Hamelin, Richard C., Tsui, Clement K.M., Bohlmann, Jörg, DiGuistini, Scott, Dhillon, Braham, Feau, Nicolas, Wang, Ye
Sexual reproduction in fungi is regulated by the mating-type (MAT) locus where recombination is suppressed. We investigated the evolution of MAT loci in eight fungal species belonging to Grosmannia and Ophiostoma (Sordariomycetes, Ascomycota) that include conifer pathogens and beetle symbionts....

Stockey, R.A., Rothwell, G.W., Hernandez-Castillo, G.R., Mapes, G.
A new species of extinct conifer plants, Emporia royalii sp. nov. Hernandez-Castillo, Stockey, Mapes et Rothwell (Emporiaceae: Voltziales), is described from the rich fossil biota of the Late Pennsylvanian, Hamilton Quarry, Kansas. This conifer has lateral plagiotropic branches with simple and...

The expression of mouse embryonic U1 snRNA (mU1b) genes is subject to stage- and tissue-specific control, being restricted to early embryos and adult tissues that contain a high proportion of stem cells capable of further differentiation. To determine the mechanism of this control we have sought...

Background Comparative whole genome analysis of Mammalia can benefit from the addition of more species. The pig is an obvious choice due to its economic and medical importance as well as its evolutionary position in the artiodactyls. Results We have generated ~3.84 million shotgun sequences...

Wong, Barbara, Leal, Isabel, Feau, Nicolas, Dale, Angela, Uzunovic, Adnan, Hamelin, Richard C.
Wood and wood products can harbor microorganisms that can raise phytosanitary concerns in countries importing or exporting these products. To evaluate the efficacy of wood treatment on the survival of microorganisms of phytosanitary concern the method of choice is to grow microbes in petri dishes...

Xing, L., Ji, S., Persons, W. S., Bell, P. R., Ji, Q., Miyashita, T., Currie, P. J., Burns, M. E.
Two skeletons of the large compsognathid Sinocalliopteryx gigas include intact abdominal contents. Both specimens come from the Jianshangou Beds of the lower Yixian Formation (Neocomian), Liaoning, China. The holotype of S. gigas preserves a partial dromaeosaurid leg in the abdominal cavity, here...

The Silkworm Knowledgebase (SilkDB) is a web-based repository for the curation, integration and study of silkworm genetic and genomic data. With the recent accomplishment of a ~6X draft genome sequence of the domestic silkworm (Bombyx mori ), SilkDB provides an integrated representation of the...

Different scales of spatial segregation of two species of feather mites on the wings of a passerine bird
Download2011
Mestre, A., Mesquita-Joanes, F., Proctor, H., Monros, J. S.
The \"condition-specific competition hypothesis\" proposes that coexistence of 2 species is possible when spatial or temporal variations in environmental conditions exist and each species responds differently to those conditions. The distribution of different species of feather mites on their...
