We have investigated the phenotypic effects of a mutant allele that results in the expression of a phosphoglucomutase locus (Pgm1) in the liver of rainbow trout. Embryos with liver Pgm1 expression hatch earlier than embryos without liver Pgm1 expression. These differences apparently result from increased flux through glycolysis in embryos with liver PGM1 activity while they are dependent on the yolk for energy. Fish with liver PGM1 activity are also more developmentally buffered, as indicated… CONTINUE READING
