【中文摘要】 Three types of molecular markers (SRAP, ISSR and RAPD) were used to identify four Tremella fuciformis strains, T6 (white), T7 (white), T8 (yellow) and T9 (light yellow). Twelve SRAP primer pairs, ten ISSR primers and eight RAPD primers were screened, and identification data obtained using the three molecular markers were consistent in that the four T. fuciformis strains were divided into three groups with T7 and T9 clustered together in a single group. Each RAPD primer generated a higher average...更多 number of polymorphic bands than either the SRAP or ISSR primers, and the average similarity between the four strains was 81.34%. SRAP markers reflected more genetic information compared with the two other markers, and the average similarity was 68.98%. Genetic information reflected by ISSR markers was intermediate between SRAP and RAPD, and the average similarity was 77.48%.  還原
