Occurrence of dopamine in Panagrellus redivivus and Meloidogyne incognita
Nematology 3 (8), 843-848
Abstract: Dopamine-like immunoreactivity was detected in various parts of the nervous system of adult males and females of the free-living nematode Panagrellus redivivus, including the nerve ring and some cephalic processes, the ventral nerve cord, and the tail region. Positive immunoreactivity for dopamine was not found in infective second stage juveniles (J2) of the root-knot nematode Meloidogyne incognita. This putative neurotransmitter was detected by HPLC in homogenates of both species, the dopamine content in P. redivivus being eight times greater than in M. incognita. No other catecholamine compounds were detected in these species by HPLC. The development of a more sensitive immunocytochemical assay for dopamine will be required to determine the location of dopamine in the nervous system of M. incognita J2.
