The impact of carvacrol on the larval gut bacterial structure and function of .

Introduction: The gut bacteria of insects play an important role in regulating their metabolism, immune system and metabolizing pesticides. Our previous results indicate that carvacrol has certain gastric toxic activity on larvae and affects their detoxification metabolism at the mRNA level. However, the impact of carvacrol on the gut bacteria of larvae has been unclear.

The photoactivated antifungal activity and possible mode of action of sodium pheophorbide a on causing leaf spot blight in .

Introduction: Sodium pheophorbide a (SPA) is a natural plant-derived photosensitizer, with high photoactivated antifungal activity against some phytopathogenic fungi. However, its fungicidal effect on , a novel pathogen that causes leaf spot blight, is unclear.

Methods: In the present study, we explored its inhibitory effects on spore germination and mycelial growth of .

Antifungal Activity of 6-Methylcoumarin against and Its Possible Mechanism of Action.

canker of apple (VCA) caused by severely affected apple production in east Asia. With the increase in drug resistance, there is an urgent need for efficient and environmentally friendly antifungal agents. Coumarins have attracted much attention due to their excellent antimicrobial activity against plant pathogens.

Inhibitory effect and mechanism of action of juniper essential oil on gray mold in cherry tomatoes.

Juniper essential oil (JEO), which is mostly known as an immune system booster and effective detoxifier, has substantial antimicrobial activity. A comparison of the inhibitory effects of three plant essential oils from juniper (), cedarwood (), and cypress () on four plant pathogenic fungi indicated that JEO was the most effective at inhibiting the growth of gray mold (). Additional studies were subsequently conducted to explore the and antifungal activity and possible mechanism of JEO against .

First Report of Black Spot Needle Blight of Pinus sylvestris var. mongolica Litv. Caused by Heterotruncatella spartii in China.

Pinus sylvestris var. mongolica Litv. (Pinales: Pinaceae) is an excellent tree for soil and water conservation in Northeast China.

Transcriptomic analysis of interactions between Lymantria dispar larvae and carvacrol.

Due to its biological activity, carvacrol (CAR) is widely used in medicine, agriculture, and forestry. Our previous studies showed that in Lymantria dispar larvae, CAR treatment can induce the production of antifeedants and lead to growth inhibition and death of larvae. However, the effect CAR exerts on RNA levels in L.

Inhibitory effects and mechanisms of vanillin on gray mold and black rot of cherry tomatoes.

Vanillin is a natural antimicrobial agent; however, there are few reports on its antifungal effect on postharvest pathogenic fungi. This study aimed to investigate the in vivo and in vitro antifungal activities of vanillin against gray mold (caused by B. cinerea) and black rot (caused by A.

Transcriptome and cell wall degrading enzyme-related gene analysis of Pestalotiopsis neglecta in response to sodium pheophorbide a.

Sodium pheophorbide a (SPA) is a new alternative fungicide with low toxicity and high efficiency, which has high fungicidal activity against Pestalotiopsis neglecta, a pathogen that causes black spot needle blight of Pinus sylvestris var. mongolica. To utilize SPA for plant disease control, understanding its antifungal mechanism is essential.
