Ompared towards the multipoint-likelihood algorithm. The majority of maps constructed by diverse combinations of these techniques consisted of eight linkage groups corresponding towards the chromosome variety of C. vulgaris. Conclusions: All maps confirmed the independent inheritance in the most significant horticultural traits “flower type”, “flower colour”, and “leaf colour”. An AFLP marker for by far the most critical breeding target “flower type” was identified. The presented genetic map of C. vulgaris can now serve as a basis for further molecular marker selection and map-based cloning from the candidate gene encoding the unique flower architecture of C. vulgaris bud-bloomers. Search phrases: Bud-bloomer, Flower architecture, Linkage map, ML mapping, Molecular markerBackground Calluna vulgaris can be a woody landscaping plant in the Ericales order with rising financial value in Northern Europe. Here, Germany is usually a important making and exporting country. In 2010, 110 million plants of C. vulgaris have already been produced in Germany [1]. Its high popularity is due to the introduction of mutants with extended flowering time into commercial breeding. The so-called “bud-bloomers” (or “bud-flowering” phenotypes [2]) were almost certainly derived from two British clones collected in 1936 and 1948 and a number of men and women identified in natural populations in 1970 inside the Netherlands [1]. Nowadays, bud-bloomers make up the key market share of C. vulgaris in comparison with cultivars with wild-type and filled flowers because of their delayed flower senescence.

This phenotype is composed of three distinctive traits [4] and so far it has not been documented in any other plant species: the perianth remains closed during anthesis, petals are transformed into petaloid sepals, and stamens are absolutely missing (Figure 1). Since the perianth organs shield the unfertilised stigmas from cross-pollination and self-pollination is impossible as a result of lack of stamens, pollination is impeded and the flowers don’t show senescence during the flowering season till winter.Boc-NH-PEG8-CH2CH2NH2 Chemscene In spite of their commercial value, the inheritance of the most significant breeding targets “flower type”, “flower colour”, and “leaf colour” has seldom been studied or been systematically employed so far through the fairly quick breeding history of C.878167-55-6 Formula vulgaris.PMID:23991096 The bud-flowering phenotype in C. vulgaris has been identified as a monogenic recessive trait; [5] on the other hand, until now its genetic basis is unclear.?2013 Behrend et al.; licensee BioMed Central Ltd.
