The giant fennel, Ferula communis L. (Apiaceae) is a circum-Mediterranean species responsible of severe haemorrhagic intoxication of livestock. Electrophoretic analysis of 14 putative enzyme loci was carried out to assess genetic differentiation among poisonous and non-poisonous chemotypes of F. communis in Sardinia. Genetic structuring characterises all the five populations examined. However, differentiation was higher between poisonous and nonpoisonous populations (P < 0.00001), and was independent from geographic distances, suggesting a reduced gene flow between the two chemotypes.

Abstract
The giant fennel, Ferula communis L. (Apiaceae) is a circum-Mediterranean species responsible of severe haemorrhagic intoxication of livestock. Electrophoretic analysis of 14 putative enzyme loci was carried out to assess genetic differentiation among poisonous and non-poisonous chemotypes of F. communis in Sardinia. Genetic structuring characterises all the five populations examined. However, differentiation was higher between poisonous and nonpoisonous populations (P < 0.00001), and was independent from geographic distances, suggesting a reduced gene flow between the two chemotypes.
