Apple Proliferation Phytoplasma Influences the Pattern of Plant Volatiles Emitted Depending on Pathogen Virulence
Apple proliferation (AP) and pear decline (PD) are the most severe diseases in pome fruit growing areas. AP-infected trees show typical symptoms such as witches’ broom, enlarged stipules, tasteless, and dwarf fruits. PD-infected pears show a progressive weakening, reduced terminal growth, smaller fruits, and die within weeks (quick decline) or years (slow decline). The diseases are caused by th...
متن کاملApple Proliferation Phytoplasma
Introduetion Apple proliferation (AP) is one of the most economically important phytoplasmal diseases in Europe. It seriously impairs fruit size, yield, and vigor of the trees. AP was first reported in northern Italy (Rui et al., 1950). In the following decades, the occurrence of AP was reported from most European countries. Due to its transmissibility by grafting, the disease was initially tho...
متن کاملPhysical map of the chromosome of the apple proliferation phytoplasma.
A physical map of the apple proliferation phytoplasma strain AT chromosome was constructed from genomic DNA extracted from diseased tobacco plants. The map was generated with single and double digestions of the chromosome with BssHII, SmaI, MluI, and ApaI restriction endonucleases and resolving the fragments by pulsed-field gel electrophoresis. Partial digestion and Southern blot analysis were ...
متن کاملUpdate on Biochemistry of Plant Volatiles Biochemistry of Plant Volatiles
Plants have a penchant for perfuming the atmosphere around them. Since antiquity it has been known that both floral and vegetative parts of many species emit substances with distinctive smells. The discovery of the gaseous hormone ethylene 70 years ago brought the realization that at least some of the compounds emitted may have physiological significance without any distinctive smell to humans....
متن کامل'Candidatus Phytoplasma mali', 'Candidatus Phytoplasma pyri' and 'Candidatus Phytoplasma prunorum', the causal agents of apple proliferation, pear decline and European stone fruit yellows, respectively.
Apple proliferation (AP), pear decline (PD) and European stone fruit yellows (ESFY) are among the most economically important plant diseases that are caused by phytoplasmas. Phylogenetic analyses revealed that the 16S rDNA sequences of strains of each of these pathogens were identical or nearly identical. Differences between the three phytoplasmas ranged from 1.0 to 1.5% of nucleotide positions...
