إنجليزي. An undescribed disease of Retama sphaerocarpa (L.) Boiss. was found in the central area of Spain in 1996. The disease was characterised by hyperplastic galls on branches, very similar to knots induced by Pseudamonas savastanoi on olive and oleander plants. The causal agent was characterised as a pathovar of Pseudomonas savastanoi. The isolated strains formed a homogeneous group of aerobic, Gram-negative, rod-shaped bacteria, which showed distinct phytopathological features when compared with other pathovars of P. savastanoi. The name P savastanoi pv. retacarpa pv. nov. is proposed for this new pathovar. The pathotype strain has been deposited in the Coleccion Espanola de Cultivos Tipo, Valencia, Spain, as CECT 4861, and in the National Collection of Plant Pathogenic Bacteria, Sand Hutton, York, U.K, as NCPPB 4050

إيطالي. [Nel 1996 e' stata trovata una malattia di Retama sphaerocarpa (L.) Boiss. non ancora descritta nell'area centrale della Spagna. La malattia era caratterizzata dalla produzione di galle iperplastiche sulle branche, molto simili ai noduli indotti da Pseudomonas savastanoi sulle piante di olivo e di oleandro. L'agente causale e' stato identificato come una patovar di Pseudomonas savastanoi. I ceppi isolati formavano un gruppo omogeneo di batteri a bastoncino, aerobici, Gram-negativi, che presentavano caratteristiche fitopatologiche distinte da quelle di altre patovar di P. savastanoi. Per questa nuova patovar viene proposto il nome di P. savastanoi pv. retacarpa pv. nov. Il ceppo del patotipo e' stato depositato presso la Coleccion Espanola de Cultivos Tipo, Valencia, Spagna, come CECT 4861, e presso la National Collection of Plant Pathogenic Bacteria, Sand Hutton, York, UK, come NCPPB 4050]
