The area planted with avocado crops in Colombia has been growing rapidly recent years, especially for export varieties such as Hass. increase coincided increased phytosanitary problems, where pathogens fungi of the genus Verticillium spp. are becoming economic importance. objective this study was to evaluate different control strategies wilt disease caused by spp., under vitro, net house, and f...

Fungi profoundly affect nearly all terrestrial ecological processes and events; accurate information on the fungal component is required to adequately understand how ecosystems function (Trappe and Luoma 1992). When fungal mycelia form particular associations with a host plant’s fine roots, a symbiotic organ forms, called a mycorrhiza. Through this structure the plant provides carbohydrates to ...

to study the effect of chemical and biological fertilizers on growth and essential oil content of lavender (lavandula angustifolia mill.), the present work was conducted in 2012-2013 at the experimental field of alborz research station of the research institute of forests and rangelands, karaj, iran. the experiment was conducted in factorial in the form of a randomized complete block design wit...

Arbuscular mycorrhizal fungi (AMF) are expected to be one of the key drivers determining the diversity of natural plant communities, especially in nutrient-poor and dry habitats. Several previous studies have explored the importance of AMF for the composition of plant communities in various types of habitats. Surprisingly, studies of the role of AMF in nutrient-poor dry grassland communities do...

Regulation by arbuscular mycorrhizal symbiosis of three tomato plasma membrane H+-ATPase genes (LHA1, LHA2 and LHA4) has been analysed in wild-type and mycorrhiza-defective tomato plants. Expression of these genes was differentially regulated in leaves and roots of both tomato phenotypes after inoculation with Glomus mosseae.

to evaluate the effect of arbuscular mycorrhizal fungi under water deficit stress on linseed, a field experiment was conducted as split-plot in rcbd design with three replications at the research station of faculty of agriculture at shahrekord university in 2013. water deficit stress at four levels of no stress, mild, medium and severe stress as main factor and inoculation with glomus intraradi...
