In order to establish the molecular taxonomy of the genus Rhizopus, all described species of the genus were collected and the nucleotide sequences of the internal transcribed spacer of the rRNA gene (rDNA ITS), actin, and translation elongation factor 1alpha (EF-1alpha) were determined. Quantitative real-time PCR revealed that R. americanus had a R. stolonifer-type ITS sequence as the dominant ...
Postharvest diseases cause losses in a wide variety of crops around the world. Irradiation, a useful nonchemical approach, has been used as an alternative treatment for fungicide to control plant fungal pathogens. For a preliminary study, ionizing radiations (gamma, X-ray, or e-beam irradiation) were evaluated for their antifungal activity against Botrytis cinerea, Penicillium expansum, and Rhi...
This research aimed to develop a rapid and nondestructive method to model the growth and discrimination of spoilage fungi, like Botrytis cinerea, Rhizopus stolonifer and Colletotrichum acutatum, based on hyperspectral imaging system (HIS). A hyperspectral imaging system was used to measure the spectral response of fungi inoculated on potato dextrose agar plates and stored at 28°C and 85% RH. Th...
سی و هفت جدایه از جنس rhizopus به دست آمده از میزبان های مختلف در استان های تهران، آذربایجان غربی، یزد و کردستان جهت مطالعات تاکسونومیکی مورد بررسی قرار گرفتند. منطقه its شامل ژن 5.8s و مناطق d1-d2 مربوط به dna ریبوزومی با استفاده از جفت آغازگرهای its1/nl4 تکثیر شدند. محصولات تکثیر شده توسط pcr با استفاده از آنزیمهای برشی haeiii، rsai، hinfi و mspi مورد هضم آنزیمی قرار گرفتند و هفت جدایه نماین...
Rhizopus stolonifer invades sweetpotato roots through injuries and infected roots are rapidly consumed by a soft rot. However, not all injuries are equally susceptible to infection; shallow injuries (1–2 mm deep) are less prone to infection than deeper injuries ( 5 mm deep). The presence of antifungal compounds in external tissues may partially explain the resistance of shallow injuries to infe...
The antifungal efficacy of seed extracts (propanol, ethanol, methanol and sterile deionised water) of Camelina sativa cv. Calena (EC643910) against Rhizopus stolonifer was investigated by agar disc diffusion method. Among all extracts, methanolic seed extract (Disc 3) showed significant activity against R. stolonifer. However, no activity was observed against rest of the extracts (Disc 1, 2 and...
Pathogen aggressiveness on the host was studied as one of the influencing factors in the variability of the efficiency of biocontrol by Pantoea agglomerans. The effect of the relative dose of the pathogen and biocontrol agent (BCA) on efficacy of biocontrol was analyzed in six postharvest pathogens (Rhizopus stolonifer, Botrytis cinerea, Penicillium expansum, Monilinia laxa, Penicillium digitat...
