DIFFERENTIAL SUSCEPTIBILITY OF OLIVE VARIETIES TO OLIVE KNOT DISEASE IN ISTRIA

Selection of olive varieties for tolerance to iron chlorosis.

Under certain conditions, olive trees grown on calcareous soils suffer from iron chlorosis. In the present study several olive varieties and scion-rootstock combinations were evaluated for their tolerance to iron chlorosis. Plants were grown over several months in pots with a calcareous soil, under two fertilization treatments. These consisted of periodic applications of nutrient solutions cont...

Differential Protein Expression in Olive Tissues Due to Salt Treatments

In this work, differential protein expression in olive tissues after salt treatments has been investigated. Olive clones selected in vitro according to their salt tolerance were submitted, also in vitro, to high salt concentrations. After each treatment, the leaves and stems were collected and protein extracts of them subjected to polyacrilamide gel electrophoresis to analyse their band pattern...

The olive knot disease as a model to study the role of interspecies bacterial communities in plant disease

There is an increasing interest in studying interspecies bacterial interactions in diseases of animals and plants as it is believed that the great majority of bacteria found in nature live in complex communities. Plant pathologists have thus far mainly focused on studies involving single species or on their interactions with antagonistic competitors. A bacterial disease used as model to study m...

Reduction of olive knot disease by a bacteriocin from Pseudomonas syringae pv. ciccaronei.

A bacteriocin produced by Pseudomonas syringae pv. ciccaronei, used at different purification levels and concentrations in culture and in planta, inhibited the multiplication of P. syringae subsp. savastanoi, the causal agent of olive knot disease, and affected the epiphytic survival of the pathogen on the leaves and twigs of treated olive plants. Treatments with bacteriocin from P. syringae pv...
