Genetic structure of the threatened Hopea chinensis in the Quang Ninh Province, Vietnam

N. T. P. Trang, Triest, L., Trang, N. T. P., and Triest, L., Genetic structure of the threatened Hopea chinensis in the Quang Ninh Province, Vietnam, vol. 15, p. -, 2016.

Hopea chinensis Hand-Mazz (synonym H. hongayensis Tardieu), is a wind and insect pollinated species. It is a threatened species known only from two locations: Quang Ninh (Vietnam) and Guangxi (China). As an endemic species, it is worth preserving both for dipterocarp biodiversity, as well as for its medicinal use and economic importance as a fine wood. The genetic diversity and population genetic structure of H. chinensis was investigated, using natural populations distributed throughout the Ba Mun and Cai Lim islands, Quang Ninh Province, Vietnam.

Development and characterization of microsatellite markers for Ulmus chenmoui (Ulmaceae), an endangered tree endemic to eastern China

S., and Liu, H., Development and characterization of microsatellite markers for Ulmus chenmoui (Ulmaceae), an endangered tree endemic to eastern China, vol. 15, p. -, 2016.

Ulmus chenmoui (Ulmaceae) is an endangered tree found on Langya Mountain, eastern China. To better understand the population genetics of U. chenmoui and conserve the species, we developed microsatellite markers. Using a suppression-polymerase chain reaction technique, 74 compound microsatellite primer pairs were designed. Twelve microsatellite markers were polymorphic in 39 individuals, and the number of alleles per locus ranged from 3 to 9. The observed and expected heterozygosities ranged from 0.051 to 0.769 and from 0.533 to 0.768, respectively.
