Effects of the apterous4 mutation on Drosophila melanogaster males' courtship

Journal of Neurogenetics

Abstract

The apterous4 (ap4) mutation has pleiotropic effects on the morphology and lifespan of D. melanogaster adults. The mutation also affects one aspect of male sexual behaviour. Unlike normal, sexually mature males, three day old ap4/ap4 males synthesize courtship-stimulating hydrocarbons that immature males make; as a result they elicit vigorous courtship (Jallon and Hotta, 1979; Jallon et al., 1986). Data presented in this report indicate that expression of the apterous4 mutation does not affect all aspects of sexual maturation in males. Specifically, 24-30 hour old ap4/ap4 males are capable of performing all of the courtship behaviors, including abdominal vibration, a newly described response of mutant and wild-type males to virgin females. However, the mutant males spend less time courting and are less likely to perform some of the courtship behaviours than age-matched controls. These abnormalities are probably indirect effects of the apterous4 allele's previously unreported effects on the flies' motor functions, which include partial paralysis, lack of coordination, and sluggishness.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
