Molecular 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 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 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 کاملGenetic and molecular characterization of the I locus of Phaseolus vulgaris.
The I locus of the common bean, Phaseolus vulgaris, controls the development of four different phenotypes in response to inoculation with Bean common mosaic virus, Bean common mosaic necrosis virus, several other related potyviruses, and one comovirus. We have generated a high-resolution linkage map around this locus and have aligned it with a physical map constructed with BAC clones. These clo...
متن کاملCharacterization of beta tubulin DNA sequences within the Candida parapsilosis complex
Abstract Background and Purpose: Candida parapsilosis is a common cause of candidemia in children and onco-hematologic patients as well as in patients with septic arthritis, peritonitis, vaginitis, and nail and skin infections. Here, we evaluated intra- and inter-species beta tubulin DNA sequence variation within the C. parapsilosis complex with a view to establishing its utility in the identi...
