Effects of Thifluzamide Treatment on the Production of Cell Wall Degrading Enzymes in Rhizoctonia solani and Phenylpropane Metabolism in Pear Fruit

mycolabadmin

A new fungicide called thifluzamide was tested on pear fruits infected with a fungus that causes rot. The fungicide works in two ways: it stops the fungus from producing enzymes that break down plant cell walls, and it boosts the pear’s natural defense system by increasing protective compounds like flavonoids and phenolic acids. This dual action makes thifluzamide a promising treatment for preventing fruit rot during storage and transport.

Sunlight-sensitive carbon dots for plant immunity priming and pathogen defence

mycolabadmin

Scientists developed special tiny carbon particles that respond to sunlight by producing molecules that strengthen plant defenses against fungi. When sprayed on plants like tomato and tobacco, these particles trigger the plant’s natural immune system, reducing fungal diseases by 12-44% without harming the plant. At higher concentrations with continuous sunlight, the particles can directly kill fungal pathogens. This eco-friendly approach offers a sustainable alternative to chemical fungicides while maintaining crop yields.

Targeted metabolomic and transcriptomic reveal the regulatory network of ultrasound on polyphenol biosynthesis in tender coconut flesh during storage

mycolabadmin

Researchers studied how ultrasound treatment affects the polyphenolic compounds (natural antioxidants) in coconut flesh during storage. By analyzing both the chemicals and genes involved, they found that ultrasound helps preserve important polyphenols like catechin and epicatechin by controlling the expression of genes that break them down. This discovery could help extend the shelf life of tender coconut products and maintain their nutritional value.

New wine in old skins: Scopoletin biosynthesis in cotton

mycolabadmin

Cotton farmers face significant crop losses from a soil-dwelling fungus called Verticillium dahliae. Scientists discovered that cotton plants can protect themselves by producing a compound called scopoletin, which damages and kills this fungus. By understanding how cotton activates the genes that make scopoletin, researchers may be able to genetically engineer more disease-resistant cotton varieties, providing farmers with a sustainable alternative to chemical pesticides.
