Neatby Bldg, 960 Carling Avenue, Ottawa, Ontario, Canada K1A 0C6, Department of Ecology and Evolutionary Biology, Yale University, New Haven, CT 06520, USA, Department of Entomology, Michigan State University, East Lansing, MI 48824, USA, Northern Research Center, United States Department of Agriculture, Forest Service, Hamden, CT 06514, USA.

The Adelgidae are relatively small, cryptic insects, exhibiting complex life cycles with parthenogenetic reproduction. Due to these characteristics, the taxonomy of the group is problematic. Here, we test the effectiveness of the standard 658-bp barcode fragment from the 5'-end of the mitochondrial cytochrome c oxidase 1 gene (COI) in differentiating among 17 species of Adelgidae, in associating life-cycle stages, and in assessing patterns of geographical variation in selected species.

Length polymorphism and homologies of microsatellites in several Cucurbitaceae species.

Theor Appl Genet

December 1996

Department of Vegetable Crops, Agricultural Research Organization, Northern Research Center, Newe Ya'an, P.O.B. 90000, 31900, Haifa, Israel.

The objectives of this research were to assess (1) the degree of Simple Sequence Repeats (SSR) DNA length polymorphism in melon (Cucumis melo L.) and other species within the Cucurbitaceae family and (2) the possibility of utilizing SSRs flanking primers from single species to other genera or species of Cucurbitaceae. Five melon (CT/GA) n SSRs were isolated from a genomic library.
