Genetic diversity was investigated in 60 individuals of Primula obconica from four natural populations (from Hubei, central China, and Sichuan, south-west China) and from cultivated material. Inter-simple sequence repeat (ISSR) techniques produced 249 polymorphic bands and identified 60 ISSR genotypes. Based on Shannon's index and Nei's genetic diversity, the genetic diversity detected in all n...

Cytogenetic studies in Primulaceae are mostly available for herbaceous species, and are focused on the chromosome number determination. An accurate karyotype characterization represents a starting point to know the morphometry and class of the chromosomes. Comparison among species within Myrsine, associating these data with the nuclear 2C value, can show changes that led the karyotype evolution...

Phylogeographical studies frequently detect range shifts, both expansions (including long-distance dispersal) and contractions (including vicariance), in the studied taxa. These processes are usually inferred from the patterns and distribution of genetic variation, with the potential pitfall that different historical processes may result in similar genetic patterns. Using a combination of DNA s...
