Use of nodulation pattern, stress tolerance, nodC gene amplification, RAPD-PCR and RFLP-16S rDNA analysis to discriminate genotypes of Rhizobium legu…

2005

Twenty-seven new Rhizobium isolates were obtained from root nodules of wild and crop legumes belonging to the genera Vicia, Lathyrus and Pisum from different agroecological areas in central and southern Italy. A polyphasic approach including phenotypic and genotypic techniques was used to study their diversity and their relationships with other biovars and species of rhizobia. Analysis of symbiotic properties and stress tolerance tests revealed that wild isolates, showed a wide spectrum of nodulation and a marked variation in stress tolerance compared with reference strains tested in this study. All rhizobial isolates (except for the isolate CG4 from Galega officinalis) were presumptively i…

On the origin and systematics of the northern African wood mouse (<i>Apodemus sylvaticus</i>) populations: a comparative study of mtDNA r…

2001

Conflicting hypotheses have been formulated regarding the origin of wood mouse (Apodemus sylvaticus) populations in northern Africa. In this study, the mtDNA restriction patterns of mice (n = 28) collected in Tunisia and Morocco are compared with those of representatives from southern Europe (n = 102). The neighbour-joining tree confirms the existence of the three lineages previously found in the Mediterranean area: western, Tyrrhenian–Balkan, and Sicilian. The western group is isolated from the two others, with bootstrap values of 89 and 95%. Northern African patterns are included in the western group. Their variability is low, the same pattern being shared by five Tunisian and all Morocca…

CURRENT ROOTSTOCK USE AND ROOTSTOCK NEEDS FOR THE FUTURE: SOUTHERN ITALY, SICILY AND ARID MEDITERRANEAN AREAS

2013

Grapevine rootstocks have been an essential component of grape growing for over 150 years as rootstocks can impart desirable characteristics for grapevine growth. This review examined Italian and Sicilian literature on rootstocks, focusing on key issues including updates on needs for the future. Other related issues include the performance of major selection traits associated with salinity, drought, potassium uptake, vegetative growth, grape and wine quality and the propagation of grafted vines. Research on rootstocks started in Italy, and of course in other European Countries, once phylloxera was imported. In Italy, phylloxera was detected in Agrate (north Italy) in August 1879, but it may…
