Abstract:

Pollen plays important roles in the reproduction and gene flow of flowering plants, and its haploid DNA sequence provides useful information for studies of plant evolution and genealogy. We describe a new method for multiple microsatellite genotyping and DNA sequencing from a single pollen grain. The haploid DNA was extracted from a single pollen grain by using a simple DNA extraction method, and multiple microsatellite genotypes and DNA sequences of multiple chloroplast loci were determined. Using nine pairs of microsatellite primers, more than 90% of genotypes were successfully determined, and 71% and 100% of DNA sequences were determined at two chloroplast DNA loci, the trnL intron region and the trnL/trnF intergenic spacer region, respectively. This simple method of genetic analysis for a single pollen grain will facilitate detailed study of pollination, evolution and genealogy.
