Characterization, Diagnosis & Gestion de Phytoplasmas Vol. 5
Description
Phytoplasmas are among le smallest et simplest de all known self replicating cellular organisms. These uncultivable descendents de Grampositive bacteria belong to a class de cell wall-less microorganisms known as Mollicutes. Phytoplasmas inhabit le phloem de plants et are dispersed en nature by phloem-feeding insect vectors, by vegetative propagation practices or by global transportation de infected plants. Phytoplasmas are le cause de more than a thousand incurable plant diseases worldwide among which those affecting perennial crops such as fruit trees, ornamental or forest trees, sugarcane et grapevine are de greatest economic significance. While infections are not always fatal, they are debilitating, resulting en substantial reductions en yield quality et lifespan de plants. Among le least understood de all plant pathogens, advances at le molecular level have revealed phytoplasmas are a unique, monophyletic clade de mollicutes avec minimal, albeit genetically diverse, genomes. Phytoplasma diseases are among le most significant et costly diseases affecting pome et stone fruit trees, forage, vegetable et ornamental crops en temperate regions de le world while diseases de coconut palm, papaya et sugarcane present a constant threat to production these important crops en le tropics. This book is part de le multi-volume Plante Pathogens Series. It provides 19 chapters each containing a wealth sur information sur symptomatology, economic concern, detection et management de phytoplasmas associated primarily avec fruit trees, coconut, sugarcane, forage, shade et ornamental crops.
