies.

plant    UCR scientists identify how plants sense temperature

Meng Chen, associate professor of cell biology at the University of California, Riverside, is leading a team to explore the role of phytochrome B, a molecular signaling pathway that may play a pivotal role in how plants respond to temperature. With a temperature sensor in hand, researchers can engineer crops that produce yields in warmer climates. Read the article "Daytime temperature is sensed by phytochrome B in Arabidopsis through a transcriptional activator HEMERA" published in Nature on January 11th, 2019.

Varroa Mite
Bee mite arrival in Hawaii causes pathogen changes in honeybee predators

A team led by entomologists at the University of California, Riverside, performed a study on the Big Island and found viruses associated with the mite have spilled over into the western yellowjacket, a honeybee predator and honey raider. The result is a hidden, yet remarkable, change in the genetic diversity of viruses associated with the larger pathogen community of the mite and wasp, with repercussions yet to be understood.
