Large Differences in Genetic Variation of Multigene Families in Barley
Journal of Heredity
A preliminary survey of restriction fragment length polymorphisms in barley (Hordeum vulgare ssp. vulgare) and wild barley (H. vulgare ssp. spontaneum) showed large differences in the levels of variation between a number of multigene families in accessions that originated in the primary center of diversity around the eastern Mediterranean. The high pl α-amylase, alcohol dehydrogenase, and hordein C gene families showed high levels of variation, but, in contrast, the low pl α-amylase and waxy gene families were more conserved. The more conserved low pl α-amylase and waxy genes may be due to small sample size, but other factors such as selection may be responsible for these differences.
