A simple floral fragrance and unusual osmophore structure in Cyclopogon elatus (Orchidaceae).
We studied gland morphology, anatomy and the chemical composition of the floral fragrance in the sweat bee-pollinated orchid Cyclopogon elatus. This is apparently the first such analysis for any Cyclopogon species, and one of very few studies in which both odour and osmophore are characterised in a nectar-rewarding orchid. Structures responsible for floral scent production were localised with n...

The karyotypes of three species of sphaerodactyl gekkonid lizards are described after conventional and differential staining. Karyotypes of Gonatodes humeralis and G. hasemani are formed by a gradual series of 32 acrocentri...

In an ongoing study human X chromosomal mental retardation genes (MRX) were mapped in the chicken genome. Up to now the homologs of 13 genes were localized by FISH techniques. Four genes from HSAXp (TM4SF2, RSK2/ RPS6KA3, N...

In higher eukaryotes, the 5S ribosomal DNA (5S rDNA) is organized in tandem arrays with repeat units composed of a coding region and a non-transcribed spacer sequence (NTS). These tandem arrays can be found on either one or...

Group B SOX genes, the closest relatives to the sex-determining gene SRY, are thought to have evolved from a single ancestral SOX B by a series of duplications and translocations. The two SOX B genes SOX2 and SOX14 co-local...
