Cytogeographic study of the genus paris
WebThe Genus Paris L., distributed in Europe and Asia, is one of the genera of Trilliaceae. There are currently 19 recognized species. The karyological study indicates that basic number of the Paris species is X=5, and here are two kinds of the basic karyotypes: tropical type (K2n=2x=10=6m+4t), and temperate type (K2n=2x=10=6m+4st, or 6m+ 2st+2t). WebJul 13, 2011 · The base chromosome number (x) for Nicotiana is 12 and the genus is currently divided into eight diploid sections, where n = 9, 10 or 12, and five allopolyploid sections, where n = 24 (Olmstead et al. 1999 ). Section Suaveolentes is the sole exception to this pattern because of its wide range of chromosome numbers.
