title: PCR and sequencing from a single pollen grain.
abstract: In order to eliminate the laborious step of DNA extraction preceding all studies within the field of plant molecular biology we attempted to do PCR amplifications directly on pollen grains. Successful PCR amplification was obtained in reactions including a single pollen grain from Hordeum vulgare or Secale strictum. Both the plastid gene encoding ribulose-1,5-biphosphate carboxylase/oxygenase (rbcL) and the nuclear-encoded internal transcribed spacer regions (ITS) and the 5.8S rDNA region were amplified and sequenced to verify PCR amplification.
