Recent advances in systems microbiology.

abstract：:The détente between pathogen and host has been of keen interest to researchers in spite of being exceedingly difficult to probe. Recently, new RNA interference (RNAi) technologies, in particular in Drosophila tissue culture cells, have made it possible to interrogate the genetics of host organisms rapidly, with nearly...
