Preliminary genetic analysis of conchocelis from 5 Porphyraspecies using microsatellite

    Abstract
  • We conducted a preliminary genetic analysis of conchocelis from 5Porphyra species (P.haitanensis, P.katadai, P.yezoensis, P.oligospermatangia and P.crispate) by 68 microsatellite primer-pairs, and selected 20 microsatellite primer-pairs with high polymorphism. The polymorphism proportion among 10 Porphyra conchocelis reaches 95.24%, and the effective number of alleles for each primer is 1.22~4.05 (average 2.37). The genetic diversity index is 0.254 6~0.899 4 and the genetic distance between different species is 0.106 0 ~1.406 6. Conchocelis from the same species fgroup into one cluster first, which reveals that the selected microsatellite primer-pairs have good genetic resolution power.
