Metcalfa pruinosa (Say, 1830) is an invasive, gregarious sap-sucking insect that spreads rapidly through Ukraine and now detects in Kyiv city, the Autonomous Republic of Crimea, Donetsk, Dnipropetrovsk, Zakarpattia, Odesa, Kharkiv, regions. Additionally, this parasitizes more than 300 species plants, including common hop (Humulus lupulus L.). H. a valuable industrial crop grown many countries, ...

This study presents the findings on influence of raspberry varieties species composition micromycetes in rhizosphere soil and vegetative organs plants organic production. The mycobiota Joan J Himbo-Top was analysed during plant ontogeny phytopathogenic microspecies leaves determined. It found that population is dominated by fungi: Septoria rubi, West, Botrytis cinerea, Pers, Aspergillus niger, ...

pectinases have multiple nature and various forms which are necessary for the hydrolysis of pectin in several conventional industrial and natural processes. in this investigation fourteen fungal strains which isolated from agricultural soils ,were screened for pectinase activity. pectinase activity were measured in vitro by assaying released reducing sugar from pectin as sole carbon source. asp...

In this study, four specimens belonging to Karaj mycoflora were examined. According to the results, two form – species; Diplosporonema delastrei, on Silene latifolia subsp. persica and Piggotia ulmi, on Ulmus sp. are reported with new names. For some of the identified fungal specimens, new hosts (matrix nova) are introduced. Moreover, many taxa such as , Marssonina kriegeriana on Salix sp.,  Se...

abstract- desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. a pcr-based method was developed for the identification of 3 major desert truffles of iran: terfezia claveryi, tirmania pinoyi and tirmania nivea based on internal transcribed spacers of rdna. two specific pcr primers were designed for t. claveryi, 4 for t. pinoyi, and 2 for ...

In the conditions of a small-scale experiment on natural infectious background (Belgorod, Russia), threefold excess CFU values rhizosphere Melilotus officinalis was revealed in comparison with fallow soil, but abundance typical species and control 63% 77%, respectively. The Jacquard coefficient proved high similarity mycocomplexes M. (33%). core microcomplex sweet clover is Trichoderma lignorum...

The survival of fungi in Antarctica is a consequence both ecological selection and evolutionary adaptation expressed at the physiological, metabolic, structural, genetic levels. study biological diversity Antarctic micromycetes will help us to better understand pathways fungal dispersal biosphere, as well broaden our understanding their role extreme ecosystems. In addition, habitats are promisi...
