Single gene is genetic switch for fly sexual behavior

A new study found that a single gene, Fruitless, is responsible for controlling fly sexual behavior. The researchers discovered that female flies with the male version of the protein behave like males and engage in nearly identical courtship rituals.

What women want makes a difference

Researchers identified two new loci influencing female mate choice, favoring same-species mating over closely related ones. Genetic analysis shows female mating discrimination is inherited as a dominant trait, with genes linked to olfaction and X chromosomes.

Nitric oxide is essential for animal development

Researchers discover nitric oxide synthase is crucial for Drosophila development, leading to the death of flies lacking the gene. The study uses genetic analysis and mutations to provide conclusive evidence that NOS function is essential for an organism's development.

Can an old gene learn new tricks?

Researchers discovered that the Hmx gene, which was previously thought to only develop the central nervous system in fruit flies, can also direct development of the inner ear and hypothalamus in mice. This suggests that old genes can be repurposed for new functions through regulatory element shuffling, enabling evolutionary advancements.

A gene that keeps species apart

Biologists discover a candidate hybrid compatibility gene that exhibits functional divergence, confirming its status as a true speciation gene. The findings provide new insights into the molecular mechanisms of reproductive isolation, which is crucial for defining species.

When 'reaper' gene comes, cell death follows

In a groundbreaking study, researchers identified the 'reaper' genes as critical components of cell death in Drosophila. The discovery opens doors to developing targeted cancer treatments by unleashing death-inducing genes specifically at unwanted cells. Ecdysone plays a crucial role in triggering this process.

Geneticists show ripple effects of gene mutations

Researchers at North Carolina State University found that changes to genes regulating olfactory behavior in fruit flies have far-reaching implications. The study used a model organism to quantify the extent of ripples in the genome affecting behavior, revealing that two-thirds of affected genes impact olfactory behavior.

Gene helps regulate longevity in flies, and perhaps humans

A recent study by North Carolina State University researchers found that a gene variant in the Dopa decarboxylase enzyme is associated with variation in fruit fly lifespan. The study's results suggest that this genetic variation may also play a role in human longevity, with potential implications for pharmacological interventions to im...

Lone gene could force re-think on pest insect control

Researchers have discovered a single gene mutation in flies that provides resistance to multiple, chemically unrelated pesticides. This mutation has spread globally and has been linked to devastating consequences if not addressed through reassessment of current pest management methods.

What goes wrong in older eggs?

Researchers used fruit flies to study how age affects meiosis, a specialized cell division that gives rise to eggs and sperm. The study found that as fruit fly eggs 'age', errors in cell division increase, mirroring the phenomenon in humans, where birth defects like Down syndrome rise with maternal age.

Fly mutation suggests link to human brain disease
