Forty-six microsatellite loci were selected for further genotyping in 12 S. aspera populations. The number of alleles varied from three to 28, and 93.5% of the developed microsatellite markers could be cross- amplified in least one of three congeneric Smilax species. • Conclusions: The SSR markers developed in this study will facilitate further studies on genetic diversity and phylogeographic patterns of S. aspera in intercontinental geographical scales. Key words: deep lineage divergence; intercontinental disjunction; microsatellites; Smilacaceae; Smilax aspera; Tethyan veg- etation; transcriptome. Smilax aspera L. (Smilacaceae) is a prickly woody climber insights into intra- and interpopulation gene flow and genetic with sclerophyllous leaves, small dioecious flowers, and fleshy drift. Therefore, more efficient codominant markers such as mi- red berries. This species is widespread throughout the circum- crosatellites should be developed to allow further study. Mediterranean region and has a disjunct distribution into the Xu et al. (2011) reported 14 simple sequence repeat (SSR) East African upland evergreen forest and South Asian seasonal markers of S. aspera developed in Greek and Italian popula- forest. With its Tethyan disjunction pattern, S. aspera represents tions using dual-suppression PCR, but three of the published an ideal model to test the dynamics and evolutionary history primers were not polymorphic. Also, through subsequent cross- of laurel forests in the Late Tertiary period (Mai, 1995; Chen population amplification investigation in eight populations from et al., 2014). A previous phylogeographic study (Chen et al., Africa, Asia, and the Mediterranean, they showed lack of univer- 2014) detected a deep lineage split between Mediterranean and sality. Our testing of these markers showed average amplification African-Asian populations of S. aspera and a complex biogeo- efficiency of 48.8%, and 71.4% of the markers had amplifica- graphical range evolution history based on cpDNA and ITS se- tion efficiency below 60%. Hence more reliable microsatellite quences. However, these markers could not reveal the recent markers are needed. Here, we developed 46 variable microsat- gene flow by pollen dispersal, and they did not provide detailed ellite markers for S. aspera based on transcriptome data of S. bona-nox L.
