The cereal cyst nematode, Heterodera avenae (Wollenweber, 1924) is one of the most important plant parasitic nematodes of cereals. It is an obligate sedentary endo parasite causing considerable crop losses in wheat, barley and oats worldwide. FMRFamide-like peptides (FLPs) play critical role as neurotransmitters or neuromodulators in the nervous system and proposed as one of the important targets for the plant parasitic nematode management. Therefore, for the first time we have cloned and characterized two neuropeptide genes (flp-12 and flp-16) from the cDNA library of feeding female of H. avenae. Sequence analysis of FLPs revealed that both the neuropeptides are closely related with the parasitic as well as free-living nematodes. The flp-12 contains putative 22 residue long signal peptide at N-terminal suggesting its association with extra-cellular functions, while flp-16 does not contain signal peptide. Besides this, we have found highly conserved motif KFEFIRF in flp-12 and RFGK motif in flp-16. These two flp genes could be interesting and potential targets for functional validation to explore their utility for designing management strategies.
