Plasticity for colour adaptation in vertebrates explained by the evolution of the genes pomc, pmch and pmchl	2019-03-10		.txt	text/plain	9270	487	52	We suggest an explanation for the differences in the mechanisms that evolved to regulate background adaptation by inferring ancestral relationships, and assessing associations with plastic colour change, the ability of α-MSH, MCH and MCHL peptides to be synthesized and secreted and to work as neuroendocrine hormones, as well as their effects on skin pigmentation. Interestingly, several species in this group lack the dual-hormonal mechanism, in that MCH/MCHL plasma levels but not α-MSH vary with background adaptation, including flounders (Verasper moseri and Platichthys flesus) (Gilham & Baker, 1984; Kang & Kim, 2013; Mizusawa et al., 2011) and tilapias from the genus Oreochromis (Nile and Mozambique) (Gröneveld, Balm, Martens et al., 1995a; Gröneveld, Balm, & Wendelaar Bonga, 1995b; van der Salm, Metz, Wendelaar Bonga, & Flik, 2005) . We used both the structure and presence of pomc, pmch and pmchl as a "genetic basis," alongside MCH/MCHL "hormonal status," to explain differences in the physiological mechanisms for background adaptation over evolution.	./cache/cord-009969-ln91qfg4.txt	./txt/cord-009969-ln91qfg4.txt
