The yellow gene influences Drosophila male mating success through sex comb melanization
eLife, 2019 Drosophila melanogaster males perform a series of courtship behaviors that, when successful, result in copulation with a female. For over a century, mutations in the yellow gene, named for its effects on pigmentation, have been known to reduce male ...

Layers of immunity: Deconstructing the Drosophila effector response [PDF]
eLifeThe host innate immune response relies on the cooperation of multiple defense modules. In insects and other arthropods, which have only innate immune mechanisms, four main immune-specific modules have been described in the defense against microbial ...

Faster Cryptococcus Melanization Increases Virulence in Experimental and Human Cryptococcosis
bioRxiv, 2020 Cryptococcus spp. are important human pathogens responsible for about 180,000 deaths per year. Studying their virulence attributes can lead to better cryptococcosis prevention and treatment.

CellsParasitoid elimination in Drosophila melanogaster involves special hemocytes, called lamellocytes, which encapsulate the eggs or larvae of the parasitoid wasps. The capsules are melanized, and metabolites of the melanization reaction may play a potential

Beyond thermal melanism: association of wing melanization with fitness and flight behaviour in a butterfly [PDF]
Animal Behaviour, 2020 Cold developmental conditions can greatly affect adult life history of ectotherms in seasonal habitats. Such effects are mostly negative, but sometimes adaptive.

Fungal Genetics and Biology, 2018 We combined a common garden experimental design with digital image analysis to determine how melanization responds to temperature and fungicide stress in 126 strains of Rhynchosporium commune sampled from nine global field populations.

Bmserpin2 Is Involved in BmNPV Infection by Suppressing Melanization in Bombyx mori
Insects, 2019 Melanization, an important defense response, plays a vital role in arthropod immunity. It is mediated by serine proteases (SPs) that convert the inactive prophenoloxidase (PPO) to active phenoloxidase (PO) and is tightly regulated by serine protease ...

Melanization in response to wounding is ancestral in arthropods and conserved in albino cave species
Scientific Reports, 2017 Many species adapted to aphotic subterranean habitats have lost all body pigmentation. Yet, melanization is an important component of wound healing in arthropods. We amputated appendages in a variety of cave-adapted and surface-dwelling arthropods.
