Accepted : May, 2010 Soybean [Glycine max (L.) Merill] is an important edible oilseed crop of Maharashtra, mostly grown in Marathwada region and continues to be the major source of protein and edible oil in the world. It yields more protein per hectare than most other crops and accounts for more than 63% of high protein meal and 28% of the total edible oil supply worldwide (Golbitz, 2000). The ...
Fungal pure cultures identified with both classical morphological methods and through barcoding sequences are a basic requirement for reliable reference sequences in public databases. Improved techniques for an accelerated DNA barcode reference library construction will result in considerably improved sequence databases covering a wider taxonomic range. Fast, cheap, and reliable methods for obt...
Restrictions on the use of conventional nematicides have increased the need for new methods of managing plant-parasitic nematodes. Consequently, nematode-antagonistic microbes, and active compounds produced by such organisms, are being explored as potential additions to management practices. Programs in this area at the USDA Agricultural Research Service investigate applied biocontrol agents, n...
we assessed a collection of 47 fluorescent pseudomonas spp., some with known biological control activity against certain soil-borne phytopathogenic fungi such as, macrophomina phaseolina, rhizoctonia solani, phytophthora nicotianae var. parasitica, pythium sp. and fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, hcn and protease. the resu...
Antifungal Activity of Methanolic Extracts of Some Indigenous Plants against Common Soil-borne Fungi
Present study was conducted to evaluate the fungicidal property of methanolic extracts of some indigenous plants of Karachi such as Hibiscus rosa-sinensis (leaves), Thespesia populnea (leaves, stem and fruit), Withania somnifera (leaves and stem), Solanum surattense (shoot) and Melia azedarach (fruit) against common soil-borne phytopathogens viz., Macrophomina phaseolina, Rhizoctonia solani and...
Background Malaria and helminths share the same geographical distribution in tropical Africa. Studies of the interaction of helminth and malaria co-infection in humans have been few and are mainly epidemiological, with little information on cellular immune responses. This study aimed to determine Cytokine profiles among patients co-infected with Plasmodium falciparum malaria and soil borne helm...
Arbuscular mycorrhizal (AM) fungi form symbiotic associations with most plant species in terrestrial ecosystems, and are affected by environmental variations. To reveal the impact of disturbance on an AM fungal community under future global warming, we examined the abundance and community composition of AM fungi in both soil and mixed roots in an alpine meadow on the Qinghai-Tibetan Plateau, Ch...
Soil bacteria and fungi play key roles in the functioning of terrestrial ecosystems, yet our understanding of their responses to climate change lags significantly behind that of other organisms. This gap in our understanding is particularly true for drylands, which occupy ∼41% of Earth´s surface, because no global, systematic assessments of the joint diversity of soil bacteria and fungi have be...
One hundred samples of tomato seeds were collected in 2011 and 2012 from tomato-cultivated fields in Saudi Arabia and screened for their seed-borne mycoflora. A total of 30 genera and 57 species of fungi were recovered from the collected seed samples using agar plate and deep-freezing blotter methods. The two methods differed as regards the frequency of recovered seed-borne fungi. Seven fungi a...
