Spartina anglica C. E. Hubbard: a natural model system for analysing early evolutionary changes that affect allopolyploid genomes Copyright 2004 The Linnean Society of London KEYWORDS allopolyploidy • genome evolution • methylation-sensitive AFLP • multilocus markers • speciation ABSTRACT
Spartina anglica arose during the end of the 19th century in England by hybridization between the indigenous Spartina maritima and the introduced East American Spartina alterniflora and following genome duplication of the hybrid (S. × townsendii). This system allows investigations of the early evolutionary changes that accompany stabilization of a new allopolyploid species in natural populations. Various molecular data indicate that S. anglica has resulted from a unique parental genotype. This young species contains two distinctly divergent homoeologous genomes that have not undergone extensive change since their reunion. No burst of retroelements has been encountered in the F Received 16 June 2003; accepted for publication 5 January 2004 |
