Amino acid profile and its biochemical path in phytonematodes of high altitude environment

A study was conducted to determine the amino acid profile and its biochemical path in some plant parasitic nematodes viz. Hoplolairnus indicus, Helicotylenchus indicus and Tylenchorhynchus brevilineatus at different altitudes (at 450,650 and 1900m Above Sea Level) in Garhwal Himalayan soils. A total of 19 amino acids (6-essential; 6-semi-essential and 7-non-essential) were detected from all the studied nematodes. The common amino acids were detected as-alanine, aspartic acid, cysteine, cystine, glutamic acid, glycine, histidine, hydroxyproline, isoleucine, leucine, ornithine, phenyl-alamine, proline, serine, threonine and tyrosine. Isoleucine was detected in Hoplolairnus indicus and Helicotylenchus indicus at higher altitude (650m and 1900m ASL). Amino butyric acid and 3, 4- dihydroxyphenylalanine were detected in Helicotylenchus indicus at the same altitude. Threonine was unusual amino acid detected in Hoplolairnus indicus and T. bravilineatus only at 450±50m ASL glutamic acid and ornithine were detected only at 1900±100m ASL.
