Next-generation RNA sequencing analysis was performed to develop 13 novel expressed sequence tag–simple sequence repeat markers to evaluate the genetic variation in the near-threatened halophyte Limonium tetragonum (Thunb.) A. A. Bullock. In the four populations examined, the total number of alleles at each locus ranged from two to seven, with an average of 3.1. The average observed and expected heterozygosity ranged from 0.00 to 0.13 and 0.28 to 0.78, respectively. Three of the 13 loci had the same homozygous alleles within populations, but different alleles among populations. Compared to other halophytes, relatively low genetic diversity was observed in this species. Further studies are necessary to determine the population demography of L. tetragonum and to clarify the cause of its low genetic diversity.
