Mutations in the Drosophila gene polo cause abnormal mitotic and meiotic divisions. This gene encodes a 577-amino-acid protein that has an N-terminal putative kinase domain and a 300-residue C-terminal domain. In budding yeast, a homologous kinase is encoded by CDC5 (ref. 3), a gene required for nuclear division late in the mitotic cycle and during meiosis.(More)
BACKGROUND Global commerce and human transportation are responsible for the range expansion of various insect pests such as the plant sucking aphids. High resolution DNA markers provide the opportunity to examine the genetic structure of aphid populations, identify aphid genotypes and infer their evolutionary history and routes of expansion which is of(More)
BACKGROUND The green peach aphid, Myzus persicae (Sulzer), is a world-wide insect pest capable of infesting more than 40 plant families, including many crop species. However, despite the significant damage inflicted by M. persicae in agricultural systems through direct feeding damage and by its ability to transmit plant viruses, limited genomic information(More)
Potato is produced on all continents except Antarctica and is the world’s third most important food crop. Potato production has increased dramatically in developing countries in the past two decades, and has now overtaken that in the developed world, underlining the growing importance of potato as a staple food crop to meet the demands of increasing human(More)
Small mammal species are abundant and common throughout Europe and often utilise areas that are subject to agricultural land use. Arable farmland is an example of a frequently disturbed habitat, and this study questioned how such disturbance affected the two most common species in the region; one a habitat generalist and one a habitat specialist. We(More)
