description

Abstract The Centaurea parlatoris group belongs to sect. Dissectae and is one of the most taxonomically critical groups in Sicily. The taxa included in it inhabit dry slopes, pastures and rocky places. Some of them are narrow endemics to Sicily, and others to Italy. The great morphological variability at the intrapopulation level has not permitted the creation of an adequate taxonomic scheme. The recent proposal of two new species from Sicily confirms the insufficient knowledge of the taxonomic diversity. This study involves eight Sicilian populations of the C. parlatoris group. Seven loci from nine enzyme systems [isocitrate dehydrogenase (IDH), malate dehydrogenase (MDH), 6-phosphogluconate dehydrogenase (6-PGD), phosphoglucomutase (PGM), alcohol deydrogenase (ADH), shikimate deydrogenase (SKD), leucine aminopeptidase (LAP), glutamate-oxaloacetate transaminase (GOT) and phosphoglucoisomerase (PGI)] were examined. A total of 23 alleles were identified; seven were fixed in different populations, others we...
