Identification of Green-Leaf Volatiles Released from Cabbage Palms () Infected with the Lethal Bronzing Phytoplasma.

Lethal bronzing (LB) is a fatal infection that affects over 20 species of palms (Arecaceae) and is caused by the phytoplasma ' Phytoplasma aculeata'. This pathogen causes significant economic losses to landscape and nursery companies in Florida, USA. Recently, the vector was determined to be the planthopper which was more abundant on LB-infected palms.

Forest health in the Anthropocene: the emergence of a novel tree disease is associated with poplar cultivation.

Plant domestication and movement are large contributors to the success of new diseases. The introduction of new host species can result in accelerated evolutionary changes in pathogens, affecting long-established coevolutionary dynamics. This has been observed in poplars where severe epidemics of pathogens that were innocuous in their natural pathosystems occurred following host domestication.

Genetic Variability of Palm Lethal Decline Phytoplasmas in the Caribbean Basin and Florida, U.S.A., Based on a Multilocus Analysis.

Palm lethal decline phytoplasmas are an important group of plant pathogens that cause death in a variety of palm species throughout the Caribbean basin and the southeastern United States. The 16SrIV-D phytoplasma was introduced to the state of Florida, United States; it has since caused severe economic losses to the green industries of Florida and is threating natural ecosystems because of its ability to infect the native palm . In this study, the genetic variability of the 16SrIV-D phytoplasma was assessed over a 10-year period to determine if multiple introductions had occurred or if natural mutations were occurring.

High resolution mapping and candidate gene identification of downy mildew race 16 resistance in spinach.

Background: Downy mildew, the most devastating disease of spinach (Spinacia oleracea L.), is caused by the oomycete Peronospora effusa [=P. farinosa f.

Detection of Lethal Bronzing Disease in Cabbage Palms () Using a Low-Cost Electronic Nose.

Lethal Bronzing Disease (LB) is a disease of palms caused by the 16SrIV-D phytoplasma. A low-cost electronic nose (eNose) prototype was trialed for its detection. It includes an array of eight Taguchi-type (MQ) sensors (MQ135, MQ2, MQ3, MQ4, MQ5, MQ9, MQ7, and MQ8) controlled by an Arduino NANO microcontroller, using heater voltages that vary sinusoidally over a 2.

Effect of Oxytetracycline-Hydrochloride on Phytoplasma Titer and Symptom Progression of the 16SrIV-D Phytoplasma in Cabbage Palms from Florida.

Lethal bronzing (LB) is a phytoplasma disease of palms in Florida, U.S.A.

Quantification and Distribution of the 16SrIV-D Phytoplasma in the Wild Date Palm, , at Different Stages of Decline Using Quantitative PCR (qPCR) Analysis.

Lethal bronzing disease (LBD) is a fatal infection in a variety of ornamental palms in Florida caused by the 16SrIV-D phytoplasma. The disease was first found in 2006 in Florida and has since spread to 31 different counties, reaching as far north as Jacksonville and as far south as Key Largo. Stakeholders (nursery personnel, landscaping personnel, and extension agents) from across the state take and send samples for analysis.

The CpnClassiPhyR Is a Resource for 60 Universal Target-Based Classification of Phytoplasmas.

Phytoplasmas are plant-pathogenic bacteria that are associated with yield losses in many crop plants worldwide. Phytoplasma strain differentiation is accomplished using restriction fragment length polymorphism (RFLP) analysis of 16S ribosomal RNA-encoding gene sequences, which has resulted in the definition of ribosomal groups and subgroups of phytoplasmas. Due to limitations associated with this approach, a complementary classification scheme was recently developed based on RFLP analysis of the single-copy, protein-encoding gene chaperonin-60 (60).

Detection and Quantification of the 16SrIV-D Phytoplasma in Leaf Tissue of Common Ornamental Palm Species in Florida using qPCR and dPCR.

Lethal bronzing disease (LBD) is a lethal decline of various palm species caused by the 16SrIV-D phytoplasma. The disease was described in Texas in 2002 but found in Florida in 2006. Since its introduction, the phytoplasma has spread throughout much of the state.
