HAPPY TRAILS. Over the past two months the U.S. Pig Genome Coordinator has
made a couple of trips and visited with several pig and other genome
scientists as well as industry people. Recent successes in both mapping
and major gene detection and the possibility of the NRSP8 being renewed has
created considerable optimism. One trip was to the USDA-ARS MARC in Clay
Center, Nebraska. There were excellent discussions on various research
topics and the hospitality was much appreciated. Some excellent resources
are available from MARC scientists to the gene mapping community (see
below). If you have resources to share please let others know so that we
can all work together.
o o o o o o o o o o o
MORE REFERENCE DNA IS AVAILABLE. It is possible that not everyone knows
the DNA samples from the MARC reference population are available to
scientists who wish to map markers in the porcine genome. DNA from the
USDA original population of 10 parents producing eight litters (94 progeny
total; Rohrer et al. 1994, Genetics 136:231-245) can be received by sending
a request to Dr. Gary Rohrer, U.S. Meat Animal Research Center, PO Box 166,
Clay Center, NE 68933-0166. A litter of eight (produced from a Duroc-White
Composite female) has been removed so that the DNAs from the remaining
litters will fit into a 96-well microtiter plate format. Genotypic data
derived from this population must be entered into the MARC Genome database.
Amount of technical support for linkage analysis will be arranged on an
investigator by investigator basis. In a request for DNA, please indicate
the number of markers expected to be mapped in a given time period, the
amount of DNA used in a typical PCR reaction and whether tubes or a
microtiter plate (set up for multichannel pipettor loading) of DNA is
preferred. International requests may be subject to laws pertaining to
export/import of animal materials. When requests exceed availability of
materials, prioritizing may be required based on mutual scientific interest
and benefit. (information kindly provided by Gary Rohrer)
o o o o o o o o o o o
THE MARC YAC LIBRARIES are also available for use by researchers worldwide,
as stated in the original manuscripts describing the libraries. A number
of laboratories in the U.S. and abroad are currently making use of this
resource. The DNA pools can be received by sending a written request to
Dr. Tim Smith, U.S. Meat Animal Research Center, PO Box 166, Clay Center,
NE 68933-0166. International requests may be subject to U.S. trade laws.
Researchers are reminded that patent claims resulting from use of the YACs
may be affected by the fact that the YACs are U.S. government property.
Initially, Dr. Smith will send requesting parties the super pools only (15
bovine, 23 porcine) for screening and then send appropriate secondary pools
as they are identified. In return for access to the library, screening
data derived from the pools, including primer sequences used, must be
provided for the MARC YAC database. This information will be in strict
confidence until such time as the data owner notifies Dr. Smith of release.
Amount of support for screening, use, and handling of the libraries will
be arranged on an investigator by investigator basis. Potential users of
the library are advised to have patience since sharing of YACs is subject
to time constraints at the USDA end and because there are 350 DNA pools for
each library requiring substantial time for Dr. Smith to label and aliquot.
In addition, production of the DNA pools is a relatively massive endeavor
and if the number of requests becomes large, they will be prioritized
according to mutual scientific interest and benefit. (information kindly
provided by Tim Smith)

MANY THANKS AND BEST WISHES to Dr. Lizhen Wang. Lizhen has served as our
database manager and assistant to the Pig Genome Coordinator for nearly the
past four years. She has helped to manage ANGENMAP, work with your
questions and assist many of you in the pig genome mapping community. Dr.
Wang will be taking on a new challenge as she goes to work for Babcock
Swine in La Crosse, Wisconsin. She will be sorely missed. If you want to
send her a note of thanks, her present e-mail is wangl@iastate.edu.
<> <> <> <> <> <> <> <> <> <> <>
OUR LUCK HAS CONTINUED and her duties will be taken over by Dr. Zhiliang
Hu. Dr. Hu completed his Ph.D. at the University of Wisconsin and was a
postdoctoral research associate at both USDA-ARS MARC in Clay Center, NE
and at Iowa State University, Ames. We look forward to his help and input.
He can be reached at zlhu@iastate.edu.

NOW IS THE TIME TO MAKE YOUR HOTEL RESERVATIONS AND TRAVEL PLANS FOR PAGVI
meeting in San Diego. The Plant and Animal Genome VI will be January 18-22,
1998 and again will be in San Diego. Some excellent workshops have been
organized. Hotel accommodations for PAG-VI next January will be limited by
the Super Bowl following us into San Diego on the weekend after the
meeting. Those who wish to attend PAGVI will need to get their application
forms in promptly. If you missed PAGV, you can find the abstracts and
other information at: http://probe.nalusda.gov:8000/otherdocs/pg/pg5/
/allabstracts.html.
o o o o o o o o o o o
THE NEAL A. JORGENSEN TRAVEL AWARD will be presented to one graduate
student (not postdoc) from a U.S. laboratory to present a pig gene mapping
poster at the PAGVI meeting. The award is for $300 plus registration. To
apply, please send a cover letter and a copy of your abstract to the U.S.
Pig Genome Coordinator (fax: 515-294-2401) by November 5, 1997. A
committee will select the winner.
o o o o o o o o o o o
THE THIRD SET OF FLUORESCENTLY LABELED PRIMERS for pig microsatellites is
now ready for distribution. This third set is composed of 53 pairs of
fluorescent primers and brings the total number of fluorescent primer pairs
distributed by the U.S. Pig Genome Coordinator to 149 pairs (for more
details see last newsletter). In addition, a differential display primer
set consisting of 10 oligo-dT anchor antisense primers with different
2-base extensions on the 3' end, and 20 arbitrary 10-mer sense primers
(5'), yielding a total of 200 primer combinations for screening cDNA
populations. To request either set of primers, please contact the U.S. Pig
Genome Coordinator at mfrothsc@iastate.edu. Funds for these materials are
provided by the USDA-CSREES Pig Genome Coordination Project. Suggestions
to produce additional primer pairs are still welcome.

IT IS NOT TOO LATE TO PLAN TO GO TO ARMIDALE. THE 6TH WORLD CONGRESS on
Quantitative Genetics Applied to Livestock Production meets January 10-16
in Armidale, Australia. Gene mapping and QTL sessions are planned.

IT IS EARLY BUT PLANS FOR THE 1998 ISAG CONFERENCE are underway and are
included in the ISAG (International Society for Animal Genetics) web site
(http://www.wisc.edu/animalsci/isag/index.html). The 1998 conference will
take place from August 9-14, 1998 in Auckland, New Zealand.
<> <> <> <> <> <> <> <> <> <> <>
NEED SOME HELP TO TRAVEL this next year? As in the past, some limited
assistance may be available for active U.S. pig genome members to travel to
the ISAG meeting in New Zealand. If you hope to go and need some
assistance, please contact the U.S. Pig Genome Coordinator soon.
