Premise Of The Study:
Microsatellite markers were identified for Melastoma tetramerum var. tetramerum (Melastomataceae), a critically endangered shrub endemic to the Bonin Islands, to reveal genetic characteristics in wild and restored populations.
Methods And Results:
Using next-generation sequencing, 27 microsatellite markers were identified. Twenty of these markers were polymorphic in M. tetramerum var. tetramerum, with two to nine alleles per locus and expected heterozygosity ranging from 0.10 to 0.71. Among the 20 polymorphic markers, 15 were applicable to other closely related taxa, namely M. tetramerum var. pentapetalum, M. candidum var. candidum, and M. candidum var. alessandrense.
Conclusions:
These markers can be potentially useful to investigate the genetic diversity, population genetic structure, and reproductive ecology of M. tetramerum var. tetramerum as well as of the three related taxa to provide appropriate genetic information for conservation.
