Endosperm Tolerance of Paternal Aneuploidy Allows Radiation Hybrid Mapping of the Wheat D-Genome and a Measure of γ Ray-Induced Chromosome Breaks

Creator:

Tiwari, Vijay K., Riera-Lizarazu, Oscar, Gunn, Hilary L., Lopez, KaSandra, Iqbal, M. Javed, Kianian, Shahryar F., and Leonard, Jeffrey M.

Abstract:

Physical mapping and genome sequencing are underway for the ≈17 Gb wheat genome. Physical mapping methods independent of meiotic recombination, such as radiation hybrid (RH) mapping, will aid precise anchoring of BAC contigs in the large regions of suppressed recombination in Triticeae genomes. Reports of endosperm development following pollination with...

Kumar, Ajay, Bassi, Filippo M., Paux, Etienne, Al-Azzam, Omar, de Jimenez, Monika Michalak, Denton, Anne M., Gu, Yong Q., Huttner, Eric, Kilian, Andrzej, Kumar, Sachin, Goyal, Aakash, Iqbal, Muhammad J., Tiwari, Vijay K., Dogramaci, Munevver, Balyan, Harindra S., Dhaliwal, Harcharan S., Gupta, Pushpendra K., Randhawa, Gursharn S., Feuillet, Catherine, Pawlowski, Wojciech P., and Kianian, Shahryar F.

Abstract:

Background: The uneven distribution of recombination across the length of chromosomes results in inaccurate estimates of genetic to physical distances. In wheat (Triticum aestivum L.) chromosome 3B, it has been estimated that 90% of the cross over events occur in distal sub-telomeric regions representing 40% of the chromosome. Radiation hybrid...
