Sex differential marker FD for rapid sex identification of Litsea cubeba

Q. Wu, Chen, Y., Wang, Y., and Lin, L., Sex differential marker FD for rapid sex identification of Litsea cubeba, vol. 14, pp. 12820-12827, 2015.

Litsea cubeba is an important economic tree in China. Sex identification of the species is required to reduce breeding costs. Molecular biology is an ideal method to achieve this aim because of the lack of morphological differences between male and female plants, especially at the seedling stage. Sequence-related amplified polymorphism was used to amplify sex-related bands. Following sequencing, the amplified fragment Dwas used to create a sequence-characterized amplified region (SCAR) marker, FD.

Genetic diversity and relationship of chicory (Cichorium intybus L.) using sequence-related amplified polymorphism markers

X. Y. Liang, Zhang, X. Q., Bai, S. Q., Huang, L. K., Luo, X. M., Ji, Y., and Jiang, L. F., Genetic diversity and relationship of chicory (Cichorium intybus L.) using sequence-related amplified polymorphism markers, vol. 13, pp. 7736-7746, 2014.

Chicory is a crop with economically important roles and is cultivated worldwide. The genetic diversity and relationship of 80 accessions of chicories and endives were evaluated by sequence-related amplified polymorphism (SRAP) markers to provide a theoretical basis for future breeding programs in China. The polymorphic rate was 96.83%, and the average polymorphic information content was 0.323, suggesting the rich genetic diversity of chicory. The genetic diversity degree of chicory was higher (GS = 0.677) than that of endive (GS = 0.701).

Comparative analysis of genetic diversity among species of Chrysanthemum and its related genera using inter-simple sequence repeat and sequence-related amplified polymorphism markers

X. Zhang, Zhang, F., Zhao, H., Guan, Z., Chen, S., Jiang, J., Fang, W., and Chen, F., Comparative analysis of genetic diversity among species of Chrysanthemum and its related genera using inter-simple sequence repeat and sequence-related amplified polymorphism markers, vol. 13, pp. 8469-8479, 2014.

In this study, inter-simple sequence repeats (ISSRs) and sequence-related amplified polymorphism (SRAP) were applied to assess the genetic diversity in 38 species of Chrysanthemum and related genera. A total of 204 and 567 bands were amplified by 24 ISSR and 25 SRAP primers, of which 196 (97%) and 557 (99%) were polymorphic, respectively. The ISSR-based genetic similarity ranged from 0.016 to 0.886 and averaged 0.201, while the SRAP-based genetic similarity varied from 0.010 to 0.811 and averaged 0.122.

Genetic diversity and relationships in cultivars of Lolium multiflorum Lam. using sequence-related amplified polymorphism markers

L. K. Huang, Jiang, X. Y., Huang, Q. T., Xiao, Y. F., Chen, Z. H., Zhang, X. Q., Miao, J. M., and Yan, H. D., Genetic diversity and relationships in cultivars of Lolium multiflorum Lam. using sequence-related amplified polymorphism markers, vol. 13, pp. 10142-10149, 2014.

Sequence-related amplified polymorphism (SRAP) markers were used to analyze and estimate the genetic variability, level of diversity, and relationships among 20 cultivars and strains of annual ryegrass (Lolium multiflorum Lam.). Eighteen SRAP primer combinations generated 334 amplification bands, of which 298 were polymorphic. The polymorphism information content ranged from 0.4715 (me10 + em1) to 0.5000 (me5 + em7), with an average of 0.4921. The genetic similarity coefficient ranged from 0.4304 to 0.8529, and coefficients between 0.65 and 0.90 accounted for 90.00%.
