| allozyme variation among six populations of the freshwater-snail oncomelania hupensis in zhejiang, china. | thirteen enzymes encoded by 16 loci of six population of oncomelania hupensis in zhejiang, china, were investigated by means of starch gel electrophoresis. ten loci (ao, 6pgd, me, akp, oct-1, hbdh-1, hbdh-2, xdh, mdh and mpi) were monomorphic and 6 loci (oct-2, pgi, aat, pgm-1, pgm-2 and acp) were polymorphic. three enzymes (oct, hbdh and pgm) were encoded by 2 loci. the results indicated that there were allozyme variations in two subspecies, o.h. hupensis and o.h. fausti in zhejiang, china. nei ... | 1996 | 9280011 |
| landscape genetics: the correlation of spatial and genetic distances of oncomelania hupensis, the intermediate host snail of schistosoma japonicum in mainland china. | two internal transcribed spacer (its1 and its2) sequences of the non-coding region of the rdna and a 16s rna gene fragment of the mtdna of oncomelania hupensis, the intermediate host snail of schistosoma japonicum in mainland china, have been investigated with a view to illustrate the influence of the environment on genetic differentiation. thirteen populations of o. hupensis snails, representing four types of ecological settings, were collected to compare genetic and spatial distances. the leng ... | 2009 | 19440964 |
