E. auteur aut IRD text journalArticle eng text/pdf born digital access Low density of an unknown root-knot nematode was found on wild olive soils at Cape Spartel near Tanger city in northern Morocco. Morphometry, esterase and malate dehydrogenase electrophoretic phenotypes, as well as ribosomal DNA (rDNA) and mitochondrial DNA (mtDNA) sequences demonstrated that this nematode species differs clearly from other previously described root-knot nematodes. The species is herein described, illustrated and named as Meloidogyne spartelensis n. sp. This new root-knot nematode can be morphologically distinguished from other Meloidogyne spp. by: (i) roundish perineal pattern, dorsal arch low, with fine, sinuous cuticle striae, lateral field faintly visible; (ii) female excretory pore posterior to stylet knobs, EP/ST ratio 1.4-2.0; (iii) second-stage juveniles with hemizonid located 1 to 2 annuli anterior to excretory pore and long, sub-digitate tail; and (iv) males with lateral field composed of four incisures, with areolated outer bands. Phylogenetic trees based on 18S, ITS1-5.8S-ITS2, D2-D3 of 28S rDNA, and partial coxII-16S rRNA and coxI gene of mtDNA showed that M. spartelensis n. sp. belongs to an undescribed root-knot nematode lineage that is clearly separated from other species with resemblance in morphology, such as M. dunensis, M. kralli, and M. sewelli. specialized 18S Bayesian inference Cytochrome oxidase subunit II ITS Maximumlikelihood mtDNA New species Plant-parasitic nematodes rDNA MAROC 076 074 143 1 25-42 2015 0929-1873 https://www.documentation.ird.fr/hor/fdi:010064896 10.1007/s10658-015-0662-3 0929-1873 [F B010064896] https://www.documentation.ird.fr/hor/fdi:010064896 https://www.documentation.ird.fr/intranet/publi/2015/09/010064896.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-10-07 2017-08-23 fdi:010064896 fre
