Population genetic structure of Myzus persicae nicotianae (Hemiptera: Aphididae) in China by microsatellite analysis

C. Zhao, Yang, X. M., Tang, S. H., Xu, P. J., Bian, W. J., Wang, X. F., Wang, X. W., and Ren, G. W., Population genetic structure of Myzus persicae nicotianae (Hemiptera: Aphididae) in China by microsatellite analysis, vol. 14, pp. 17159-17169, 2015.

The tobacco aphid, Myzus persicae nicotianae (Hemiptera: Aphididae), is an important agricultural pest that feeds on host plants and transmits plant viruses in China. To effectively control this pest, we investigated the genetic variation and genetic structure of 54 populations of tobacco aphids collected in China, using five microsatellite loci.

Genetic diversity in mutated and non-mutated rice varieties

M. Naeem, Ghouri, F., Shahid, M. Q., Iqbal, M., Baloch, F. S., Chen, L., Allah, S., Babar, M., and Rana, M., Genetic diversity in mutated and non-mutated rice varieties, vol. 14, pp. 17109-17123, 2015.

We studied the genetic variability due to mutation induced by γ-rays (10, 15, and 20 Kr) on various traits of twelve rice genotypes. Mutated and non-mutated seeds were sown in the field between July 2013 and 2014 using a split plot design. Yield and yield-related trait data was recorded, which showed significant (P < 0.05) genotypic and irradiation effects. Gamma radiation exerted non-significant effects on the panicle length of all plants, indicating the uniformity of performance of this character at different radiation levels.
