Researchers at the University of Hawaiʻi at Mānoa, in collaboration with scientists at the J. Craig Venter Institute, have made a significant breakthrough in developing a novel technology to investigate global gene-expression in a single bacterium. The team, led by Associate Professors Tung T. Hoang and Stuart P. Donachie, recently published a paper describing the technology in Genome Research (21:925-935), a premier international genome journal. UH Mānoa postdoctoral researcher Dr. Yun Kang, who performed this research in a Snyder Hall laboratory, contributed significantly and worked diligently to overcome the numerous technical challenges presented.

*Berkeley Lab scientists decipher immune system for plants beneath our feet*

Those vegetables you had for dinner may have once been protected by an immune system akin to the one that helps you fight disease. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Netherland’s Wageningen University found that plants rely on a complex community of soil microbes to defend themselves against pathogens, much the way mammals harbor a raft of microbes to avoid infections.

The scientists deciphered, for the first time, the group of microbes that enables a patch of soil to suppress a plant-killing pathogen. Previous research on the phenomenon of disease-suppressive soil had identified one or two pathogen-fighting microbes at work. (more…)

Scientists identify key enzyme in microbial immune system

Imagine a war in which you are vastly outnumbered by an enemy that is utterly relentless – attacking you is all it does. The intro to another Terminator movie? No, just another day for microbes such as bacteria and archaea, which face a never-ending onslaught from viruses and invading strands of nucleic acid known as plasmids.
