Casbene is a macrocyclic diterpene hydrocarbon that is produced in young castor bean (Ricinus communis L.) seedlings after they are exposed to Rhizopus stolonifer or other fungi. The activities of enzymes that participate in casbene biosynthesis were measured in cell-free extracts of 67-hour castor bean seedlings (a) that had been exposed to R. stolonifer spores 18 hours prior to the preparatio...

Deoxyribonucleic acid (DNA)-dependent DNA polymerase was purified several hundredfold from germinated and ungerminated spores of the fungus Rhizopus stolonifer. The partially purified enzymes from both spore stages exhibited identical characteristics; incorporation of [(3)H]deoxythymidine monophosphate into DNA required Mg(2+), DNA, a reducing agent, and the simultaneous presence of deoxyguanos...

many fungi cause sugar beet root rot during various stages of the plant growth. among them rhizoctonia spp. induce crown rot, dry rot and violet root rot on sugar beet (whitney and duffos,1986). root rot caused by phytophthora drechsleri has been observed in fields with excessive moisture (habibi,1975). pythium aphanidermatum has been recognized as one of the causal agents of sugar beet, dampin...

Postharvest deterioration has been a major problem associated with yam storage for both famers and traders it is caused mostly by micro-organisms especially fungi. During the of yam, many organisms such as Aspergillus flavus, niger, Penicillium citrinum Rhizopus stolonifer are often reported to cause rotting stored yams. The aim this research find out antifungal effect some commonly used anti-d...

L. stoechas subsp. luisieri is one of the five spontaneous species genus Lavandula that occurs spontaneously in Portugal. The chemical profile and antifungal activity essential oils were investigated. oil two phenological stages was isolated by hydrodistillation their components analyzed GC-FID/GC-MS. minimum inhibitory concentration (MIC) fungicidal (MFC) both determinate to verify against dif...
