The Collaborative Cross (CC) was designed to facilitate rapid gene mapping and consists of hundreds of recombinant inbred lines descended from eight diverse inbred founder strains. A decade in production, it can now be applied to mapping projects. Here, we provide a proof of principle for rapid identification of major-effect genes using the CC. To do so, we chose coat color traits since the loc...

The nuclease is a surface enzyme unique to trypanosomatid parasites. These organisms lack the pathway for de novo purine biosynthesis and thus are entirely dependent upon their hosts to supply this nutrient for their survival, growth, and multiplication. There is a cluster on chromosome 30 which carries 2 copy of nuclease genes and 5 identical nuclease like proteins in L. major which are in cis...

In the evolution of the adaptive immune system unique to vertebrates, teleost fish occupy the critical position. This is the most primitive class of lower vertebrates in which the capacity for acute allograft rejections can be demonstrated, thus suggesting the presence of major histocompatibility complex (MHC) antigens and, therefore, T cells. Here, we report the identification of two putative ...
