Collaboration on Sustainable Wheat Production

16 January 2014

UK - Axiom Wheat Genotyping Array (Axiom Wheat Array), consisting of 817,000 markers, was designed for the University of Bristol as part of the Biotechnology and Biological Sciences Research Council (BBSRC)-funded Wheat Improvement Strategic Program (WISP).

The aim of WISP is to produce new and novel wheat germplasm via three complementary ‘pillars’ (landraces, synthetics, and ancestral gene introgression), each of which will broaden the pool of genetic variation in elite wheat cultivars by a different route.

The design of Axiom Wheat Array is unique because it includes functional and positional annotation information for a variety of wheat species.

The SNPs (DNA sequence variations) on Axiom Wheat Array include markers from hexaploid landraces and those from the synthetic and ancestral lines exhibiting different ploidy levels. Results from the array will be presented at the 2014 Plant and Animal Genome conference (PAG XXII), in San Diego, California.

"The results from Axiom Wheat Array are fantastic and have helped WISP achieve one of the main goals, which is to track the different segments of the 'wheat relative' line and incorporate them into hexaploid bread wheat through the breeding process. The follow-on focused arrays will offer wheat breeders the capability to understand polymorphisms between their current breeding lines," stated Professor Keith Edwards, project leader and professor of Cereal Functional Genomics at the School of Biological Sciences and a member of the University’s Cabot Institute.

"We were thrilled to be able to complete the design and analysis in less than three months and in time to present the results at the Plant and Animal Genome meeting. This was made possible mainly because of the expertise, commitment, and collaborative efforts of the bioinformatics and product support teams at Affymetrix."

"We are pleased to be able to support the goals of the University of Bristol and contribute efforts to help sustain wheat production in the face of challenges from a growing world population and climate change," said Dr Andy Last, Executive Vice President and Chief Operating Officer at Affymetrix.

"The Axiom platform enables researchers to publish results sooner and breeders to accelerate their genomic programmes. The platform’s superior capabilities are transforming and modernising custom genotyping capabilities accessible to the agricultural, scientific, and applied community at large."
