background and objectives: soil salinity and zn deficiency are among the most important limiting factors for growth and yields of pistachio trees in many regions of iran, especially in the rafsanjan area. the use of plant growth promoting rhizobacteria (pgpr) is new strategies to reduce destructive effects of salinity and improvement of nutrient availability. this study investigated the interac...

Hypotheses in which sorghum seedlings [Sorghum bicolor (L.) Moench] of different genotypes will differentially modify soil microorganisms and will affect subsequent planting of wheat (Triticum aestivum L.) seedlings, were tested. Wheat cultivar Lewjain, and sorghum genotypes Redlan and RTx433, were planted into soils previously planted with wheat or sorghum in growth chamber experiments. Total ...

A rapid identification of phytopathogenic bacteria was available at species level by the direct colony thin-layer chromatography. Distinct difference was observed in chromatographic profile between Emoirza’a chrysanthemi and E. carotovora subsp. carotovora. In the case of Erwinia carotovora subsp. carotovora, a characteristic spot at Rf 0.57 appeared concomitantly with a common spot at 0.62. Th...

Our earlier studies had shown that the two pseudomonads, Pseudomonas cepacia and Pseudomonas maltophilia, were organisms that were highly resistant to most antibiotics. The present study was undertaken to determine the susceptibility of these bacteria to trimethoprim and the trimethoprim-sulfamethoxazole combination which has been used with apparent success in treating infections caused by thes...

Compared to those of dicot-infecting bacteria, the available genome sequences of bacteria that infect wheat and barley are limited. Herein, we report the draft genome sequences of four pseudomonads originally isolated from these cereals. These genome sequences provide a useful resource for comparative analyses within the genus and for cross-kingdom analyses of plant pathogenesis.
