Utilization of PCR primers for wheat storage protein genes in population genetic analysis

摘要

Increasing knowledge concerning gene sequence and structure is providing new and more vigorous tools for analyzing variations in natural populations. Sequences of Triticum genes coding for seed storage proteins were used to study the genetic structure of 25 populations of Triticum trugidum subsp. dicoccoides from the Fertile Crescent. A surprisingly wide within-population variation was detected. in addition to the variation among populations already documented. Diversity was found to be associated with environmental factors such as climate and soil variation, confirming that this variation does not occur at random but is the result of natural selection.
