| spatial genetic structure in wild cardoon, the ancestor of cultivated globe artichoke: limited gene flow, fragmentation and population history. | nuclear and chloroplast markers and phenotypic characters were integrated to analyse the population genetic structure of wild cardoon, cynara cardunculus var. sylvestris, the ancestor of cultivated globe artichoke, cynara cardunculus var. scolymus on the island of sardinia, italy. the spatial scale ranged from a few metres to ∼200km. wild cardoon appears to be genetically fragmented, with significant genetic divergence at various scales, indicating that gene flow is insufficient to counterbalanc ... | 2016 | 27968988 |
