MELANISM AND HUMIDITY [PDF]

The Canadian Entomologist, 1891
At different times considerable attention has been paid to the general darkening in colour of our British insects, compared with Centrall European and with American forms. In Britian, many species become much darker(some absolutely black) on various parts of the West Coasts of Ireland and Great Britian, and, as a general rule, the more humid districts ...

Identification of a Conserved Prophenoloxidase Activation Pathway in Cotton Bollworm Helicoverpa armigera

Frontiers in Immunology, 2020
Melanization is a prominent insect humoral response for encapsulation of and killing invading pathogens. It is mediated by a protease cascade composed of a modular serine protease (SP), and clip domain SPs (cSPs), which converts prophenoloxidase (PPO ...

LAC2 Encoding a Secreted Laccase Is Involved in Appressorial Melanization and Conidial Pigmentation in Colletotrichum orbiculare

Molecular Plant-Microbe Interactions, 2012
Both Colletotrichum and Magnaporthe spp. develop appressoria pigmented with melanin, which is essential for fungal pathogenicity. 1,8-Dihydroxynaphthalene (1,8-DHN) is believed to be polymerized to yield melanin around the appresorial cell wall through ...

Faster cryptococcus melanization increases virulence in experimental and human cryptococcosis [PDF]

, 2022
Cryptococcus spp. are human pathogens that cause 181,000 deaths per year. In this work, we systematically investigated the virulence attributes of Cryptococcus spp.

Molecular identification and enzymatic properties of laccase2 from the diamondback moth Plutella xylostella (Lepidoptera: Plutellidae)

Journal of Integrative Agriculture, 2018
Laccase (EC 1.10.3.2) is known to oxidize various aromatic and nonaromatic compounds via a radical-catalyzed reaction, which generally includes two types of laccase, Lac1 and Lac2.

Melanization and Tyrosinase Activity

Journal of Investigative Dermatology, 1971
Purified soluble tyrosinase isolated from the melanosomes of Harding-Passey mouse melanoma was incubated with L-dopa. The reaction velocity of the tyrosinase thus incubated decreased significantly. There was an inverse linear relationship between the concentration of dopa in the preincubation mixture and the reaction velocity of the tyrosinase which ...

A phytoplasma effector suppresses insect melanization immune response to promote pathogen persistent transmission

Science Advances
Insect melanization triggered by the conversion of prophenoloxidase to active phenoloxidase via serine proteases (SPs) is an important immediate immune response.
