Layered roles of fruitless isoforms in specification and function of male aggression-promoting neurons in Drosophila

eLife, 2020
Inter-male aggressive behavior is a prominent sexually dimorphic behavior. Neural circuits that underlie aggressive behavior are therefore likely under the control of sex-determining genes.

Sex-determining genes distinctly regulate courtship capability and target preference via sexually dimorphic neurons

eLife, 2020
For successful mating, a male animal must execute effective courtship behaviors toward a receptive target sex, which is female. Whether the courtship execution capability and upregulation of courtship toward females are specified through separable sex ...

Abnormal Pollen Development in the Fragaria vesca Mutant fruitless 1

HortScience, 2023
Knowledge of the genes underlying a given trait is highly useful for developing molecular markers for breeding and is the foundation for future genomic crop improvements. The cultivated strawberry, F. ×ananassa, is a valuable horticultural crop.

Fruitless decommissions regulatory elements to implement cell-type-specific neuronal masculinization.

PLoS Genetics, 2021
In the fruit fly Drosophila melanogaster, male-specific splicing and translation of the Fruitless transcription factor (FruM) alters the presence, anatomy, and/or connectivity of >60 types of central brain neurons that interconnect to generate male ...

Characterization of the Sexually Dimorphic fruitless Neurons That Regulate Copulation Duration

Frontiers in Physiology, 2018
Male courtship in Drosophila melanogaster is a sexually dimorphic innate behavior that is hardwired in the nervous system. Understanding the neural mechanism of courtship behavior requires the anatomical and functional characterization of all the neurons

Insulin Signaling in the Peripheral and Central Nervous System Regulates Female Sexual Receptivity during Starvation in Drosophila

Frontiers in Physiology, 2017
Many animals adjust their reproductive behavior according to nutritional state and food availability. Drosophila females for instance decrease their sexual receptivity following starvation.

Neuropeptide F regulates courtship in Drosophila through a male-specific neuronal circuit

eLife, 2019
Male courtship is provoked by perception of a potential mate. In addition, the likelihood and intensity of courtship are influenced by recent mating experience, which affects sexual drive.

Fruitless mutant male mosquitoes gain attraction to human odor

eLife, 2020
The Aedes aegypti mosquito shows extreme sexual dimorphism in feeding. Only females are attracted to and obtain a blood-meal from humans, which they use to stimulate egg production.

Plant Type and Antidesiccants Influence Longevity of Cut Pepper Stems for Floriculture Applications

HortTechnology, 2023
In the floriculture trade, cut pepper (Capsicum annuum) stems are typically grown for their fruit to add color contrast to the foliage and blossoms of conventional floral arrangements.

P1 interneurons promote a persistent internal state that enhances inter-male aggression in Drosophila

eLife, 2015
How brains are hardwired to produce aggressive behavior, and how aggression circuits are related to those that mediate courtship, is not well understood.
