This study sought to develop a biological control agent against gray mold disease caused by Botrytis cinerea in tomato using a strain of Streptomyces, which showed significant antagonistic activity against B. cinerea. Such strain (C51) was screened by dual culture method from a total of 78 actinomycetes and was identified as Streptomyces nobilis by morphological, biochemical and molecular analy...

Bis(2,3-dibromo-4,5-dihydroxybenzyl) ether (BDDE) is a bromophenol isolated from marine algae. Previous reports have shown that BDDE possesses cytotoxic and antibacterial activity. In the present study, we demonstrate that BDDE displays broad-spectrum antifungal activities, especially on Botrytis cinerea. BDDE inhibits the growth of B. cinerea cultured on a solid medium of potato dextrose agar ...

The efficacy of thyme and savory essential oils were investigated against Botrytis cinerea on apple fruit. Apples treated with thyme and savory essential oils showed significantly lower gray mold severity and incidence. Thyme essential oil at 1% concentration showed the highest efficacy, with lower disease incidence and smaller lesion diameter. The expression of specific pathogenesis-related (P...

The circadian clock, an internal time-keeping mechanism, allows plants to anticipate regular changes in the environment, such as light and dark, and biotic challenges such as pathogens and herbivores. Here, we demonstrate that the plant circadian clock influences susceptibility to the necrotrophic fungal pathogen, Botrytis cinerea. Arabidopsis plants show differential susceptibility to B. ciner...

Upon pathogen infection, activation of immune response requires effective transcriptional reprogramming that regulates inducible expression of a large set of defense genes. A number of ethylene-responsive factor transcription factors have been shown to play critical roles in regulating immune responses in plants. In the present study, we explored the functions of Arabidopsis AtERF15 in immune r...

Edible coatings were prepared with 1% (w/v) chitosan (CH) incorporated 0.05%, 0.25%, or 0.5% tea seed oil (TSO). The physicochemical properties and antifungal ability on Botrytis cinerea (B. cinerea) of the films investigated. CH TSO applied to preserve pears (Pyrus pyrifolia Nakai) then fungal decay, respiration rate, other characters determined throughout storage at 25 °C 85 ± 5% relative hum...

Study of the tropic responses of Botrytis cinerea and Osmunda cinnamomea spores to blue light shows the photoreceptor molecules to be highly dichroic and oriented: in Botrytis their axes of maximum absorption lie perpendicular to the nearby cell surface; in Osmunda, parallel. The chief evidence lies in a comparison of their responses to plane polarized light-both germinate parallel to the vibra...

Botrytized wines are dessert made from overripe grapes infected by Botrytis cinerea known as “botrytized grapes” or “noble rot”. They favored human for their health promoting antioxidants and pleasant flavor. However, production is low natural botrytized rare in most vineyards worldwide. That is, not all B. become grapes. The formation of determined the interactions between microbiota, includin...
