Characterization of acetylcholinesterase molecular forms of the root-knot nematode, Meloidogyne
1991
Chang, S. | Opperman, C.H.
Multiple molecular forms of acetylcholinesterase have been isolated and characterized from the root-knot nematodes Meloidogyne arenaria and Meloidogyne incognita. The forms of enzyme present in these 2 species are similar but not identical to those that occur in the free-living nematode Caenorhabditis elegans. The 5 enzyme forms exhibit differential solubilities and can be classified into 3 classes. A, B, and C, based on substrate affinity, inhibitor and detergent sensitivity, and thermal inactivation profiles. An unusual class of acetylcholinesterase has been isolated from Meloidogyne which has very high affinity for acetylcholine, but is highly resistant to carbamate and organophosphate inhibitors. The potential roles of the molecular forms in nematode behavior and sensitivity to nematicides are discussed.
