Development of EST-SSR and TRAP markers from transcriptome sequencing data of the mango

Genet Mol Res. 2015 Jul 14;14(3):7914-9. doi: 10.4238/2015.July.14.17.

Abstract

Mango is one of the most commercially important fruit crops in tropical and subtropical regions. To increase the efficiency of breeding strategies, two EST-derived marker systems were developed in the present study using information from the mango fruit transcriptome. Using simple sequence repeats, 218 of 230 primer pairs showed stable amplification for 7 mango genotypes with amplicons ranging from 84 to 160 bp; 93 of the primer pairs yielded polymorphic products. The proportion of polymorphic bands ranged from 16.67 to 100%, with a mean of 55.64%. In contrast, 86 primer pairs exhibited good amplification with clear bands for target region amplification polymorphism analysis, and a total of 66 primer combinations were polymorphic. These two novel sets of EST-derived markers will be of use in future studies of genetic diversity, genetic map construction, and marker-assisted selection in mango.
