Summary: The primary postharvest diseases of kiwifruit, blue and gray mold, are effectively controlled by the antagonistic yeast Wickerhamomyces anomalus. The antifungal activity of this yeast is attributed to several mechanisms, such as inhibition of fungal growth, rapid colonization on kiwifruit surfaces and wounds, attachment to fungal mycelia, strong biofilm formation, and production of volatile organic compounds (VOCs) with antifungal properties. VOCs produced in YPD medium showed stronger inhibitory effects than those produced in NYDA medium, with 2-phenethyl acetate and 1-butanol, 3-methyl- being the main VOCs responsible for the antifungal activity.

Summary: In this study, three bacterial strains from rice and wheat seeds were found to have antifungal effects against wheat blast. It was discovered that volatile organic compounds (VOCs) produced by these bacteria are responsible for the inhibition of mycelial growth and sporulation of the pathogen. Biocontrol assays using detached wheat leaves confirmed the effectiveness of these VOCs. Gas chromatography-mass spectrometry analysis identified a total of 39 VOCs from the four bacterial treatments, with 11 VOCs produced by all treatments. These findings suggest that VOCs from Bacillus spp. are effective compounds for suppressing the growth and sporulation of wheat blast.

Summary: Tetrahydrocannabinols (THCs) have been investigated for their potential therapeutic effects in cancer due to their cannabimimetic properties. These compounds antagonize the CB1 and CB2 cannabinoid receptors, which are essential for controlling cell survival and proliferation. Preclinical research has shown that THCs reduce tumor progression by stimulating apoptosis and autophagy and inhibiting metastasis and angiogenesis. However, the efficacy of THCs as anticancer agents depends on various factors, such as the tumor origin, expression of cannabinoid receptors, and dosage and type of THC.

Summary: Salinity stress is a major limitation to crop production worldwide. The application of organic amendments can mitigate the negative effects of salinity and improve the growth, yield, and grain quality of crops. In this study, the impacts of farmyard manure (FYM) and press mud (PM) on rice crop under salinity stress were investigated. The results showed that salinity stress had deleterious effects on the growth, yield, and grain quality of rice, but the application of organic amendments effectively offset these effects and improved the crop performance. The combined application of FYM and PM further enhanced the growth, yield, and grain bio-fortification of rice. Therefore, the use of FYM and PM can be considered as a good practice for better rice production in salt-affected soils.
