The phylogenetic relationships among phy toplasmas were generally in agreement with those obtained on the basis of the 16S rRNA gene in the present and previous works, however, the rp gene-based phylogeny allowed for finer resolution of distinct lineages within the phytoplasma 16Sr groups.
Transmission of European stone fruit yellows phytoplasma by Cacopsylla pruni.
Interestingly, pear decline and European stone fruit yellows, members of the apple proliferation cluster, are both transmitted by Cacopsylla spp.
Transmission Characteristics of the European Stone Fruit Yellows Phytoplasma and its Vector Cacopsylla Pruni
Under natural conditions retention of infectivity in C. pruni lasts through the winter and the following spring, when the overwintering insects reach the stone fruit trees, they are already infected and infective.
TRANSMISSION OF PEAR DECLINE BY USING NATURALLY INFECTED CACOPSYLLA PYRI L.
THE RECOVERY PHENOMENON IN APPLE PROLIFERATION-INFECTED APPLE TREES
It was demonstrated that recovered plants maintain infectivity in their roots while they lose phytoplasmas from shoots and leaves; in contrast, apple proliferation symptomatic trees are completely colonised.
MOLECULAR DIFFERENTIATION OF 'CANDIDATUS PHYTOPLASMA MALI' AND ITS SPREADING IN FRIULI VENEZIA GIULIA REGION (NORTH-EAST ITALY)
TRANSMISSION OF EUROPEAN STONE FRUIT YELLOWS PHYTOPLASMA TO PRUNUS SPECIES BY USING VECTOR AND GRAFT TRANSMISSION
Symptom Expression and Disease Occurrence of a Yellows Disease of Grapevine in Northeastern Italy
A severe yellows type disease of grapevine (GYD) has been detected in various regions of Italy since 1982. One of the most susceptible cultivars is Chardonnay. Symptoms of GYD are indistinguishable…
THE 'LIFE CYCLE' OF PEAR DECLINE PHYTOPLASMA IN THE VECTOR CACOPSYLLA PYRI
Control of the overwintering adults of C. pyri appears to be of fundamental importance for preventing the spread of pear decline.
A real-time PCR method for detection and quantification of 'Candidatus Phytoplasma prunorum' in its natural hosts
A real-time PCR assay conjugated with the fluorescent SYBR ® Green I dye has been developed for rapid, sensitive and quantitative detection of ‘Candidatus Phytoplasma prunorum’ in its natural hosts,…
