Establishing a reservoir of polymorphic markers is an important key for marker-assisted breeding. Many crops are still lack of such genomic infrastructure. Single nucleotide polymorphisms (SNPs) and simple sequence repeats (SSRs) are useful as markers because they are widespread over the genome and many technologies were developed for high throughput genotyping. We present here a pipeline for developing a reservoir of SNP and SSR markers for Mangifera indica L. as an example for fruit tree crops having no genomic information available. Our pipeline includes de novo assembly of reference transcriptome with MIRA and CAP3 based on reads produced by 454-GS FLX technology; Polymorphic loci discovery by alignment of Illumina resequencing to the transcriptome reference; Identifying a subset of loci that are polymorphic in the entire germplasm collection for downstream diversity analysis by genotyping with Fluidigm technology.
