A short insert genomic library for Xiphinema index, the natural vector of Grapevine Fanleaf Virus, was constructed from degenerate oligonucleotide primed PCR (DOP-PCR) products. The genomic library was screened for (CA)n microsatellites. Screening of 6200 colonies and comparison of sequencing results revealed seven (CA)n containing microsatellites, coded here as XIMSL1, XIMSL2, XIMSL3, XIMSL4, XIMSL5, XIMSL6, XIMSS1. XIMSL prefixed microsatellites were followed by the motif of the same long interspersed element. Microsatellite XMSS1 has some similarity to the shorst interspersed element. Except for XIMSL1, all microsatellites were proven to be effective diagnostic tools at species level. genetic diversity between and within populations was also evaluated for each microsatellite.

Abstract
A short insert genomic library for Xiphinema index, the natural vector of Grapevine Fanleaf Virus, was constructed from degenerate oligonucleotide primed PCR (DOP-PCR) products. The genomic library was screened for (CA)n microsatellites. Screening of 6200 colonies and comparison of sequencing results revealed seven (CA)n containing microsatellites, coded here as XIMSL1, XIMSL2, XIMSL3, XIMSL4, XIMSL5, XIMSL6, XIMSS1. XIMSL prefixed microsatellites were followed by the motif of the same long interspersed element. Microsatellite XMSS1 has some similarity to the shorst interspersed element. Except for XIMSL1, all microsatellites were proven to be effective diagnostic tools at species level. genetic diversity between and within populations was also evaluated for each microsatellite.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
