Inter and intraspecific genetic diversity (RAPD) among three most frequent species of macrofungi (Ganoderma lucidum, Leucoagricus sp. and Lentinus sp.) of Tropical forest of Central India

Publication date: Available online 2 December 2017 Source:Journal of Genetic Engineering and Biotechnology Author(s): Sandhya Dwivedi, Surendra Singh, U.K. Chauhan, Mahendra Kumar Tiwari In present study seven RAPD primers were used to access the diversity within and among twelve populations of three mushroom species Ganoderma lucidum, leucoagaricus sp. and Lentinus sp. Total of 111 bands were scored by 7 RAPD primers in 30 accessions of three mushroom species collected from different sampling sites of central India. Total 111 bands were generated using seven primers which were F-1, OPG-06, OPC-07, OPD-08, OPA-02, OPD-02, OPB-10. All 111 bands were polymorphic in nature (100%). Therefore, it revealed that the used primers had sufficient potency for population studies and 30 accessions had higher genetic differences among each other. In best of the knowledge, this is the first report, which accesses the genetic diversity between three mushroom species (Gd Ganoderma lucidum, Lg Leucoagaricus sp., Ls Lentinus). The polymorphic percentage ranged from 3.60 to 23% within twelve populations, while polymorphic percentage among group was 40.56, among population within groups was 41.12 and within population was 18.32. This indicated that the genetic diversity within the population was very low, but slightly higher in the populations of three species. Among three groups representing Gd., Lg and Ls, Among populations within groups shown highest percentage of variation (Pv = 41....
