ISOLATION AND CHARACTERIZATION OF MICROSATELLITE LOCI IN AN ENDANGERED PALM, JOHANNESTEIJS']JSMANNIA LANCEOLATA (ARECACEAE)

. Premise of the study: Microsatellite markers were developed for Johannesteijsmannia lanceolata to assess the genetic diversity and mating system of this alarmingly endangered species. . Methods and Results: A total of 31 polymorphic microsatellite markers were developed for J. lanceolata using the enrichment protocol. These markers were screened on 24 samples from a natural population. The number of alleles ranged from four to 20, while the observed heterozygosity ranged from 0.391 to 1.000. The 31 loci were further tested for transferability on J. altifrons, J. magnifica, and J. perakensis. Generally, all loci showed positive amplifications in these three Johannesteijsmannia species, except Jla 124 (J. magnifica) and Jla 168b (J. magnifica and J. perakensis). . Conclusions: These microsatellite markers could be employed to study the population genetics and mating system of J. lanceolata and other Johannesteijsmannia species.
