We identified the causal genetic variation for the difference in the thoracic trident pigmentation intensity between two wild-derived strains of Drosophila melanogaster. It was found to be the difference in expression level of ebony, which codes for an enzyme in the melanin-synthesis pathway and has pleiotropic effects on vision and behavior.
我们确定了黑腹果蝇两个野生品系之间胸部三叉色素沉着强度差异的因果遗传变异。结果发现,这是由ebony基因表达水平差异导致的,ebony基因编码黑色素合成途径中的一种酶,并且对视觉和行为具有多效性影响。
