Abstract

Polyploidy is a prominent process in plants and has been significant in the evolutionary history of vertebrates and other eukaryotes Polyploidy induces genomewide duplication Studies on nucleotide diversity at homoeologous loci may provide insight into the evolutionary dynamics of duplicate genes In the present study we estimated the levels and patterns of nucleotide diversity for alcohol dehydrogenase 1 adh1 loci in three American allotetraploid Oryza species O alta O grandiglumis and O latifolia Higher nucleotide diversity was revealed in the C genome This result suggested the different evolutionary dynamics of homoeologous adh1 loci in these allotetraploid Oryza speciesWe thank RenHua Wu YanPing Hu ZhaoShan Wang YongTing Ma Ping Liu XiuHua Xue YiHua Xiao and WenFeng Tu for their technical assistance and the International Rice Research Institute Manila Philippines for providing seed samples The work was supported by the National Natural Science Foundation of China 30470124 30770145 Program for New Century Excellent Talents in University NCET060609 Doctoral Research Fund for Shandong Province 2007BS08020 The Project of Key Disciplines of Shandong Province and The Project Sponsored by the Scientific Research Foundation for the Doctors Qufu Normal University
