Premise of the study: We developed microsatellite markers to investigate the level of genetic diversity within and among populations of the endemic shrub Sauvagesia rhodoleuca in China. Methods and Results: Ten polymorphic microsatellite loci were identified in five populations. The number of alleles per locus varied from 2 to 16. Observed and expected heterozygosities ranged from 0.000 to 1.000 and from 0.000 to 0.726, respectively. Conclusions: The results provide basic information on genetic diversity for future studies of population genetics in S. rhodoleuca. © 2010 Botanical Society of America.

Allelopathy Journal | Year: 2010

Plant essential oils possess the biological activities, such as antibacterial, antifungal and antioxidant properties (12,14,15,26,50). The plant essential oils also exerted allelopathic effects on other plants (4,5,19,32,40). The Tagetes minuta and Schinus areira oils inhibits the root growth of Zea mays seedlings (38). Costunolide and parthenolide, isolated from the leaves of Magnolia grandiflora L, exhibited allelopathic potential on wheat (Triticum aestivum L.), lettuce (Lactuca sativa L.), radish (Raphanus sativus L.) and onion (Allium cepa L.) (2). Currently, the plant essential oils are being tried as potential candidates for weed (9), pest and disease management (1,20). The Eucalyptus urophylla is dominant specie in man-made forest communities in South China (23). However, in the past few years, there has been a growing concern on the excessive plantations of Eucalyptus which has decreased the biodiversity. Allelopathy is considered to be a major cause of understory suppression by Eucalyptus (25,27,29,46).

Eight microsatellite loci were isolated from enriched genomic libraries of Aquilaria sinensis (Lour.) Gilg. Thirty-one individuals from a wild population were tested for their polymorphisms. The number of alleles per microsatellite locus ranged from 4 to 10. The expected (H E) and observed (HO) heterozygosities varied from 0.4531 to 0.8372 and 0.4000 to 0.8710, respectively. These microsatellite markers will aid the investigation of the genetic variability and population structure in A. sinensis. © Springer Science+Business Media B.V. 2009.
