Abstract :

Vitis vinifera L. is an economically important crop whose value largely depends on fruit quality, a feature that can be influenced by soil microorganisms, including arbuscular mycorrhizal fungi (AMF). AMF, able to establish symbiotic associations with vine roots, have beneficial effects on grapevine performance, including water use efficiency and replant success. Most grapevine varieties are susceptible to diseases, whose control can be performed by different approaches, including integrate pest practice (IPM). Previous reports suggested specificity in the symbiosis between grapevine and AMF and the importance of soil characteristics on this association. In the present study, we examined the AMF communities in the rhizospheric and bulk soil of V. vinifera cv. Pinot Nero, subjected to IPM, by using 454 Roche sequencing technology. The bulk and the rhizospheric soil of the grapevines were sampled before and after grape production. Genomic DNA was amplified, after extraction, according to the methods for pyrosequencing, by nested PCR using AMF specific primers of the large ribosomal subunit (LSU rDNA). Sequences were compared with both NCBI and an AMF LSU rDNA reference databases. Our data showed different AMF communities in the rhizospheric and bulk soil of V. vinifera and the importance of the sampling time in regulating AMF biodiversity. Recent Publications 1.
