In order to investigate the genetic differentiation of Sinorhizobium strains nodulating Glycine max and related microevolutionary mechanisms, three housekeeping genes (SMc00019, truA, and thrA) and 16 symbiosis-related genes on the chromosome (7 genes), pSymA (6 genes), and pSymB (3 genes) were analyzed. Five distinct species were identified among the test strains by calculating the average nuc...

objective: the aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of p. sojae from iran. methods: during 2005–2007, 142 isolates of phytophthora sojae were collected from soil samples and diseased soybean plants from lorestan, mazandaran, golestan and ardabil provinces. races of the isolates were determined. dna of p. sojae fifty isolates was amplifi...

the aluminum oxide materials are widely used in ceramics, refractories and abrasives due to their hardness, chemical inertness, high melting point, non-volatility and resistance to oxidation and corrosion. the paper describes work done on synthesis of α-alumina by using the simple, non-expensive solution combustion method using glycine as fuel.aluminum oxide (al2o3) nanoparticles were synthesiz...

Abstract This study aims to evaluate the capability of extracellular protease hydrolyze keratin substrates local poultry feathers and observing amino acid profile. The indigenous strains ( Bacillus cereus TD5B, LS2B, Pseudomonas sp. PK4) were used in this study, obtained data analysed descriptively. TD5B has a maximum activity at 0.003849062 unit/ml 0.000310042 on casein commercial substrates. ...

Streptomyces sp. and Trichoderma are soil microorganisms isolated from shallot fields that can act as biological agents increase crop production. Nezara viridula, the southern green stink bug, is leading pest of soybean during generative period, which cause damage up to 80%. This study aimed determine efficacy a liquid biopesticide formula using mixture coconut water potato extract containing u...

Soybeans [Glycine max (L.) Merrill] have great economic prominence in the world, and soil management systems can directly interfere with their yield through changes physical-hydric properties. Thus, aim of this research was to verify relationship between components, physiological traits, root development, properties soybean yields grown under conventional tillage no-tillage systems. The experim...
