Premise of the study:Begonia fimbristipula (Begoniaceae) is a medicinal herb distributed in the Chinese provinces of Fujian, Guangdong, Guangxi, Hainan, Hunan, Jiangxi, and Zhejiang, and it is on the verge of extinction due to habitat destruction and deterioration of its ecosystem. Here we developed a set of highly polymorphic microsatellite markers for population genetic and conservation studies of this endangered medicinal plant.Methods and Results:Using the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) protocol, 18 polymorphic microsatellite markers were identified within 48 individuals from two geographic locations. The observed and expected heterozygosities ranged from 0.208 to 1.000 and from 0.291 to 0.812, respectively. These microsatellite markers were cross-amplified in five related Begonia species, and six loci were successfully amplified in all species.Conclusions:These 18 markers will be useful for better conservation and utilization of wild resources of B. fimbristipula and other Begonia species in the future.

Studies have found that green practices can help organization create unique competitive advantages, such as enhancing the brand value. However, in the existing research, people did not know much about the exhibition audiences’ perceptions of green practices, or its impact on brand loyalty. This study explores the dimension of green practice perceptions of exhibition audiences, uses the trust-commitment theory to verify the relationship between green practice perceptions and exhibition brand loyalty. A total of 665 valid questionnaires were collected in the two exhibitions. The results show that four of the five types of green practices perceived by the audience will significantly affect green trust and then brand loyalty through commitment. Two of the five types of green practice perception can directly affect brand loyalty. And green self-identity will significantly adjust the relationship between green trust and affective commitment. Finally, suggestions are proposed for academic and practical reference.
