چکیده
Zephyranthes citrina is an ornamental American bulbous plant used as garden crop for the aesthetic qualities of its yellow perigonium. The objective this work was to characterize species by classical chromosome staining and fluorochrome banding. A sporophytic number 2n=8x=48 chromosomes observed, being karyotypic formula 20 m + 26 sm 2 st. Satellites were detected in short arm metacentric 8, 9, 11 12, which colocalized with constitutive heterochromatin CMA+/DAPI-/0 bands. karyotype comprised pairs terminal bands that included satellites heteromorphic clusters indicating it allooctoploid. These results will be a tool monitoring genetic improvement, interspecific crosses progenies biotechnological procedures vitro culture. Key words: heterochromatin, banding, bulbous, resources,

متن کاملSHEsisPlus, a toolset for genetic studies on polyploid species.
Currently, algorithms and softwares for genetic analysis of diploid organisms with bi-allelic markers are well-established, while those for polyploids are limited. Here, we present SHEsisPlus, the online algorithm toolset for both dichotomous and quantitative trait genetic analysis on polyploid species (compatible with haploids and diploids, too). SHEsisPlus is also optimized for handling multi...
