Genetic diversity of the Arctic fox using SRAP markers

M. Zhang and Bai, X. J., “Genetic diversity of the Arctic fox using SRAP markers”, vol. 12, pp. 6176-6183, 2013.

Sequence-related amplified polymorphism (SRAP) is a recently developed molecular marker technique that is stable, simple, reliable, and achieves moderate to high numbers of codominant markers. This study is the first to apply SRAP markers in a mammal, namely the Arctic fox. In order to investigate the genetic diversity of the Arctic fox and to provide a reference for use of its germplasm, we analyzed 7 populations of Arctic fox by SRAP.

Molecular characterization of urdbean (Vigna mungo) germplasm related to resistance against urdbean leaf crinkle virus

R. Binyamin, M. Khan, A., Khan, A. I., M. Khan, A., Awan, F. S., and Khan, N. A., “Molecular characterization of urdbean (Vigna mungo) germplasm related to resistance against urdbean leaf crinkle virus”, vol. 10, pp. 1681-1688, 2011.

Urdbean (Vigna mungo) is an important pulse crop grown worldwide. Urdbean leaf crinkle virus (ULCV) is a pathogen of urdbean found in Pakistan that causes huge losses in yield. Forty urdbean varieties/lines were screened against the virus under field conditions during spring season 2009. None of the lines appeared to be highly resistant or resistant. On the basis of a 0-5 disease rating scale and disease severity index, genotypes varied significantly in their reaction to ULCV.

Genetic diversity in tetraploid switchgrass revealed by AFLP marker polymorphisms

J. Todd, Wu, Y. Q., Wang, Z., and Samuels, T., “Genetic diversity in tetraploid switchgrass revealed by AFLP marker polymorphisms”, vol. 10, pp. 2976-2986, 2011.

Switchgrass (Panicum virgatum) is a perennial warm-season grass native to North America that has been identified as a dedicated cellulosic biofuel crop. We quantified genetic diversity in tetraploid switchgrass germplasm collected at Oklahoma State University and characterized genetic relatedness among the collections from distinct regions. Fifty-six tetraploid accessions, including seven upland and 49 lowland genotypes from throughout the US, were examined.
