ABOUT EFFECTS OF SOME NEUROPEPTIDES ON LOCOMOTOR BEHAVIOR OF CYST-FORMING PLANT NEMATODES

Abstract

The article presents an analysis of world literature on the study of the physiological and functional significance of FMRFamide-like neuropeptides in the neurobiology of cyst-forming plant parasitic nematodes (by the example of larvae of the 2-yearold potato cyst nematode Globodera pallida and G. rostochiensis, and soybean cyst nematode Heterodera glycines). It was shown that the basic physiological and functional characteristics of FMRFamide-like neuropeptides were obtained from the effects that have some neuropeptides on the motor activity of intact nematode larvae, and molecular studies of flp-genes that encode FMRFamidelike neuropeptides. FMRFamide-like neuropeptides belong to the largest and most diverse family of signal neuropeptides found in invertebrate animals including numerous representatives of the Nematoda type which can significantly modulate the locomotor behavioral reactions of these animals. The work discusses a physiological function of FMRFamide-like neuropeptides and the identified putative receptor of one of the neuropeptides in locomotor behavioral reactions that ensure the vital activity of cyst-forming nematodes, and the possibility of using the data in developing new targeted anthelmintics. The fact of revealing the peptidergic nervous system in cyst-forming plant nematodes, parasitic nematodes of vertebrate animals and freeliving nematodes confirms the concept about the conservation of the peptidergic nervous system in representatives of the entire Nematoda type in general.
