Z. Z. Xiao, Chen, W. W., Bao, W., Wang, R., Li, Y. Y., Xiao, Z. Z., Chen, W. W., Bao, W., Wang, R., and Li, Y. Y., Isolation and characterization of microsatellite loci in Quercus fabri (Fagaceae), vol. 15, p. -, 2016.

Quercus fabri is a pioneer species of secondary succession in evergreen broadleaved forests in China. In this study, we isolated and developed 12 polymorphic and 2 monomorphic microsatellite loci for Q. fabri using the biotin-streptavidin capture method. We characterized 12 polymorphic loci in 52 individuals from two populations. The number of alleles per locus ranged from 3 to 23. The observed and expected heterozygosities per locus were 0.033-0.773 and 0.138-0.924, respectively.

E. M. S. Souza, Pereira, G. S., Silva-Mann, R., Álvares-Carvalho, S. V., Ferreira, R. A., Souza, E. M. S., Pereira, G. S., Silva-Mann, R., Álvares-Carvalho, S. V., and Ferreira, R. A., A comparative framework of the Erythrina velutina tree species in reforested land and native populations, vol. 15, p. -, 2016.

Erythrina velutina Willd. (Fabaceae: Papillionoideae) is a pioneer species found in tropical and subtropical regions of the world that has medicinal properties and that is used in reforestation projects. This species is rare in some areas of northeastern Brazil. This study aimed to characterize and compare genetic structures of natural and restored populations of E. velutina, with a focus on the selection of tree seeds.

Analysis of genetic diversity of Brassica rapa var. chinensis using ISSR markers and development of SCAR marker specific for Fragrant Bok Choy, a product of geographic indication

M., Xue, J. Y., Li, M. M., Lin, Y. B., Sun, X. Q., and Hang, Y. Y., Analysis of genetic diversity of Brassica rapa var. chinensis using ISSR markers and development of SCAR marker specific for Fragrant Bok Choy, a product of geographic indication, vol. 15, p. -, 2016.

Non-heading Chinese cabbage [Brassica rapa var. chinensis (Linnaeus) Kitamura] is a popular vegetable and is also used as a medicinal plant in traditional Chinese medicine. Fragrant Bok Choy is a unique accession of non-heading Chinese cabbage and a product of geographic indication certified by the Ministry of Agriculture of China, which is noted for its rich aromatic flavor. However, transitional and overlapping morphological traits can make it difficult to distinguish this accession from other non-heading Chinese cabbages.

Structure of mitochondrial DNA control region and genetic diversity of Moschus berezovskii populations in Shaanxi Province

H. Feng, Feng, C. L., Huang, Y., Tang, J., Feng, H., Feng, C. L., Huang, Y., Tang, J., Feng, H., Feng, C. L., Huang, Y., and Tang, J., Structure of mitochondrial DNA control region and genetic diversity of Moschus berezovskii populations in Shaanxi Province, vol. 15, p. -, 2016.

In China, Moschus berezovskii (forest musk deer), a first-class national protected animal, was earlier widely distributed. However, wild populations of the forest musk deer have declined because of human activity and habitat loss. In order to gather useful information for its conservation and management, we investigated the genetic diversity and population structure of this species by analyzing a 632-bp fragment of mitochondrial DNA (mtDNA) control region in three wild populations in Shaanxi Province, China.

Bioinformatic analysis based on the complete coding region of the MSTN gene within and among different species

X. C. Song, Xu, C., Yue, Z. G., Wang, L., Wang, G. W., Yang, F. H., Song, X. C., Xu, C., Yue, Z. G., Wang, L., Wang, G. W., Yang, F. H., Song, X. C., Xu, C., Yue, Z. G., Wang, L., Wang, G. W., and Yang, F. H., Bioinformatic analysis based on the complete coding region of the MSTN gene within and among different species, vol. 15, p. -, 2016.

Myostatin, encoded by the MSTN gene (previously GDF8), is a member of the transforming growth factor-β superfamily, which normally acts to limit skeletal muscle mass by regulating the number and growth of muscle fibers. In this study, a total of 84 myostatin gene sequences with known complete coding regions (CDS) and corresponding amino acid sequences were analyzed from 17 species, and differentiation within and among species was studied using comparative genomics and bioinformatics. Characteristics of the nucleotide and amino acid sequences were also predicted.

Isolation and characterization of microsatellite markers for Eucommia ulmoides (Eucommiaceae), an endangered tree, using next-generation sequencing

W. R. Zhang, Li, Y., Zhao, J., Wu, C. H., Ye, S., Yuan, W. J., Zhang, W. R., Li, Y., Zhao, J., Wu, C. H., Ye, S., Yuan, W. J., Zhang, W. R., Li, Y., Zhao, J., Wu, C. H., Ye, S., and Yuan, W. J., Isolation and characterization of microsatellite markers for Eucommia ulmoides (Eucommiaceae), an endangered tree, using next-generation sequencing, vol. 15, p. -, 2016.

Eucommia ulmoides Oliver, a single extant species of Eucommiaceae, is an endemic dioecious tree in China. The natural resources of E. ulmoides have rapidly declined in recent years because of the over-collection of its cortex. To design a suitable protection strategy, it is necessary to develop a set of molecular markers to investigate genetic diversity and population structure of E. ulmoides. Pyrosequencing of an enriched microsatellite library by Roche 454 FLX+ platform was used to isolate simple sequence repeats (SSRs) for E. ulmoides.
