PIG GENOME UPDATE 20 SEPTEMBER 1, 1996
Tours was magnifique! The 25th International Society of Animal Genetics
meeting in Tours, France was attended by over 500 individuals. These
meetings highlighted recent advances in quantitative and molecular genetics.
Several excellent plenary sessions were held and included topics on disease
resistance, QTL discoveries, genetic diversity and uses of animal models.
In addition, there was an abundance of workshops including those on blood
groups in different species, QTL analyses, comparative gene mapping, gene
mapping for many species, immune response, and genetic diversity. The pig
gene mapping workshop was extremely well attended by nearly 90 individuals
including a large group from the U.S. pig gene mappers. Physical and
genetic linkage maps were updated and it appears that the combined genetic
linkage map has over 1500 genes and markers. Highlights of the meeting
included reports of a growing number of important regions of the genome that
have a significant effect on economically important traits. A review of
this work may be published in some form in the coming months. The pig gene
mapping workshop committee for 1998 will include Alan Archibald (Scotland),
Betram Brening (Germany), Denis Milan (France), Gary Rohrer (US), Chris
Moran (Australia), Bhanu Chowdhary (Sweden) and Max Rothschild (US). Over
500 posters were presented. Several posters included new mapping results
and evidence for QTL in pigs and other livestock. These QTL included those
for litter size, ovulation rate, growth and carcass traits. Additional
highlights of the meeting included one afternoon seeing local sights, an
incredible gala dinner and first rate convention facilities. Our French
hosts, INRA, the ISAG Society officers, and especially Dr. Guerin, should
be congratulated on their efforts.
The 88th Annual Meeting of the American Society of Animal Science and
Western Section Meeting was held July 23-26 in Rapid City, South Dakota.
There were about 2050 people who attended this meeting. Several papers were
presented on gene identification, gene mapping and QTL mapping for pigs,
cattle and sheep. These included a paper on four chemokine genes which are
related to immune systems, TGFB-2, TGFB-3, IL-8 and MCP, and which were
mapped to pig chromosomes 10, 7, 8 and 12 respectively. An integrated
physical and genetic linkage map of swine chromosome 7 including 10 physical
assignments was constructed using cosmids. Two QTL mapping papers were
presented including results that PIT-1 was very close to a QTL for birth
weight on pig chromosome 13 and that possible QTLs for ovulation rate were
located on chromosomes 4, 8, 13, 14 and 15 using genomic scanning
techniques. Several papers reported on methods of linkage phase evaluation
and QTL detection. Abstracts are published and available for ASAS members on
the web at http://www.asas.org/jas.html. (kindly provided by Dr. Lizhen Wang).
Collaboration and cooperation were the themes of a recent small meeting
involving university and USDA administrators, advisors, genome coordinators,
and university and USDA-ARS scientists. The meeting was chaired by Dr. Neal
Jorgensen, University of Wisconsin, and Dr. Dan Laster, USDA-ARS. Of
primary concern was the continued improvement of the genome databases, but
other topics included coordinator-sponsored activities and the renewal of
the NRSP-8. If you are supportive of coordinator activities and NRSP-8, or
have suggestions or concerns about improvement, please contact the
individual coordinators or the new administrative advisor for NRSP-8,
Dr. Colin Scanes, Iowa State University.
The largest single porcine genetic linkage map was recently published
(Genome Research 6:371-391) by Dr. Gary Rohrer and colleagues from the
USDA-ARS MARC facility. The map includes 1116 genes and markers and this
ties together many markers from previous maps. This is an extremely useful
map and can be seen on the USDA WWW homepage and through the NAGRP Pig
Genome homepage.
