Sexual reproduction is rare in these species. The primary objective of this study was to determine the genetic structure of X. pachtaicum and X. index populations using eight and seven populations, respectively, from different \u201cwine of denomination of origin (D.O.) zones\u201d in Spain and Sardinia (Italy), by studying mitochondrial (cytochrome oxidase c subunit 1 or COI) and nuclear (D2-D3 expansion segments of 28S rDNA) markers. Both Xiphinema spp. showed low intraspecific divergence among COI sequences, ranging from 0.2% (1 base substitution) to 2.3% (10 substitutions) in X. pachtaicum and from 0.2% (1 base substitution) to 0.4% (2 substitutions) in X. index. Population genetic structure was strong for both species. Nevertheless, molecular differences among grapevine-growing areas were not significant, and intrapopulation diversity was very low. It is hypothesized that this genetic homogeneity in the nematode populations reflects their predominant parthenogenetic reproduction mode and low dispersal abilities. Our results also show that X. pachtaicum populations in Spain have possibly been established from two different populations of origin. Results also demonstrated that the two DNA regions studied are suitable diagnostic markers for X. index and X. pachtaicum. <\/jats:p>","DOI":"10.1094\/phyto-07-10-0194","type":"journal-article","created":{"date-parts":[[2011,5,10]],"date-time":"2011-05-10T13:55:26Z","timestamp":1305035726000},"page":"1168-1175","source":"Crossref","is-referenced-by-count":36,"title":["Genetic Structure of <i>Xiphinema pachtaicum<\/i> and <i>X. index<\/i> Populations Based on Mitochondrial DNA Variation"],"prefix":"10.1094","volume":"101","author":[{"given":"Carlos","family":"Guti\u00e9rrez-Guti\u00e9rrez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pablo","family":"Castillo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Cantalapiedra-Navarrete","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Blanca B.","family":"Landa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sofie","family":"Derycke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan E.","family":"Palomares-Rius","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1665","reference":[{"key":"p_1","first-page":"153","volume":"72","author":"Arias M.","year":"1974","journal-title":"Bol.
