Genetic structures of Nibea albiflora as revealed by isozyme analysis

Abstract:

Horizontal starch gel electrophoresis was used to investigate the genetic structure 〖JP2〗and differentiation of the three〖JP〗 populations (Qingdao, Zhoushan and Xiamen) of Nibea albiflora. Eleven putative loci were revealed by eight enzymes (G3PDH, IDHP, LDH, MDH, PGDH, PGM, SDH and SOD). The percentage of polymorphic loci for each population was 02. The mean observed and expected heterozygosity ranged from 0010 1 to 0037 9 and from 0023 4 to 0039 9, respectively. The average number of efficient allele for each locus varied from 1.029 0 to 1.052 8. The genetic distances among populations were from 0.000 4 to 0.000 8, and the genetic similarities were from 0.999 2 to 0.999 6. The results showed that there was no significant genetic differentiation among the three populations of N. albiflora
