“…Soils of our country are a source of microbial diversity that should be explored for the potential applications in biotechnology and conservation. Many works of study show that application of plant-beneficial microorganisms in agricultural lands increases the crop productivity (Kantar et al, 2003;Öǧütçü et al, 2008;Öǧütçü et al, 2010). Additionally, it is an ecofriendly approach that can help the economy of local farmers.…”

“…Bacterial strains isolated from high altitude Himalayan regions have been shown to be able to solubilize phosphate at low temperatures (Adikari et al, 2021). In our country, effectes of bacteria isolated from Erzurum has been tested on chickpeas (Kantar et al, 2003;Öǧütçü et al, 2008;Öǧütçü et al, 2010). But to our knowledge, there is no work on psychrophilic microorganism isolation in Antalya region.…”

Only a portion of chemical fertilizers applied to soil can be used by plants, because nutrients can become insoluble in soil. Application of biofertilizers can make the nutrients bio-available for plants. This practice would be beneficial for both plant productivity and the environment. Aim of this study was to isolate and compare growth rates of bacterial strains isolated from low altitude and high altitude regions of Antalya. Our results showed that, bacterial strains isolated from high alitudes have higher growth rates at room temperature (15-25 C) and temperatures as low as 2 C, compared to strains isolated from low altitudes. This suggests that strains that can grow at 2 C also would have higher enzymatic activities at low temperatures which makes them better candidates for development of biofertilizers. Using cold adapted biofertilizer would have a positive effect on plant productivity in agricultural areas located in cold regions of Türkiye. Therefore, isolation of these organisms and testing of their biofertilizer potential is important for our agricultural applications.

Genetic variation in mutualistic and antagonistic interactions in an invasive legume

Mutualists may play an important role in invasion success. The ability to take advantage of novel mutualists or survive and reproduce despite a lack of mutualists may facilitate invasion by those individuals with such traits. Here, we used two greenhouse studies to examine how soil microbial communities in general and mutualistic rhizobia in particular affect the performance of a legume species (Medicago polymorpha) that has invaded five continents. We performed two plant growth experiments with Medicago polymorpha, inoculating them with soil slurries in one experiment or rhizobial cultures in another experiment. For both experiments, we compared the growth of Medicago in competition with conspecific or heterospecific plants and examined variation among plant genotypes collected from the native and introduced ranges. We found that all genotypes experienced similar increases in biomass and formed more nodules that house rhizobia bacteria when inoculated with soil from a previously invaded site, compared to uninoculated plants or plants inoculated with soil from uninvaded and low invasion sites. In a second experiment, plants inoculated with rhizobia generally produced more biomass, had greater tolerance to interspecific competition, and had greater effects on competitor biomass than uninoculated plants. However, plant genotypes collected from the native range benefited more from rhizobia and were less tolerant of competition relative to genotypes collected from the introduced range. In the introduced range, compatible mutualists may not be readily available but competition is intense, causing Medicago to evolve to benefit less from interactions with rhizobia mutualists, while simultaneously becoming more tolerant of competition.

Aims To assess the symbiotic effectiveness, tolerance to abiotic stress factors and phosphate solubilizing ability of new chickpea root-nodule bacteria. Methods Symbiotic effectiveness, abiotic stress tolerance and phosphate solubilizing ability of ten new chickpea rhizobial strains collected from soils were evaluated using laboratory and glasshouse experiments. Results Six of the ten strains were symbiotically efficient with diversity between those and the commercial chickpea strain CC1192. High temperatures significantly affected strain survival in liquid and peat carrier. Peat carrier offered greater protection. Above 37 °C, strain infectivity decreased with no correlation between strain origin and their infectivity after exposure. Three of the new strains and CC1192 produced optimum growth and survival at pH 6.8 and at two lower pH’s of 4.4 and 5.4 were able to neutralize the growth medium while the other seven strains at high pH were able to either neutralize or acidify the growth medium. Strain survival was significantly higher at increased salt concentrations of NaCl compared to CaCl2. At 3% NaCl concentration, 8 strains survived while at 3% CaCl2 only 3 survived. Many strains were resistant to more than one antibiotic. All strains were able to solubilize phosphate. The ratio between the most efficient strain and the least was 3:1. Conclusions Chickpea rhizobia strains sourced from soils in Narrabri New South Wales and Kununurra in Western Australia differed in expressed traits from the commercial strain CC1192. These unique traits could provide additional tools for rhizobial strain selection to benefit chickpea production in different soil environments.
