Insight Into the Microbial Co-occurrence and Diversity of 73 Grapevine () Crown Galls Collected Across the Northern Hemisphere.

Crown gall (CG) is a globally distributed and economically important disease of grapevine and other important crop plants. The causal agent of CG is or strains that harbor a tumor-inducing plasmid (pTi). The microbial community within the CG tumor has not been widely elucidated and it is not known if certain members of this microbial community promote or inhibit CG.

Comparative transcriptome analysis of two citrus germplasms with contrasting susceptibility to Phytophthora nicotianae provides new insights into tolerance mechanisms.

Host perception of Phytophthora nicotianae switching to necrotrophy is fundamental for disease tolerance of citrus. It involves an HR-like response, strengthening of the cell wall structure and hormonal signaling. Stem rot caused by P.

Elimination of , and from a Tunisian Cultivar by Somatic Embryogenesis and Characterization of the Somaclones Using Ampelographic Descriptors.

Prospecting of local grapevine ( L.) germplasm revealed that Tunisia possesses a rich patrimony which presents diversified organoleptic characteristics. However, viral diseases seriously affect all local grapevine cultivars which risk a complete extinction.

Composition of Citrus sinensis (L.) Osbeck cv «Maltaise demi-sanguine» juice. A comparison between organic and conventional farming.

Juices from conventionally and organically grown Citrus sinensis (L.) Osbeck cv. Maltaise demi-sanguine blood orange were investigated for quality parameters and antioxidant capacity.

Characterization of root-nodule bacteria isolated from Vicia faba and selection of plant growth promoting isolates.

A collection of 104 isolates from root-nodules of Vicia faba was submitted to 16S rRNA PCR-RFLP typing. A representative sample was further submitted to sequence analysis of 16S rRNA. Isolates were assigned to 12 genera.

Occurrence of ochratoxigenic fungi and ochratoxin A in grapes from a Tunisian vineyard.

The occurrence of ochratoxin A (OTA) and the identification of the ochratoxigenic microbiota in Tunisian grapes were studied for the first time. Black aspergilli were the dominant genus among the filamentous fungi isolated from grapes and were the only potential OTA-producing fungi found. The most abundant species were member of Aspergillus niger aggregate (63%) and Aspergillus carbonarius (36%).
