摘要
In this paper we present a simple and reliable method for the extraction of nuclear DNA from grains of herbarium specimens of emmer wheat, along with a method to determine the level of DNA preservation with a set of PCR primers based on the nuclear high-molecular-weight glutenin gene. The method gave PCR products of between 80 and 1,030 bp. PCR products from each set of amplification reactions were cloned and sequenced in order to confirm their identity. We have found excellent levels of DNA preservation in grain between 49 and 107 years old, consistently amplifying products of at least 350 bp.