Revisions of the North Central Regional Project NC-210 "Mapping the Pig
Genome" are underway. A meeting was held in Tours during ISAG to get the
organization started . Objectives were agreed upon and writing teams were
formed. It was decided that we would meet on October 17-18 in Lincoln,
Nebraska. A block of rooms has been reserved at the Ramada Plaza Hotel, 141
North 9th Street, Lincoln, NE 68508-9011, telephone: 402-475-4011 and fax:
402-475-9011. Rooms are held under the group name "NC-210" and can be
reserved by calling 1-800-432-0002 until September 24. Rates are $56 for
single and $61 for double, plus 9.5% tax. The Ramada Plaza Hotel operates a
free shuttle van from the Lincoln airport. Upon arrival, use the courtesy
phone to contact the hotel. Daniel Pomp will be providing transportation
between the hotel and the Animal Science Department on the East Campus of
the University of Nebraska, where the meeting will take place. Please notify
Daniel Pomp (dpomp@unlinfo2.unl.edu) by September 25 if you plan to attend
the meeting so that local arrangements can be finalized. We hope to see you
there.
More fluorescent primers for genotyping will soon be available! An
additional 33 pairs of primers are now being synthesized. This will make a
total 96 fluorescent primer pairs that are available from the U.S. Pig
Genome Coordinator. Each primer pair is composed of one fluorescently
labeled and one unlabeled primer. Information for these 33 pairs of primers
was kindly supplied by Dr. Martien Groenen (Wageningen). If you wish to
receive a new set or the entire set, please contact the U.S. Pig
Coordinator directly.
Got an idea to share resources? We are always looking for ideas from pig
gene mappers. In the past, people have suggested sharing primers, DNA and
information about databases and funds for travel. We already have
accomplished many of these suggestions. Other ideas of services that can be
provided as part of the coordination effort are under consideration. Your
thoughts would be appreciated.
Collaboration with the search for the RN gene is being sought. Several INRA
groups have been working on the RN gene for years. As you may know, the RN
locus is associated with a meat quality trait in pigs. The main effect of
the unfavorable (and dominant) RN- allele is a decrease of the technological
yield during the process of ham cooking. Pascale Le Roy and co-workers
(INRA Jouy) demonstrated that a major gene, RN, is responsible for the
trait. It has been shown that RN phenotypes can be identified by analysis
of muscular Glycolytic Potential. Denis Milan and co-workers (INRA
Toulouse) mapped RN to pig chromosome 15 last year. This result has been
confirmed by Leif Andersson's and Christian Looft's groups. The RN locus is
presently mapped in a 7 cM interval. There is a project to develop new
markers in the RN region and to also try to identify RN by a positional
candidate gene approach. DNA samples of animals of various origins with
known RN phenotypes are being collected and collaboration with the French
groups is being sought. Anyone interested in collaborating, please contact
Denis Milan & Pascale Le Roy, INRA, FRANCE at milan@toulouse.inra.fr or
leroy@dga.jouy.inra.fr. Thank you.
Plant and Animal Genome V ( PAGV) will be held January 12-16, 1997. The

A conference entitled "Allerton II: Genetic Analysis of Economically
Important Traits in Livestock" will be held November 6-9, 1996 at
Monticello, Illinois. The conference will provide a forum for discussion and
analysis of the most up-to-date information on strategies for detection,
isolation, and utilization of ETL in domestic animal species. For full
conference information including program and on-line registration tune your

GDB Links to Mammalian Homology, Enzyme Function Data. Genome Database
(GDB) has reestablished links from over 1500 GDB human gene entries to
mammalian homology data within the Mouse Genome Database (MGD) and to over
400 enzyme entries within the ENZYME database. Both types of links are
accessible from gene entries in GDB. Although its primary focus is the
mouse, MGD=92s homology data also includes gene symbols, chromosomal
locations, and citations regarding numerous mammalian species. Mammalian
homology data can be accessed from GDB by querying for a specific human gene
(e.g., SOD1) and following the homology link to the relevant MGD entry.
ENZYME database entries include the reaction catalyzed, cofactors, links to
the PROSITE database (protein sites and patterns), and detailed SWISS-PROT
entries. ENZYME database links are from protein products rather than from
gene entries themselves. For example, the enzyme link for the human SOD1
gene can be found by querying for this gene, choosing "Protein SUPEROXIDE
DISMUTASE" from the Gene SOD1 entry, and then selecting the "EC:1.15.1.1."
link. (This note is reprinted from Human Genome News, sponsored by the U.S.
