Article Synopsis
- Monstera deliciosa, a tropical plant popular in the U.S. for its easy care and attractive leaves, was found to have leaf lesions in Virginia due to a fungal infection.
- The symptoms included necrotic spots with reddish-brown sporulation, consistent with the fungus Pseudocerradoa paullula, which has previously been reported in the U.S. and Japan.
- Researchers extracted DNA from the spores and successfully sequenced specific gene regions, finding high genetic similarity to Florida samples in a genetic database.
Article Synopsis
- - Members of the Botryosphaeria genus are known to harm stressed oak trees in the eastern U.S., particularly affecting two similar species, Diplodia corticola and D. gallae, whose characteristics are still not fully understood.
- - On August 15, 2023, researchers collected tissue samples from a declining Quercus coccinea tree in Virginia, noting symptoms like scorched leaves and branch dieback, to analyze the specific pathogen involved.
- - The study involved isolating the pathogens, culturing them in a lab, and sequencing their DNA, resulting in the identification of DNA fragments that have been added to the GenBank database for further research.
Article Synopsis
- Since the early 1900s, oak decline has been recognized as a disease affecting hardwood forests in the U.S., with opportunistic canker pathogens causing issues like crown dieback in oak trees, particularly in mid-Atlantic states.*
-
- A survey was conducted in August 2022 in Frederick and Shenandoah Counties, Virginia, where mature Quercus montana trees showed symptoms of decline, including cankers and discolored sapwood.*
-
- Researchers collected samples from these trees, grew cultures in controlled conditions, and confirmed that the fungi from both spores and necrotic wood were morphologically identical, indicating a connection to the observed decline.*
