Natural geranyl compounds are known to exhibit important biological activities. In this work a series of geranylphenols were synthesized to evaluate their effect on the mycelial growth of Botrytis cinerea. Geranyl derivatives were synthesized by direct geranylation reactions between the corresponding phenol derivatives and geraniol, using BF3.OEt2 as catalyst and AgNO3 as secondary catalyst. Pr...
Bacillus subtilis J-5 was isolated from tomato rhizosphere soil and exhibited strong inhibitory activity against Botrytis cinerea To shed light on the molecular mechanism underlying the biological control on phytopathogens, the whole genome of this strain was sequenced. Genes encoding antimicrobial compounds and the regulatory systems were identified in the genome.
(-)-alpha-Pinene (1), a major constituent of many aromatic plants was biotransformed by the plant pathogenic fungus, Botrytis cinerea to afford three new metabolites, characterized as 3beta-hydroxy-(-)-beta-pinene (10%) (3), 9-hydroxy-(-)-a-pinene (12%) (4), 4beta-hydroxy-(-)-alpha-pinene-6-one (16%) (5) by physical and spectroscopic methods. A known metabolite verbenone (2) was also obtained.
توت فرنگی با نام علمی ananassa duch× fragaria یک گیاه علفی دائمی از خانواده rosaceae و از زیر خانواده rosoidae می باشد. کیفیت توت فرنگی به ظاهر میوه (رنگ، اندازه، شکل، وجود یا عدم وجود عیب)، سفتی بافت، طعم و ارزش غذایی آن بستگی دارد که همه این شاخص ها به شرایط میوه در زمان برداشت و تغییرات ایجاد شده در طول دوره پس از برداشت بستگی دارد. توت فرنگی به دلیل تنفس بالا، مقدار آب زیاد، فعالیت متابولیک...
