Affymetrix Provides Highest Density Rice Genotyping Array for Identifying Unique Genetic Traits

Business Wire
Affymetrix, Inc. (NASDAQ:AFFX) today announced at the Plant and
Animal Genome XIX Conference (PAG) that it launched the GeneChip®
Rice 44K SNP Genotyping Array, the first high-density rice
genotyping array. This array was designed in collaboration with a
worldwide community of rice researchers to improve the rice
industry’s production confidence by providing a low-cost,
high-quality method for reliably identifying rice varietals and
examining the genetic inheritance of important agricultural
traits.
The GeneChip Rice 44K SNP Genotyping Array was developed in
collaboration with Dr. Susan D. McCouch, Professor in the
Department of Plant Breeding and Genetics at Cornell University, as
well as a team of scientists from world-renowned rice research
institutes and private sector partners. The array features more
than 44,000 SNPs and detects common genetic variants within and
between the major subpopulations of O. sativa, including indica,
aus, tropical japonica, temperate japonica, and aromatic, or Group
V.
“Our aim was to design an array dense enough to conduct
genome-wide association mapping studies and with the power to find
genes or loci underlying most phenotypes,” said Dr. McCouch. “The
beauty of Affymetrix’ Rice 44K SNP Genotyping Array is that it
enables us to explore quality and performance characteristics of
rice varieties all over the world, many of which are not well
known. Now their genomes are accessible.” Dr. McCouch will be
presenting her work at the PAG conference in San Diego.
With the Rice 44K SNP Genotyping Array, rice breeders for the
first time will be able to efficiently and cost-effectively
classify their germplasm as well as track and fingerprint varieties
for improved seed management, property protection, and patents. To
provide the rice community with access to this powerful technology,
Affymetrix has designated service providers who offer quality
assurance, quick turnaround time, affordable prices, and
confidentiality to researchers.
“We are pleased to have DNA Landmarks and Expression Analysis on
board as our service providers to conduct this important service
for the rice research community worldwide,” said Andy Last, Chief
Commercial Officer at Affymetrix. “This will quicken the discovery
of natural variation and quality characteristics impacting rice
production, which experts say must increase to keep pace with the
world’s growing population.”
The rice community’s project team, led by Dr. McCouch, also
included groups from the USDA’s Agricultural Research Service
(ARS), the National Rice Research Center in Stuttgart, Arkansas,
Stanford University’s Department of Genetics in Stanford,
California, and the International Rice Research Institute (IRRI) in
Los Banos, Philippines. The project was funded by the National
Science Foundation’s Plant Genome Research Program (Award
#0606461).
