Raffaelea lauricola (laurel wilt). [PDF]

Plant Disease, 2021
Abstract Laurel wilt is responsible for the death of hundreds of millions of redbay (Persea borbonia sensu lato) trees throughout the southeastern USA, and the disease is also having significant effects on other species such as sassafras (Sassafras albidum) in natural ecosystems and avocado (Persea americana) in commercial production areas of ...

Long-term demography and spatial genetic structure reveal mechanisms of Sassafras albidum population persistence through clonality. [PDF]

Am J Bot
Abstract Premise Vegetative regeneration is a key mechanism of woody plant persistence in forest ecosystems, and the coupled roles of basal sprouting and clonal growth in shaping long‐term population dynamics have been understudied. Basal sprouting replaces stems at fixed ramet locations, whereas clonal growth via root suckering produces spatially ...

Recommendations for Control and Mitigation of Laurel Wilt and Ambrosia Beetle Vectors in Commercial Avocado Groves in Florida

EDIS, 2020
The lethal laurel wilt epidemic affecting avocado trees in Florida is caused by a fungal pathogen-ambrosia beetle complex (LW-AB). The death of over 120,000 commercial avocado trees in Florida may be attributed to LW-AB.

First Report of Laurel Wilt Caused by Harringtonia lauricola (Previously Raffaelea lauricola) on Northern Spicebush in Kentucky and Tennessee [PDF]

Plant Disease, 2023
In the past two decades, laurel wilt disease has significantly affected members of the Lauraceae in the southeast United States, causing widespread mortality of native redbay (Persea borbonia (L.) Spreng), and incidence of infections in avocado (Persea americana Mill.), sassafras (Sassafras albidum L.) and swamp bay (Persea palustris [Raf.] Sarg ...

Molecular Detection of the Laurel Wilt Fungus, Raffaelea lauricola [PDF]

Plant Disease, 2014
The laurel wilt disease fungus, Raffaelea lauricola, is killing redbay trees, spreading rapidly in the U.S. southeastern coastal plain forest, and posing a serious threat to the avocado industry in Florida. A molecular tool is urgently required to facilitate detection of this pathogen.

Oral Fungal Alterations in Patients with COVID‐19 and Recovered Patients

Advanced Science, Volume 10, Issue 19, July 6, 2023., 2023
This research characterizes oral mycobiome in coronavirus disease 2019 (COVID‐19) patients and recovered COVID‐19 patients, constructs and validates the diagnostic model for COVID‐19, successfully diagnoses suspected cases with positive immunoglobulin G antibody as confirmed patients, and depicts the correlations between the oral microbiome and ...

Data sharing for conservation: A standardized checklist of US native tree species and threat assessments to prioritize and coordinate action

PLANTS, PEOPLE, PLANET, Volume 5, Issue 4, Page 600-616, July 2023., 2023
Understanding the current state of trees within the United States is imperative for protecting those species, their habitats, and the countless communities they support, as well as the ecosystem services they provide. We present an updated checklist of all tree species native to the contiguous United States, their state distribution, extinction risk ...
