Rice grasshopper, Oxya japonica, is one of the most important pests in south China, mainly inhabiting fields of wild rice (Oryza rufipogon) and cultivated rice (Oryza sativa). In this study, we used AFLP marker to investigate the genetic diversity and population structure of rice grasshoppers collected from south China, with emphasis on testing the hypothesis that there was significant genetic differentiation...
Genetic diversity within and among 10 mangrove and non-mangrove populations of Heritiera littoralis from three sites in China and one site in Australia was determined using inter-simple sequence repeats (ISSR). Eleven primers produced 173 bands across a total of 166 individuals. At the species level, genetic diversity was high (P=93.1%, He=0.24, and I=0.37). Higher genetic diversity was observed in...
