Dealing with Lethal Yellowing and Related Diseases in Coconut

2020
The coconut is a palm of economic and social importance; it is cultivated in 90 countries around the world and the markets of some of its products have been growing exponentially, representing a very promising future for the coconut cultivation and industry.

Susceptibility of Coconut Palm to Lethal Yellowing Disease

Nature, 1966
COCONUT palms (Cocos nucifera) are not susceptible to lethal yellowing disease1 until they are from two to three years old, reckoning from the time they are planted out from the nursery bed. Rare instances are known where palms have become infected at 18 months.

Molecular and biological characterization of phytoplasmas from coconut palms affected by the lethal yellowing disease in Africa

Microbiological Research, 2019
Côte d'Ivoire lethal yellowing (CILY) is a devastating disease associated with phytoplasmas and has recently rapidly spread to several coconut-growing areas in the Country. Phytoplasmas are phloem-restricted bacteria that affect plant species worldwide.

Genetic diversity in the coconut lethal yellowing disease phytoplasmas of East Africa [PDF]

Plant Pathology, 1999
DNA primers, based on the ribosomal sequences of lethal yellowing‐type disease (LYD) phytoplasmas, were used to analyse genetic variation within the lethal yellowing‐type diseases of coconut in East Africa. Samples were collected from palms in Kenya, Mozambique and high, medium and low disease incidence areas of Tanzania.

Phytoplasma distribution in coconut palms affected by lethal yellowing disease

Annals of Applied Biology, 2011
Lethal yellowing (LY), the most devastating disease affecting the coconut palm in America, is caused by phytoplasmas known to be distributed in different parts of infected plants. However, no comprehensive reports exist on the phytoplasma distribution.

One year of survey for lethal yellowing disease of palms in Guadeloupe, France

2022
Lethal yellowing (LY) disease of palms is associated with phytoplasmas of the 16SrIV group in the Caribbean. In Guadeloupe, 'Candidatus Phytoplasma palmae' (16SrIV-A subgroup) was reported in 2021. Coconut and palm trees are used for home consumption by Guadeloupeans, for the production of 'coco water' and desserts.

The genetics of durable resistance to lethal yellowing disease

1995
In 1984, the Food and Agriculture Organisation of the United Nations (FAO) held a meeting “to review the ‘State of the Art’ of disease resistance breeding in tropical perennial crops”. Subsequently published as “Breeding for durable resistance in perennial crops”, the proceedings dealt with banana, cacao, coffee, oil palm, rubber and sugar cane, but ...

Environmental Impact of Lethal Yellowing Disease of Coconut Palms

Environmental Conservation, 1975
Lethal Yellowing disease has been devastating Coconut, and presumably 14 other species of palms (including Palmyra and Date Palms), in mainland Florida since 1971. The urban environment has changed rapidly with the death of palm trees along streets, parks, and beaches.

Detection and diagnosis of African lethal yellowing-like diseases

1999
Coconut lethal decline diseases, caused by phytoplasmas, are the most important threat to world coconut palm (Cocos nucifera L.) production (Harries, 1978). These diseases are endemic in several countries of the western Caribbean and Central America, where they are collectively known as lethal yellowing (LY) diseases (Howard and Barrant, 1989; Harrison

Strawberry lethal yellows and green petal diseases in Australia

2005
In Australia the strawberry diseases, lethal yellows and green petal, are associated with Candidatus Phytoplasma australiense (Ca. P. australiense). In addition, a rickettsia-like-organism (RLO) is associated with Australian strawberry lethal yellows (SLY) disease. Ca. P.
