Spatial and Spatiotemporal Pattern Analysis of Coconut Lethal Yellowing in Mozambique [PDF]

Phytopathology®, 2010
Coconut lethal yellowing (LY) is caused by a phytoplasma and is a major threat for coconut production throughout its growing area. Incidence of LY was monitored visually on every coconut tree in six fields in Mozambique for 34 months. Disease progress curves were plotted and average monthly disease incidence was estimated.

Identification of potential insect vectors of the Cape Saint Paul Wilt Disease of coconut in Ghana by PCR

Oléagineux, Corps gras, Lipides, 2009
The vector of the phytoplasma responsible for the coconut lethal yellowing disease in West Africa is unknown to date. However, it is known that phytoplasmas are transmitted by leafhoppers and planthoppers, which are supposed to be the only ones able to ...

Phormium Yellow Leaf Phytoplasma Is Associated with Strawberry Lethal Yellows Disease in New Zealand [PDF]

Plant Disease, 1998
A yellows disease of strawberry plants was identified in propagation beds in New Zealand. Affected plants were flatter to the ground, showed purpling of older leaves, reduced leaf size, yellowing of younger leaves, and sometimes plant death. A phytoplasma was observed in the phloem of affected plants. The 16S rRNA gene of the phytoplasma was amplified

Detection and characterization of palm lethal decline phytoplasmas, subgroups 16SrIV-A and -D, in Phoenix canariensis and Syagrus romanzoffiana in Puebla, Mexico [PDF]

Journal of Plant Protection Research
Phytoplasma subgroups 16SrIV-A and -D are the agents associated with two diseases that significantly threaten palm cultivation in the Americas, namely lethal yellowing (LY) and Texas Phoenix palm decline (TPPD), respectively.

Nested PCR-Based Rapid Detection of Phytoplasma Leaf Wilt Disease of Coconut in Sri Lanka and Systemic Movement of the Pathogen

Pathogens, 2023
Phytoplasmas are associated with many plant diseases. In palms, lethal bronzing disease, Texas Phoenix palm decline, and coconut lethal yellowing decline are some of them.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Tropicsafe project: Detection and management of lethal yellowing and grapevine yellows diseases in partner countries

Phytopathogenic Mollicutes, 2021
The confirmation of the presence of 16SrXXII-B phytoplasmas associated with coconut lethal yellowing disease in Ghana and of 16SrIV in the Caribbean (Jamaica, Cuba, and Mexico) were the basis to study alternative plant species and potential insect vectors of this economically relevant disease carried out by the TROPICSAFE project started in 2017.

General overview of genetic research and experimentation on coconut varieties tolerant/resistant to Lethal Yellowing

Oléagineux, Corps gras, Lipides, 2009
The Lethal Yellowing (LY) disease is one of the main threats to coconut industry in many parts of Africa and the Caribbean. Planting resistant varieties has long been recognized as one of the most promising ways of controlling the disease.

Liquid biopsy‐based diagnostic evaluation of hypermethylated CpG sites for ovarian cancer diagnosis

Molecular Oncology, EarlyView.
This schematic outlines the workflow from biomarker identification to duplex MethyLight assay validation for epithelial ovarian cancer diagnosis using cfDNA‐based liquid biopsy. Initial screening of hypermethylated CpG candidates (cg02957270, cg10061138 cg00480298, COL2A1) was performed in tissue using ARMS‐PCR, COBRA, qPCR and image analysis. Selected

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

FEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.
