Pardosa pseudoannulata mother adopts a compensatory strategy for reproduction deficiency resulting from the suppression of EcR/USP-1-mediated ecdysteroid signaling
Abstract:Spiders express specific maternal care to their offsprings. The predatory spider Pardosa pseudoannulata mother constructs an eggsac to protect her eggs and juvenile spiderlings. However, here we found that the female spiders ate their eggsacs when ecdysteroid signaling was suppressed. Nuclear receptors (NRs), especially ecdysone receptor (EcR) and ultraspiracle (USP), have attracted extensive attention in arthropods because of their pivotal roles in ecdysteroid signaling cascades. An EcR and two USPs were iden… Show more
