Development of SNP-based dCAPS markers for identifying male sterile gene tms5 in two-line hybrid rice

F. S. Song, Ni, J. L., Qian, Y. L., Li, L., Ni, D. H., Yang, J. B., Song, F. S., Ni, J. L., Qian, Y. L., Li, L., Ni, D. H., and Yang, J. B., Development of SNP-based dCAPS markers for identifying male sterile gene tms5 in two-line hybrid rice, vol. 15, p. -, 2016.

Molecular markers can increase both the efficiency and speed of breeding programs. Functional markers that detect the functional mutations causing phenotypic changes offer a precise method for genetic identification. In this study, we used newly derived cleaved amplified polymorphic sequence markers to detect the functional mutations of tms5, which is a male sterile gene that is widely used in rice production in China.

Marker-assisted selection in breeding silkworm strains with high tolerance to fluoride, scaleless wings, and high silk production

M. W. Li, Yu, H. J., Yi, X. L., Li, J., Dai, F. Y., and Hou, C. X., Marker-assisted selection in breeding silkworm strains with high tolerance to fluoride, scaleless wings, and high silk production, vol. 14, pp. 11162-11170, 2015.

In the silkworm (Bombyx mori), tolerance to fluoride and scaleless wings are controlled by the dominant gene Dtf (dominant tolerance to fluoride) and recessive gene nlw (no Lepidoptera wings), respectively, and these genes have been mapped by using simple sequence repeat and sequence tag site markers. Marker-assisted evaluation and selection of silkworms with fluoride tolerance and scaleless wings were used for predicting fluoride resistance and scaleless wings in backcrossed animals.
