Abstract

Simple sequence repeat (SSR) enriched libraries for five groups of tropical perennial plants with edible fruits and shoots were prepared and sequenced in a GS-FLX Roche 454: sapodilla (Manilkara zapota (L.) P. Royen), lychee (Litchi chinensis Sonn.), mangosteen (Garcinia mangostana Linn. and G. cochinchinensis (Lour.) Choisy), rambutan (Nephelium lappaceum L.), and bamboo (Bambusa vulgaris Schrad. ex J.C. Wendl and Guadua angustifolia Kunth). For SSR development, these species were organized by their common names in five groups. A total of 3870 SSR primer sets were designed, using capillary electrophoresis 1872 nuclear SSRs were tested on 4 to 10 DNA samples within each plant group, that is 384 loci for each of the four groups of fruit trees and 336 loci for the bamboo group. Only 7.9% of the primers tested did not result in amplifi- cation. All 1872 SSRs are provided, we highlight 178 SSRs (between 26 and 47 per group) considered top-quality polymorphic SSRs that amplified all the samples, had strong fluorescence signal, presented no stutters and showed minimum non-specific amplification or background fluorescence. A total of 66,057 contig sequences were submitted to GenBank Database. Markers presented here will be useful not only for conservation efforts in banks of germplasm, but also for in-depth analysis of population genetics which usually requires evaluation of large number of loci.
