The terrestrial isopod, Armadillidium vulgare is usually grey or black in color, however, red ones are occasionally found in the field. This is caused by the mutation of the ommochrome genesis in the integument. We focused our experiments on the mechanism of pigment genesis in which tryptophan metabolism had been expected to be different from the grey or black wild types. We obtained the result that 3-hydroxyanthranilic acid content was significantly higher in the red phenotype than in the wild type, and kynureninase activity was also higher in the red phenotype.
陆生等足类动物鼠妇通常为灰色或黑色，但偶尔也能在野外发现红色的个体。这是由体表眼色素生成的突变引起的。我们将实验重点放在色素生成机制上，预计其中色氨酸代谢与灰色或黑色野生型不同。我们得到的结果是，红色表型中3-羟基邻氨基苯甲酸的含量显著高于野生型，且红色表型中的犬尿氨酸酶活性也更高。
