The Xenomorphs from the Alien movie franchise were inspired by parasitoid wasps. That doesn't surprise Scott Egan, an evolutionary biologist at Rice University. He tells his students that if you can ...

A phytoplasma effector suppresses insect melanization immune response to promote pathogen persistent transmission Journal: Science Advances Published: 2025-01-31 DOI: 10.1126/sciadv.ads9781 ...

This seems to be due to confusion between the two processes of sclerotization and melanization.

Both our experiments showed that wing melanization is an important determinant of female mating success in C. p. eriphyle. However, a lack of elevational variation in male mate preference prevents ...

2. Inhibition of melanization by serpin-5 and serpin-9 promotes baculovirus infection in cotton bollworm Helicoverpa armigera - PubMed (nih.gov) 3. Identification of a Conserved Prophenoloxidase ...

We characterized the melanization response in the hemolymph of green darner dragonfly (Anax junius) nymphs. Incubation of chymotrypsin-activated hemolymph with L-DOPA resulted in volume- and ...

On the other hand, melanization is a more immediate immune response that occurs just a few minutes after infection. Melanization involves the oxidation of phenols to quinones, which then polymerize to ...

We determine that RSMV N suppresses PO-mediated melanization by interfering with the proteolytic cleavage of PPOs. Thus, RSMV N serves as the effector to attenuate hemolymph melanization and ...
