Brief summary of minutes of annual meeting

The 2000 annual meeting for NC-210 was held in conjunction with the Plant and Animal Genome IX conference in San Diego, CA on January 14, 2001. The meeting was held simultaneously with the annual meeting of the NRSP-8 Swine Genome Committee. Four invited speaker presentations were given, along with individual station reports and business meetings for NRSP-8 and NC-210. At the NC-210 business meeting, the merging of the current NC-210 and NC-220 committees to form a single swine genetics research committee was discussed. This committee is planning to write a new multistate project proposal for submission in 2001. Also at the NC-210 business meeting, the current secretary, Jon Beever, assumed the role of chair for 2001 and Max Rothschild was elected as the new secretary. The committee voted to hold the 2001 annual meeting in conjunction with PAG X in San Diego, CA in January 2002. Minutes of the meeting are posted on the U.S. Pig Genome Coordination home page at http://www.genome.iastate.edu/pig.

Accomplishments and Impacts

Objective 1: Develop and apply technology for positional cloning of ETL in the pig.

Several stations (IL, IA, MI, MN, NE) are continuing to map Type I comparative loci using the INRA somatic cell hybrid panel (SCHP) and the INRA-Minnesota porcine radiation hybrid (IMpRH) panel. The IA and MI stations are also identifying single-nucleotide polymorphisms (SNPs) at Type I loci for genetic linkage mapping. Numerous genes, selected based on their comparative location on the human map or for their physiological function, have been mapped in the past year. The IL and MN stations are emphasizing mapping of markers surrounding syntenic chromosomal breakpoints between the human and pig genomes. Expressed sequence tag (EST) projects are underway at several stations (IL, IA, MI, MN, NE, NV). These projects are making thousands of new gene sequences available for comparative mapping. The IL and NV stations have initiated projects to refine the fine scale pig physical map. The NV station is sequencing SLA II and the IL station is using BAC fingerprinting to construct a genome wide physical map. Competitive RT-PCR assays for critical cytokines (IFNg, IL-2, IL-3, IL-4, IL-5, IL-10, IL-12, IL-13. IL-15, IL-18) have been developed at USDA-BARC and are being used to determine gene expression changes in response to infectious diseases. The KS, MI and MN stations contributed new anonymous markers to the pig RH and genetic linkage maps. The KS station added a total of 15 microsatellite markers to the genetic maps of SSC8 and SSC13. The MI station added 18 markers identified using representational difference analysis (RDA) to the RH map and also placed nine of these on the genetic map. The MN station is involved in a large project to identify 1000 new microsatellite markers. To date they have over 300 candidate loci and sequence analysis and RH mapping of these markers is underway. Several stations (IL, IA, MI, MN, NE) are developing new resource populations and/or have conducted quantitative trait loci (QTL) experiments in the past year. The MN station is fine mapping the region of a QTL for number of copora lut ia/ovulation rate on SSC8 and 10 new microsatellite markers have been mapped to this region. The NE station is using mouse models for the fine mapping of heat-loss and obesity QTL. A Berkshire x Duroc F2 population is under development in IL and a Duroc x Pietrain F2 population is under development in MI. A Berkshire x Yorkshire F2 population at the IA station has been completed and 40 traits were measured on 525 animals. A primary genome scan using 125 microsatellite markers revealed over 100 putative QTL significant at the chromosome wide level and 19 of these were significant at the genome wide level.

Objective 2: Identify and analyze the function and expression of genes that regulate traits of economic importance in the pig.

Tissue specific EST libraries have been constructed at several stations (IL, IA, MI, MN, NE, NV). Tissues represented by these libraries include skeletal muscle, placenta, anterior pituitary, ovary, conceptus, fetus, hypothalmas, alveolar macrophages, peripheral blood cells, spleen, thymus, lymph node and bone marrow. Sequence information for these ESTs is being deposited into public databases and is available to pig geneticists and physiologists. Expression profiling experiments using cDNA microarrays and other high-throughput genomics technologies are currently underway. Several stations (IL, IA, USDA-BARC) investigated the roles of candidate genes for economically important traits. The IA station reported validation research for the role of MC4R and PPARG in meat quality. The IL station screened samples from several swine populations for the presence of the mutation in PRKGA3 that is responsible for the RN effect. The USDA-BARC station determined that pigs resistant to T. gondii infection exhibit increased expression of interferon-gamma and interleukin-10 early after infection. In addition, the USDA-BARC station assessed immune gene expression in critical tissues of pigs from one day of age through six weeks of age and comparisons of pigs for resistance to respiratory and intestinal disease challenges are planned. The KS station is exploring strategies that may be useful for enhancing animal production efficiency. They have demonstrated that bone marrow stromal cells can colonize pig fetal tissues and they also induced mesenchymal stem cells to a phenotype resembling neural stem cells and young neurons.

Impacts:

Work done by the NC-210 multistate research committee has significantly enhanced the pig comparative map. The mapping of additional genes and ESTs facilitates the usefulness of the recently published human genome sequence because maps comparing the location of genes on human and mouse chromosomes with their location on pig chromosomes provide a rich source of candidate genes for QTL. The evaluation of expression patterns for genes and ESTs that is currently underway will aid in the determination of the functional roles of these genes in controlling economically important traits. A significant number of markers were added to the pig genetic linkage map. These markers included both Type I (gene) and Type II (anonymous) markers. These new markers will aid in the positional cloning of genes at QTL because having many markers available in regions harboring QTL considerably speeds the process of determining the exact position of the QTL and leads to its eventual identification. Once the genes at QTL are identified, it will be possible to improve the efficiency and reduce the costs of pork production by improving the speed and accuracy of selection programs. In addition, several resource populations are currently under development for the identification of QTL affecting carcass merit and pork quality. Initial results from one of these populations have revealed numerous QTL regions that can now be targeted for identification of the specific genes controlling the production of desirable pork products. The identification of specific genes having a major effect on growth, carcass merit, reproductive efficiency and health promises to facilitate the production of a significantly improved pork product at reduced costs. American agriculture will thus be more competitive on the world market.

Plans for the coming year:

Work planned by the NC-210 Committee for next year includes further refinement of the pig comparative map. In addition, new anonymous markers will be identified and located on the genetic linkage map. Several stations are planning to sequence and map a significant number of ESTs. In addition, these ESTs will be used in expression profiling experiments for numerous tissues. New resource populations are under development and will be used for QTL identification. Fine mapping of regions containing previously identified QTL will continue.
