Genetic Variation in Natural and Cultivated Populations of Primula Veris
Primula veris, a well-known pharmaceutical plant, is a long-lived perennial protected by law in Poland, so its rhizomes and roots can be collected as pharmaceutical stock only from cultivation. Genetic variation of three natural P. veris populations numbering 500–1200 individuals and of three cultivated populations derived from seeds collected from natural sites was investigated in respect of t...
متن کاملFloral heteromorphy in Primula vulgaris: progress towards isolation and characterization of the S locus.
BACKGROUND The common primrose, Primula vulgaris, along with many other species of the Primulaceae, exhibits floral heteromorphy in which different individuals develop one of two possible forms of flower, known as pin and thrum. Both flower types are hermaphrodite and exhibit reciprocal positions of male and female reproductive structures, which together with a sporophytic incompatibility syste...
متن کاملMolecular characterization of DNA sequences from the Primula vulgaris S-locus.
Primula species provide possibly the best known examples of heteromorphic flower development and this breeding system has attracted considerable attention, including that of Charles Darwin. However, despite considerable recent advances in molecular genetics, nothing is known about the molecular basis of floral heteromorphy. The first molecular marker for the Primula S-locus is reported here. Th...
متن کاملOakleaf: an S locus‐linked mutation of Primula vulgaris that affects leaf and flower development
In Primula vulgaris outcrossing is promoted through reciprocal herkogamy with insect-mediated cross-pollination between pin and thrum form flowers. Development of heteromorphic flowers is coordinated by genes at the S locus. To underpin construction of a genetic map facilitating isolation of these S locus genes, we have characterised Oakleaf, a novel S locus-linked mutant phenotype. We combine ...
متن کاملPrimula Culture and Production
The name Primula or primrose is derived from the word primary or first, referring to the early growth and flowering in spring (Liberty Hyde Bailey Hortorium, 1976). More than 400 species of primula exist in the family Primulaceae (Griffiths, 1994). Other important horticultural genera in this family, besides primula, include pimpernel (Anagallis), rock jasmine (Androsace), persian violet, alpin...
