Project funding

This project is an INRA-RFBR collaborative project. Funding for sequencing of BAC contigs has been provided from the Genomics, Proteomics, and Bioinformatics Program of the Siberian division of RAS.

Abstract

Chromosome 5B is nearly 870 Mbp (5BL = 580 Mbp and 5BS = 290 Mbp) and is known to carry important genes such as Ph1 involved in homoeologous pairing, Skr and Kr1 involved in intergeneric crossability of wheat and many others. The INRA-RFBR collaborative project aims at contributing to develop an integrated physical map of chromosome 5B which will provide a platform for map-based cloning of genes of agronomic interest located on this chromosome, support marker assisted selection and sequencing chromosome 5B as part of the International Wheat Genome Sequencing Consortium effort to develop a genome sequence-.based platform for wheat improvement ( www.wheatgenome.org ). The specific goals of the 2 years INRA-RFBR collaborative project are to collect and develop molecular markers on chromosome 5B, develop populations and genetic maps for chromosome 5B that will be ready for anchoring the physical map when available, train the Russian partner in physical map construction and marker development and support the map based cloning of a crossability gene on 5BS. In addition, sequencing of 10 BACs is underway in collaboration with the Scientific Research Institute of Physical-Chemical Medicine in Moscow.
