Extent and pattern of genetic differentiation within and between European populations of Phelipanche ramosa revealed by amplified fragment length polymorphism analysis

The extent and pattern of genetic differentiation between Phelipanche ramosa populations colonising tobacco in different European regions were investigated by amplified fragment length polymorphism (AFLP) analysis, in order to determine levels of variation for tobacco resistance breeding and management programmes. Four different AFLP primer pairs amplified a total of 1050 clear and reproducible bands, of which 962 (91.62%) were polymorphic among the 35 individuals taken from four P. ramosa populations collected in Spain, Italy, Bulgaria and Germany. Cluster analysis based on the AFLP data categorised the plants into distinct groups, in line with their geographical origin, denoting clear genetic differentiation among the four populations. This differentiation was supported by both high bootstrap values and significant results of the analysis of molecular variance. The most divergent population was the one from Bulgaria. The majority of the genetic diversity was attributable to differences among populations (77.80%), as expected from the predominant autogamous behaviour of this species. Populations differed significantly in within-population diversity, as measured by Shannon's information index. The German population presented the lowest genetic diversity and the Italian population harboured the highest level of within-population genetic diversity. There are significant differences in genetic diversity level among the studied P. ramosa populations and clear population-specific genetic diversity structures. These need to be taken into account, together with the potential differences in parasite aggressiveness, when planning breeding and management strategies for P. ramosa control in tobacco cultivation.
