A single mutation alters production and discrimination of Drosophila sex pheromones

A mutation with major effects on Drosophila melanogaster sex pheromones.

Sex pheromones are intraspecific chemical signals that are crucial for mate attraction and discrimination. In Drosophila melanogaster, the predominant hydrocarbons on the cuticle of mature female and male flies are radically different and tend to stimulate or inhibit male courtship, respectively. This sexual difference depends largely upon the number of double bonds (one in males and two in fem...

Sex and the single neuron: pheromones excite.

Pheromones are potent chemical signals used by animals across all phyla to control reproductive function and social behavior. Whereas there are few examples of the effects of pheromones on human behavior (fortunately?), in other species, such as laboratory mice, the effects of pheromones have been shown to be dramatic: a female mouse might abort a pregnancy if exposed to pheromones from a male ...

1 A mutation with major effects on Drosophila melanogaster sex pheromones

The joy of sex pheromones.

Sex pheromones provide an important means of communication to unite individuals for successful reproduction. Although sex pheromones are highly diverse across animals, these signals fulfil common fundamental roles in enabling identification of a mating partner of the opposite sex, the appropriate species and of optimal fecundity. In this review, we synthesize both classic and recent investigati...

Detection and Discrimination of Theileria annulata and Theileria lestoquardi by using a Single PCR

  The aim of this study was to detect and differentiate Theileria annulata and T. lestoquardi (hirci) by PCR. Members of the genus Theileria are tick-borne hemoprotozoan parasites those cause fatal and enervating diseases of cattle and sheep in Iran . In order to develop a specific method for detecting and identification of Theileria species, specific primers from the surface protein (SP) seque...
