Endosymbiosis: Past and present

Article Abstract:

Wolbachia sp. genome analysis that could provide new potential drug targets and shed light on endosymbiont evolution is discussed. The bacteria may be essential for their nematode hosts in contrast to the case of many arthropods in which Wolbachia are considered parasitic and can be removed by the use of antibiotics.

Fine-scale genetic structure of grape phylloxera from the roots and leaves of Vitis

Article Abstract:

Genetic variation in phylloxera from a vineyard block is examined. The findings suggest limited dispersal of root and leaf feeding phylloxera and factors other than vine host to be important that contribute to clonal structure within populations.
