摘要在鼠类啮齿动物中，尿液中的挥发性化合物和主要尿蛋白（MUP）构成了塑造雄性性吸引力的关键雄性信息素。在这里，我们的目的是研究雄性信息素水平是否与褐鼠华北亚种（Rattusnorvegicus humiliatus）的性吸引力和繁殖成功有关。根据雄性尿液中主要雄性信息素2-庚酮(2H)的丰度，首先将雄性大鼠分为高2H组和低2H组。发现高 2H 组的整体挥发性谱和非挥发性 MUP 水平高于低 2H 组。此外，尿液中挥发性信息素或候选信息素的丰度与总MUP的丰度呈正相关。双向选择测试显示，高 2H 组的男性尿液比低 2H 组的男性尿液对女性更具吸引力。父系谱系的微卫星位点分析显示，雌性有单亲子关系后代，高2H组比低2H组生育更多后代，父子率更高。这些结果表明，尿液中的挥发性信息素单独或与 MUP 信息素一起可以预测雄性大鼠的性吸引力和繁殖成功率。 意义说明 性吸引力可以使用沉积尿液中的挥发性和 MUP 信息素及其候选信息来量化。 2-庚酮（一种主要信息素）和其他尿液传播的挥发性信息素或其候选物和总 MUP 在男性中表现出相同的差异模式，并预测男性的性吸引力。挥发性信息素或其候选物和总 MUP 的丰度与男性的生殖成功率和亲子率相关。
AbstractIn muroid rodents, urine-borne volatile compounds and major urinary proteins (MUPs) constitute the key male pheromones that shape the sexual attractiveness of males. Here, we aimed to examine whether male pheromone levels were related to sexual attractiveness and reproductive success in the North China subspecies of the brown rat (Rattus norvegicus humiliatus). According to the abundance of 2-heptanone (2H), the predominant male pheromone in male urine, male rats were first categorized into a high-2H group and a low-2H group. The levels of the whole volatile profile and non-volatile MUPs were found to be higher in the high-2H group than in the low-2H group. Moreover, the abundances of urinary volatile pheromones or pheromone candidates were positively correlated with the abundance of total MUPs. Two-way choice tests revealed that male urine from the high-2H group was more attractive to females than that from the low-2H group. Microsatellite loci analysis of paternal lineage revealed that the females had single-paternity offspring and that the high-2H group sired more offspring and had higher rates of paternity than did the low-2H group. These results suggest that urine-borne volatile pheromones alone or together with MUP pheromones can predict sexual attractiveness and reproductive success in male rats.Significance statementSexual attractiveness can be quantified using volatile and MUP pheromones and their candidates in deposited urine. 2-Heptanone (a major pheromone) and other urine-borne volatile pheromones or their candidates and total MUPs showed the same difference patterns in males and predicted male sexual attractiveness. The abundances of volatile pheromones or their candidates and total MUPs were associated with reproductive success and paternity rate in males.
