| secondary intracellular symbiotic bacteria in aphids of the genus yamatocallis (homoptera: aphididae: drepanosiphinae). | a novel secondary intracellular symbiotic bacterium from aphids of the genus yamatocallis (subfamily drepanosiphinae) was characterized by using molecular phylogenetic analysis, in situ hybridization, and diagnostic pcr detection. in the aphid tissues, this bacterium (tentatively designated ysms [yamatocallis secondary mycetocyte symbiont]) was found specifically in large cells surrounded by primary mycetocytes harboring buchnera cells. of nine drepanosiphine aphids examined, ysms was detected i ... | 2001 | 11679361 |
