Evolutionary Biology of the Foxtail (Setaria) Secies-Group

摘要: The foxtails (Setaria spp.) are one of the worst weed groups interfering with U.S. and world agriculture land management (Holm et al., 1977, 1979, 1997), therefore world’s most successful terrestrial plant organisms. success is to a large extent due their intimate evolutionary relationship humans, disturbance, agriculture, management. invasive threat this group continues its increasing geographic range distribution, appearance new species biotypes, increase herbicide resistant variants. colonizing ability weedy buffered against change by accumulation dormant seed in soil banks, trait permitting enduring occupation locality.
