Efficiency of semi-automated fluorescent multiplex PCRs with 11 microsatellite markers for genetic studies of deer...

Thirty bovine and eight ovine microsatellite primer pairs were tested on four tropical deer species: Eld's and Swamp deer (highly threatened) and Rusa and Vietnamese Sika deer (economically important). Thirty markers gave an amplified product in all four species (78.9%). The number of polymorphic microsatellite markers varied among the species from 14 in Eld's deer (47%) to 20 in Swamp deer (67%). Among them, 11 microsatellite loci were multiplexed in three polymerase chain reactions (PCRs) and labelled with three different fluorochromes that can be loaded in one gel-lane. To test the efficiency of the multiplex, primary genetic studies (mean number of alleles, expected heterozygosities and Fis values) were carried out on four deer populations. Parentage exclusion probability and probability of identity were computed and discussed on a Swamp deer population. These multiplexes PCRs were also tested on several other deer species and subspecies. The aim of this study is to establish a tool useful for genetic studies of population structure and diversity in four tropical deer species which with few modifications can be applied to other species of the genus Cervus.
