Effect of CrylAb protein on hemocytes of the wolf spider Par do sa pseudoannulata.

Studies on the effect of CrylAb protein on hemocytes of the wolf spider Pardosa pseudoannulata revealed that CrylAb protein could accumulate in the four-instar and adult spiders via the food chain from transgenic rice expressing CrylAb protein through its prey brown planthoppers with approximate 20-time enrichment, but could not accumulate in hemolymph of the spider. The accumulated CrylAb had no significant effects on several elements of hemolymph including stored energy, calcium ion concentration and apoptosis rate of the hemocytes, indicating that CrylAb could not affect the hemocytes of P. pseudoannulata.
