A draft genome sequence of Streptomyces sp. strain AcH 505 is presented here. The genome encodes 22 secondary metabolite gene clusters and a large arsenal of secreted proteins, and their comparative and functional analyses will help to advance our knowledge of symbiotic interactions and fungal and plant biomass degradation.
pollution of the soil environment with toxic materials from fossil burning, mining and smelting of metalliferous ores, disposal of sewage, fertilizers and pesticides, etc. has increased dramatically since the onset of industrial revolution. application of plants with ability of absorbing heavy metals is a low-cost alternative for eliminating soils from heavy metals. phytoremediation uses plants...
Transcripts for two genes expressed early in alfalfa nodule development (MsENOD40 and MsENOD2) are found in mycorrhizal roots, but not in noncolonized roots or in roots infected with the fungal pathogen Rhizoctonia solani. These same two early nodulin genes are expressed in uninoculated roots upon application of the cytokinin 6-benzylaminopurine. Correlated with the expression of the two early ...
Many studies have reported beneficial effects of yeasts on the colonization and development arbuscular mycorrhizae, thought a few also shown neutral effects. All these in common that mechanism, by which mycorrhizae interact, is little understood. Here, we explore how plant growth-promoting affect tomato plants mycorrhizal fungi. We tested influence soil Candida saitoana, Tausonia pullulans, Sac...
To evaluate the effects of biofertilizers on some physiological growth indices of a soybean cultivar (M9) under water stress condition, a study was carried out in a split plot randomized complete block design in three replications at research station of Bu Ali Sina University, Hamedan, Iran in 2012. The main plots consisted of three levels of irrigation after 50, 100 and 150 mm evaporation from...
In a study of fungi growing in various root-associated habitats in and around Picea mariana, black spruce, in northern Ontario, Canada, an examination was made of the degree to which differences in growth sites within an area of a few square kilometers might influence the structure of root-associated filamentous microfungal populations. Picea mariana roots were collected at four strongly differ...

Mycorrhizal fungi constitute a key functional group of soil biota that greatly contribute to productivity and sustainability of terrestrial ecosystems. These are ubiquitous components of most of the ecosystems throughout the world and are considered key ecological factors in governing the cycles of major plant nutrients and in sustaining the vegetation cover (van der Hejden eta!. 1998; Requena ...
