ABSTRACT
This chapter focuses on the most recent literature on PPNs with the emphasis on the use of different transgenic approaches to manage PPNs in different plant species of economic importance. Biotechnology has a role to play in incorporation of resistance against nematodes and biological control of plant nematodes. A number of genes that mediate nematode resistance have now been or soon will be cloned from a variety of plant species. Recent advancements in biotechnological approaches have made it possible to incorporate and express indigenous and heterologous proteins from one organism to another which has brought about new era in crop improvement. Genetic engineering has led to the exceptional enhancement of nematode resistance in different crop plants. Plant parasitic nematodes are highly dependent on their chemoreceptive neurons to sense distinct chemical stimuli for invasion into the plants. Nematodes use acetylcholinesterase and/or nicotinic acetylcholine receptors for proper functioning of the nervous system.
