Following air sampling fungal DNA needs to be extracted and purified to a state suitable for laboratory use. Our laboratory has developed a simple method of extraction and purification of fungal DNA appropriate for enzymatic manipulation and Polymerase Chain Reaction (PCR) applications. The methodology described is both rapid and cost effective for use with multiple fungal organisms.

Background: Accurate identification of Fusarium species requires molecular identification. Treating fusariosis is challenging due to widespread antifungal resistance, high rates of treatment failure, and insufficient information relating antifungal susceptibility to the clinical outcome. Despite recent outbreaks in Mexico, there is limited information on epidemiology and antifungal susceptibility testing (AST).

Background: Biological control methods involving entomopathogenic fungi like Beauveria bassiana have been shown to be a valuable approach in integrated pest management as an environmentally friendly alternative to control pests and pathogens. Identifying genetic determinants of pathogenicity in B. bassiana is instrumental for enhancing its virulence against insects like the resistant soybean pest Piezodorus guildinii.

Ochratoxin A (OTA) is a mycotoxin, a common contaminant of grapes and their derivatives, such as wine, and classified as possible human carcinogen (group 2B) by the International Agency for Research on Cancer (IARC). is the main producer of OTA in grapes. The stability of the molecule and the poor availability of detoxification systems makes the control of in vineyards the main strategy used to reduce OTA contamination risk.

Polygonatum cyrtonema Hua (Duohua Huangjing, Asparagaceae in angiosperms) is a traditional medicinal and edible plant in China. Its rhizomes can potentially enhance immunity, reduce tumor growth and the effects of aging, improve memory, and even reduce blood sugar levels (Zhao et al. 2020).

Host plants and various fungicides inhibit plant pathogens by inducing the release of excessive reactive oxygen species (ROS) and causing DNA damage, either directly or indirectly leading to cell death. The mechanisms by which the oomycete manages ROS stress resulting from plant immune responses and fungicides remains unclear. This study elucidates the role of histone acetylation in ROS-induced DNA damage responses (DDR) to adapt to stress.
