Exploiting Male-Killing Bacteria to Control Insects

A team of scientists including Assistant Professor of Entomology Omar Akbari have discovered a key mechanism that drives a bacteria that kills male insects, a development that could potentially be exploited to control insect pest species in the future. In a paper published in Current Biology, they describe how the bacterium Spiroplasma initiates male killing by directly targeting the dosage compensation complex of an organism, which equalizes gene expression between the males and females.

Sachs
Bacteria Beneficial to Plants Have Spread Across California

A recent study led by Associate Professor of Biology Joel Sachs and published in the Proceedings of the Royal Society B shows that a strain of beneficial nitrogen-fixing bacteria has spread across California, demonstrating that beneficial bacteria can share some of the same features that are characteristic of pathogens. The bacteria, called Bradyrhizobium, form tumor-like nodules on the roots of plants and are able to “fix” nitrogen by breaking it down and rendering it into forms that plants can easily metabolize.

Scientists Unlock Genetic Secret that Could Help Fight Malaria

Omar Akbari, an assistant professor of entomology, is among group of scientists who have discovered a long-hypothesized male determining gene in the mosquito species that carries malaria, laying the groundwork for the development of strategies that could help control the disease. This is significant because male mosquitoes offer the potential to develop novel vector control strategies to combat diseases, such as malaria and the zika and dengue viruses, because males do not feed on blood or transmit diseases.
