- - In 2018 and 2019, cowpeas in Tulare County, California were found to have serious root and stem problems that affected their growth, but only a small number of plants (less than 5%) were impacted.
- - Scientists collected samples from these affected plants and discovered a harmful fungus called Fusarium solani, which can cause diseases in plants.
- - They tested how this fungus could damage cowpea plants in a greenhouse and carefully measured the results to understand how it affects their growth.
The effects of hyperbaric oxygen therapy on snake-bite-associated wounds in dogs.
J Vet Emerg Crit Care (San Antonio)
June 2024
Objective: To assess the effect of hyperbaric oxygen therapy (HBOT) on Crotalinae envenomation-induced wound swelling and severity and pain in dogs, and to describe the safety and complications of HBOT.
Design: Prospective, randomized, controlled, blinded study (2017-2021).
Setting: University teaching hospital, private veterinary practice.
Article Synopsis
- Modern taxonomic classification of fungi often relies on molecular markers, but this study employs phylogenomics to analyze 710 fungal genomes and reconstruct evolutionary relationships.
- * The research generated a new set of 1,362 high-quality molecular markers and found that about 7.59% of the fungal strains were previously misidentified, highlighting the need for better population-level sampling in species classification.
- * The findings indicate that using genomic data can significantly improve the accuracy of identifying fungal species and help resolve ongoing taxonomic debates, ultimately supporting the construction of a more precise Tree of Life.
This study was conducted to elucidate evolutionary relationships and species diversity within the species complex (FBSC). We also evaluate the potential of these species to produce mycotoxins and other bioactive secondary metabolites. Maximum likelihood and maximum parsimony analyses of sequences from portions of four marker loci (ITS rDNA, , and ) and the combined 4495 bp data set support recognition of seven genealogically exclusive species within the FBSC.
