- Abstract
- Root-lesion nematodes of the genus Pratylenchus are migratory endoparasites distributed
worldwide and regarded as severe constraints of economic crops. Crop damage is often
aggravated by their interactions with soilborne fungi and bacteria, resulting in complex
diseases which are biological and physiological rather than physical in nature. Morphological
identification and species delimitation of these nematodes is still problematic due to their
high morphological plasticity, the small number of diagnostic features available at species
level, the intraspecific variability of some of these characters and many incomplete
descriptions published in the literature. Thus, molecular approach, by using the ribosomal
DNA, plays a key role within the taxonomy of this genus. The ITS containing region of
eighteen species of Pratylenchus was sequenced and the variation within and between
species was assessed. Phylogenetic analyses were conducted by using different tree
reconstruction approaches: Bayesian inference (BI), neighbour-joining Log-Det (NJ),
maximum parsimony (MP) and maximum likelihood (ML). The alignment revealed small
species-specific DNA sequences suitable for the construction of potentially useful species-
specific primers or for a more promising approach for DNA barcoding of root-lesion
nematodes. (literal)
