Lycosidae females demonstrate meticulous maternal care of offspring by carrying egg sacs and juvenile spiderlings during the reproductive stage. Nuclear receptors (NRs), especially the ecdysone receptor (EcR) and ultraspiracle (USP), have attracted considerable attention in the regulation of arthropod development and reproduction due to their pivotal roles in ecdysteroid signaling cascades. In the present study, 23生殖期的狼蛛科雌蛛通过携带卵袋和幼蛛表现出细致的母性照料。在节肢动物的生长发育和生殖调控中,蜕皮激素受体EcR和超气门蛋白USP等核受体因介导蜕皮激素信号而备受关注。该研究在捕食性狼蛛——拟环纹豹蛛基因组中共鉴定到23个核受体基因,包括1个
