An optimized protocol for the development and discovery of polymorphic AFLP markers in tree species is described. The protocol was optimized for the production of fluorescently labeled PCR products and analysis using a capillary sequencer. This approach has been demonstrated to be efficient and reproducible for tree species with complex genomes. The most important modification was in the selective amplification step. Instead of using a traditional step down PCR, a fixed and higher annealing temperature was employed, improving the reproducibility and sensitivity of the protocol. The levels of polymorphisms detected with the optimized protocol on three woody species are in agreement with those previously reported in the literature for tree species. [ABSTRACT FROM AUTHOR]
