Scientists Crack Bee-Killer Genome
June 5, 2009| |
Researchers at the USDA Agricultural Research Service (ARS) have successfully deciphered the genome of an important bee pathogen. Nosema ceranae, a unicellular spore-producing parasite, is one of many pathogens suspected of contributing to the Colony Collapse Disorder (CCD). CCD was first reported in the US in October 2006, with some beekeepers reporting losses of up to 90 percent. At stake are honey bees, which according to USDA, play an important part in a $15 billion industry of crop farming in the country.
The Nosema genome is 7.86 Mb long, according to the paper published by PLoS Pathogens. The characterization of the N. ceranae genome presented could advance the understanding and eventual mitigation of Nosema parasitism. The researchers have identified some 89 genes that may play important roles in Nosema-honey bee interactions. These genes are said to encode secretory proteins that may interact with host tissue.
