Biosystematics ofLobularia, Cruciferae, revisited: evidence from isozyme data

摘要: Abstract To obtain better insight in evolutionary processes, data on genetic diversity are compared with obtained by more traditional biosystematic methods. Altogether, ten isozymes 25 populations of Lobularia, Cruceferac, from Spain, Morocco, the Salvage Islands, Canary Islands and Cape Verde were screened starch gel electrophoresis. Genetic identities between pairs species low: 0.582 for canariensislibyca, 0.603 canariensis-maritima, 0.403 libyca-maritima. These biological species, i.e. isolated strong internal crossing barriers. The isozyme indicate that speciation is an old event genus. nine subspecies L. canariensis complex interfertile ecogeographical Among subspecies, ranged 0.476 to 0.846, a mean identity 0.734 all pairs. 22 canariensis, irrespective taxon, 0.456 0.961, ...
