Molecular detection and characterization of phytoplasmas associated with lethal yellowing disease of coconut palms in Jamaica
Tissue samples were collected from coconut palms with symptoms of lethal yellowing (LY) disease in Jamaica. Palms were sampled at 50 sites exhibiting varying levels of mortality due to LY. Samples were assayed for phytoplasma infection by polymerase chain reaction (PCR) assays. Detected phytoplasmas were characterized by dot blot nucleic acid hybridisation, restriction fragment length polymorph...
متن کاملCoconut Lethal Yellowing Diseases: A Phytoplasma Threat to Palms of Global Economic and Social Significance
The recent discovery of Bogia coconut syndrome in Papua New Guinea (PNG) is the first report of a lethal yellowing disease (LYD) in Oceania. Numerous outbreaks of LYDs of coconut have been recorded in the Caribbean and Africa since the late Nineteenth century and have caused the death of millions of palms across several continents during the Twentieth century. Despite the severity of economic l...
متن کاملBiochemical profile of coconut water from coconut palms planted in an inland region.
OBJECTIVE To analyze the biochemical profile of coconut water from dwarf coconut palms planted in non-coastal regions, during the maturation period (sixth to ninth month). METHODS Eight of 15 coconut palms planted in a non-coastal region were selected by lots and their coconuts sent to a laboratory for extraction and analysis of the coconut water. Coconut water from a total of 45 coconuts, fr...
متن کاملEffect of Various Antibiotics on Development of Lethal Yellowing in Coconut Palm
Fifty coconut palms exhibiting early symptoms of lethal yellowing were selected for treatment with oxytetracycline-HCl, tetracyclineHC1, streptomycin nitrate, potassium penicillin-G, or griseofulyin. Two grams of antibiotic in 0.2 or 1.0 liters of water were pressure injected into the trunk of each tree except for the griseofulvin treatments which were applied as a paste into holes bored in the...
