Analysis of genetic diversity in Larix gmelinii (Pinaceae) with RAPD and ISSR markers

L. Zhang, Zhang, H. G., and Li, X. F., Analysis of genetic diversity in Larix gmelinii (Pinaceae) with RAPD and ISSR markers, vol. 12. pp. 196-207, 2013.

Dahurian larch (Larix gmelinii), a deciduous conifer, is the northernmost tree, native to eastern Siberia and nearby regions of China. We used growth traits and molecular markers to assess genetic variation in different L. gmelinii growing regions; 105 individual samples were collected from seven regions of the Qingshan Forestry Centre, Heilongjiang Province, China. The greatest genetic regional variation was seen in the Youhao area, based on coefficients of variation for tree height, diameter and volume (14.73, 28.25, and 55.27%, respectively).

Genetic diversity in wild Dipsacus chinensis populations from China based on ISSR markers

D. - X. Chen, Li, L. - Y., Zhang, X., Wang, Y., and Zhang, Z., Genetic diversity in wild Dipsacus chinensis populations from China based on ISSR markers, vol. 12, pp. 1205-1213, 2013.

Wild Dipsacus chinensis plants in China have become endangered owing to over-harvesting and habitat fragmentation. We examined the genetic diversity and genetic structure of 90 individuals from three populations using inter-simple sequence repeat markers and found that 106 of 173 bands amplified by 22 informative and reliable primers were polymorphic. These findings correspond to a medium level of genetic diversity.

Molecular characterization and phylogenetic relationships among species of the genus Brycon (Characiformes: Characidae) from four hydrographic basins in Brazil

R. S. P. Antunes, Gomes, V. N., Prioli, S. M. A. P., Prioli, R. A., Júlio, Jr., H. F., Prioli, L. M., Agostinho, C. S., and Prioli, A. J., Molecular characterization and phylogenetic relationships among species of the genus Brycon (Characiformes: Characidae) from four hydrographic basins in Brazil, vol. 9, pp. 674-684, 2010.

Brycon is one of the main genera of Neotropical freshwater fish. In Brazil, Brycon species have been found in many hydrographic basins, such as the Amazon, Paraná, Paraguay, and Araguaia-Tocantins basins. We examined the phylogenetic relationships among the species Brycon orbignyanus, B. hilarii, B. cf. pesu, B. cephalus, B. falcatus, and B. gouldingi, using mitochondrial and nuclear molecular markers. Specimens of B. orbignyanus were collected in the Paraná River. Specimens of B.

Molecular variability in Brycon cf. pesu Müller and Troschel, 1845 (Characiformes:Characidae) from the Araguaia-Tocantins Basin

R. S. Panarari-Antunes, Prioli, A. J., Prioli, S. M. A. P., Júlio, Jr., H. F., Agostinho, C. S., and Prioli, L. M., Molecular variability in Brycon cf. pesu Müller and Troschel, 1845 (Characiformes:Characidae) from the Araguaia-Tocantins Basin, vol. 7, pp. 95-106, 2008.

Brycon pesu is a small-sized fish distributed throughout the Amazon and Orinoco Basins and other coastal basins of northeastern South America. Brycon cf. pesu specimens from the Araguaia-Tocantins Basin are currently separated into two morphotypes, Brycon sp1 and Brycon sp2, owing to different coloration of their anal fin. Brycon sp2 has a reddish margin stripe on the anal fin which morphologically distinguishes it from Brycon sp1.
