Inhibitory Effects and Mechanisms of Perilla Essential Oil and Perillaldehyde against Chestnut Pathogen Botryosphaeria dothidea

mycolabadmin

Chestnut rot caused by the fungus Botryosphaeria dothidea is a major problem during fruit storage. Researchers found that essential oil from perilla plants and its main component perillaldehyde effectively kill this fungus by damaging its cell walls and membranes. This natural solution could replace harmful synthetic fungicides while keeping chestnuts fresh longer during storage.

A rapid and efficient in vivo inoculation method for introducing tree stem canker pathogens onto leaves: suitable for large-scale assessment of resistance in poplar breeding progeny

mycolabadmin

Researchers developed a faster, easier method to test whether poplar trees can resist stem canker diseases caused by fungi. Instead of using time-consuming tests on woody stems, they inoculated fungal pathogens directly onto leaves and measured disease symptoms after 5 days. This new leaf-based method works just as well as traditional methods but is much quicker and requires fewer resources, making it ideal for testing large numbers of hybrid poplar trees in breeding programs.

Inhibitory Effects and Mechanisms of Perilla Essential Oil and Perillaldehyde against Chestnut Pathogen Botryosphaeria dothidea

mycolabadmin

Chestnuts often rot during storage due to fungal infection. This study found that oil extracted from perilla leaves, particularly a compound called perillaldehyde, effectively prevents the fungus Botryosphaeria dothidea from growing. The antifungal compounds work by breaking down the protective layers of the fungal cells, causing them to leak and die. When applied to stored chestnuts, this natural oil significantly extends their shelf life without harming human health.

Scientists developed a faster and easier way to test whether poplar trees are resistant to stem canker diseases caused by fungi. Instead of using traditional time-consuming stem tests, they inoculate fungal pathogens directly onto leaves, which shows results in just 5 days. This new leaf-based method uses abundant, readily available leaf tissue and can test many poplar breeding candidates quickly and cheaply, making it ideal for developing disease-resistant poplar varieties.

Bacillus velezensis LMY3-5 for the biocontrol of soft rot in kiwifruit: antifungal action and underlying mechanisms

mycolabadmin

Scientists discovered a beneficial bacteria called Bacillus velezensis that can effectively prevent soft rot disease in kiwifruit, which causes serious damage during storage. The bacteria works by producing natural antimicrobial compounds that damage the fungal pathogen’s cell walls and membranes, stopping it from growing. This biocontrol approach offers an environmentally friendly alternative to chemical fungicides, reducing pesticide residues while maintaining fruit quality and safety.
