Analysis of the Sinningia speciosa Diversity under Domestication

Sinningia speciosa (commonly known as Florist’s gloxinia) is herbaceous perennial species endemic to the Atlantic coastal forest of southeastern Brazil. This species has been known as ornamental plant since the 19^th century in England. John Fyfe developed the first hybrid in 1845 and since then, the intense breeding has produced a wide range of different phenotypes, mainly affecting the leaf color, the flower morphology and corolla color. S. speciosa genome size ranging from 321 Mb to 447 Mb. We present here the first draft of a genome sequence based on the accession ‘Avenida Niemeyer’ with a total assembly size of 373 Mb and 31,600 gene models. The genetic analysis of 36 wild and cultivated accessions revealed an expected genetic bottleneck related with single population as possible source of domestication.
