all of the tea plantations in iran are concentrated in the caspian sea region on soils previously developed under deciduous natural forests. this research conducted to study the effect of land use change (from forest to tea) on selected physico-chemical and mineralogical properties of soils under humid climate and mountainous landscape in northern iran. three transects facing west to northwest ...

response to soil compaction associated with soil and crop type, and soil wetness at the time of load application and weather in Central and Eastern Europe are reviewed. The effects of soil compaction on the morphological and anatomical modifications of the roots were shown. The influence of soil compaction on plasticity in root growth and functioning in relation to structural discontinuity is d...

cadmium as a heavy metal is also considered as a serious threat for the environment. this element is accumulated in soil through industrial processes as well as phosphate fertilizers and aggregates into the food chain.this study was conducted in order to investigate of different levels of cadmium effects on growth features of rapeseed(brassica napus l.) plants. root and shoot weight and height,...

Most terrestrial ecosystems are nitrogen (N)-limited. The elucidation of the multivariate relationships among environmental drivers, leaf morphological traits, and foliar N of dominant species which are critical to the functioning of forests remains a critical challenge for ecologists. We sampled leaves of Quercus wutaishanica across a broad natural gradient in the Loess Plateau, China, and emp...

In this study, we reported the morphogenetic analysis and genome sequence by genomic analysis of the newly isolated staphylococcal phage SMSAP5 from soil of slaughterhouses for cattle. Based on transmission electron microscopy evident morphology, phage SMSAP5 belonged to the Siphoviridae family. Phage SMSAP5 had a double-stranded DNA genome with a length of 45,552 bp and 33 % G+C content. Bioin...

Cells are active components in their environment and constantly adjusting their performance to improve extracellular milieu changing. This approach is reflected their tends of maintaining intracellular homeostasis. When the cells encounter stress or pathologic stimuli, they can undergo a new manner (adaptation) and new steady state for achieving viability and function. If the external stress is...

Two new fungal species of the genus Talaromyces, Talaromyces purpurogenus and Talaromyces trachyspermus from the Trichocomaceae family, were recovered during an investigation of fungal communities in soil collected from the Gangwon-do and Jeollanam-do provinces of Korea. These two species have not been previously officially reported from Korea. In this study, detailed descriptions of internal t...

The taxonomic position of a soil isolate, strain 13.4T, was established using a polyphasic approach. The organism was found to have chemical and morphological properties consistent with its classification in the genus Amycolatopsis. Phylogenetic analysis of the strain based on its 16S rDNA sequence showed that it forms a distinct phyletic line within members of the genus Amycolatopsis. The orga...

An isolate, KC46 active against clinical resistant strains was isolated from Indian soil. Based on morphological features and biochemical characteristics it was identified as Streptomyces noursei. The active compounds isolated from KC46 using various fermentation methods (fermentation in shake flasks, in P-flasks, and also in a fermenter, using starch casein nitrate medium containing zinc sulph...
