Özet
Background Triticum monococcum ssp. monococcum is an ancestral wheat species originated from Karacadag Mountain of Turkey more than ten thousand years ago. Because of environmental and anthropogenic effects, food supply and demand are not balanced. Agricultural activities such as breeding, and fertilization are important to sustain the balance. Conventional breeding and fertilization applications usually neglect contribution of plant related hologenomes in agricultural yield. The disruption of plant growth promoting microorganisms results in intensive usage of chemical fertilizers. The harmony between plant and plant-associated microorganisms is important for sustainability. In this study, isolation, biochemical characterization, and impact on plant growth parameters of natural bacteria associated with Triticum monococcum ssp. monococcum hologenome were aimed. Methods and results The collection of root samples and isolations of the root-associated bacterial species were carried out from local wheat lands. According to interpretation of three identification methods (MALDI-TOF, 16S rDNA, 16S-23S rDNA) eight isolates are Arthrobacter spp. ESU164, Arthrobacter spp. ESU193, Pseudomonas spp. ESU131, Pseudomonas spp. ESU141, Pseudomonas poae strain ESU182, Pseudomonas thivervalensis strain ESU192, Pseudomonas spp. ESU1531, Bacillus subtilis strain ESU181. For each isolate we investigated biochemical properties especially nitrogen fixation, phosphate solubilization, and indole-3-acetic acid production abilities. The results show that all isolates are nitrogen fixers and the best phosphate solubilizer have been reported as Pseudomonas spp. ESU131 with 2.805 +/- 0.439. Conclusions All isolates are indole-3-acetic acid productors. 2 isolates affected the coleoptile lengths, 7 bacterial isolates showed statistically positive effect on root number, and 5 isolates promote the root lengths and the root fresh weights.
