Metabolic Properties

Abstract Chemical and genetic characterization of Veratrum species deposited in European collections is important for genepool preservation and identification of populations with desired metabolic properties. Veratrum album, V. lobelianum and V. nigrum are native to Europe, and in Poland are ranked as rare or threatened. Genetic variation of European Veratrum species was characterized by Amplified Fragment Length Polymorphism (AFLP) markers. The accumulation of jervine as a representative of steroidal alkaloids was measured in seeds. Distribution of 380 markers generated from eight primer combinations was useful for studying genetic relationships among and within species in the Veratrum genus and the most divergent populations were identified. Genetic variation between 12 populations of Veratrum species supports the classification of V. lobelianum as a subspecies of V. album. However, the results need further validation on extended material. A higher genetic diversity (22.3%) was observed between populations of V. nigrum as compared to V. album (14.5%). Contents of jervine allowed for discrimination of the studied Veratrum species and can be used as a potential chemotaxonomic marker. The highest jervine levels were found in V. album. V. nigrum seeds had only trace amounts and no jervine was detected in seeds of V. lobelianum.

Geographic Origins

Fringed brome ( Bromus ciliatus L.) is found in native stands throughout a large area of North America. Little is known about the genetic diversity of this species. The amplified fragment length polymorphism (AFLP) technique was applied to assess the genetic diversity of 16 fringed brome populations sampled in Canada from the provinces of Alberta, British Columbia, Quebec, and Saskatchewan. Four AFLP primer pairs were employed to screen 82 samples with four to six samples per population and 83 polymorphic AFLP bands scored for each sample. The frequencies of the scored bands in all assayed samples ranged from 0.01 to 0.99 and averaged 0.53. Analysis of molecular variance revealed that 52.6% of the total AFLP variation resided among the 16 populations and 20.6% among the four provinces. The five Quebec populations appeared to be genetically the most diverse and distinct. The AFLP variability observed was significantly associated with the geographic origins of the fringed brome populations. These findings are useful for sampling fringed brome germplasm from natural populations for germplasm conservation and should facilitate the development of genetically diverse regional cultivars for habitat restoration and revegetation.
