General Information
Term melanotic mass ID (Ontology) FBbt:00005064 (Fly Anatomy)
Definition Dark melanin-containing mass that is formed at a wound site in response to injury (Markus et al., 2005; Tang, 2009; Evans et al., 2022). Its formation is mainly mediated by hemocytes (Tang, 2009).[ FlyBase:FBrf0187734 FlyBase:FBrf0215359 FlyBase:FBrf0252938 ]
Comment Melanotic masses can be caused by genetic manipulations, however this term only represents the wild-type structure produced in response to injury. Consider FBcv:0000446 for the mutant phenotype, which is sometimes also referred to as a 'melanotic tumor' or 'pseudotumor' (Minakhina and Steward, 2006 - FBrf0194475).
