Isozyme analysis of genetic diversity in wild Sicilian populations of Brassica sect. Brassica in view of genetic resources management
2004
In Sicily and in the small surrounding islands the section Brassica of the genus Brassica comprises five species, B. insularis Moris, B. incana Ten., B. macrocarpa Guss., B. rupestris Raf. and B. villosa Biv. These taxa represent a genetic resource as relatives of kale crops but some populations are endangered or threatened, thus isozyme analyses were performed to assess the genetic diversity degree at population and species levels in order to assist the design of conservation management programs. Eleven loci from five enzyme systems (aconitase, leucine aminopeptidase, 6-phosphogluconate dehydrogenase, phosphoglucoisomerase phosphoglucomutase) were analyzed in sixteen natural population (fi…
The Sicilian wild cabbages as biological resources: taxonomic update and a review on chemical constituents and biological activities
2020
Considering the growing interest that wild brassicas have as sources of bioactive molecules as well as a genetic resource, the authors review and update the taxonomy of Brassica sect. Brassica, limited to the native flora of Sicily, an island considered to be an active diversification center for the group of species of the aforementioned section. Regarding the taxonomic aspects, Brassica tardarae is here considered a subspecies of B. rupestris; the distinction at the subspe- cific level of B. raimondoi, a critical taxon included in B. incana, is also confirmed. In addition, two new subspecies are proposed, respectively in B. incana and B. rupestris. The taxonomic information relating to the…
