“…Recent researches showed that the detrimental effects of various chemical fertilizers utilized in agricultural areas have caused to researchers to find alternative solutions and methods [4]. PGPR is the one of the most promising alternative application in agricultural areas since past decades because of their beneficial effects on agricultural lands, product yield, soil and plant health [18].…”

“…Because nitrogen (N 2 ) is a unique element for all living organism and plants cannot utilize it straightly. Therefore, nitrogenfixation have significant role in plant growth and development [4]. The other nitrogen source for plants is ammonia because of its fruitful nitrogen containing molecules [29].…”

“…This situation has revealed the necessity of determining various alternative strategies to feed the growing population [1,2]. With the start of the green revolution, there has been a significant increase in the www.dergipark.gov.tr/tdfd use of pesticides and chemical fertilizers in the strategies developed in this field and an alternative solution has been produced to meet the demands in the short term [3,4]. However, the production costs of these chemical fertilizers have increased and their improper use have caused both economic and environmental destruction such as; high costs, decreasing of microbial diversity and soil productivity, arising of phytopathogens and insect resistance and pollution of environment and agricultural lands [3][4][5].…”

The present study aimed to isolate potential plant growth rhizobacteria (PGPR) from various crops in agricultural areas in Ağrı-Turkey and their characterization. For this goal, rhizospheric soil samples of wheat, barley and trefoil were collected from 12 different locations in Ağrı province. Bacteria isolation studies were carried out with these rhizospheric samples. Then, to determine the PGPR properties of each isolate; nitrogen fixation, phosphate dissolution, siderophore, ammonia and HCN production tests were performed. Molecular identification of active isolates determined as suitable for development of biofertilizers, biostimulants and/or bioprotectants was done by PCR and sequencing applications performed with universal 16S rRNA primers. According to the results, 29 potential PGPR isolates were determined and their molecular characterization was done. These isolates were distributed in Arthrobacter, Bacillus, Brevibacterium, Enterobacter, Pantoea, Pseudomonas, Microbacterium and Stenotrophomonas according to their 16S rRNA sequence similarities.

“…Regardless of being the second most important macronutrient required for plant growth and development next to nitrogen, phosphorus (P) is unavailable to plants due to its least mobility and poor solubility. P plays an important role in carrying out metabolic processes such as photosynthesis, signal transduction, cell division, nutrient transport, and macromolecular biosynthesis, increasing the efficiency of nitrogen fixation in legumes and respiration in plants (Alaylar et al, 2019;Billah et al, 2019). It is a fundamental component of enzymes, coenzymes, proteins, phospholipids, nucleotides, and nucleic acids (Kafle et al, 2019;Kalayu, 2019;Alayler et al, 2020).…”

Study of Pyrroloquinoline Quinine From Phosphate-Solubilizing Microbes Responsible for Plant Growth: In silico Approach

et al. 2021

Plants cannot uptake the insoluble form of phosphate from soil. Phosphate-solubilizing microbes (PSMs) release gluconic acid (C6H12O7) that is synthesized by the interaction between co-factor pyrroloquinoline quinine (PQQ) and glucose dehydrogenase within themselves and hence convert the insoluble phosphate into a soluble form. Phylogenetic analyses based on individual sequences of PqqA–PqqE proteins involved in the PQQ biosynthetic pathway manifested clear clustering formation of the selected species according to their respective genera such as Pantoea, Rouxiella, Rahnella, Kosakonia, Mixta, Cronobacter, and Serratia. In multiple sequence alignment (MSA), numerous semi-conserved sites were identified that indicate acquired mutation during evolution. The selected pqq genes that appeared within an operon system sustain a specified order viz. pqqABCDE for both positive and negative strands. The nucleotide composition of the encoding genes displayed higher content of GCs at different positions of the codons and has also been properly reflected in relative synonymous codon usage (RSCU) values of the codons with few exceptions. The correspondence analysis (COA) based on RSCU proclaimed that the pqqB genes prefer A/U-ending codons over G/C, while for the pqqE gene, G/C-ending codons are comparatively more preferable (except CGU). Mutational pressure contributes to shaping the codon usage pattern for the selected pqq genes evinced from the COAs, while the ENc and neutrality plot gives attestation of natural selection. The higher values of CAI indicate the gene adaptability and codon usage bias. These comprehensive computational studies can be beneficial for further research in molecular phylogenetics, genomics, and proteomics and to better understand the evolutionary dynamics of PQQ.

“…Among these soil microorganisms, plant growth promoting rhizobacteria (PGPR) was initially described as; soil bacteria that located into roots of plants and they have fruitful features when inoculation onto seed and improve to plant growth by Kloepper and Schroth (1978). Therefore, researchers have been attracted attention to microorganisms based fertilizers instead of chemical fertilizers because of their high cost and detrimental impacts on sustainable agricultural applications in past decades (Adesemoye et al, 2009;Beneduzi et al, 2012;Alaylar et al, 2019;Ferreira et al, 2019;Alaylar et al, 2020a). Furthermore; they have been identified and reported PGPR bacteria including; Alcaligens, Arthobacter, Azospirillum, Azotobacter, Bacillus, Burkholderia, Enterobacter, Klebsiella, Pseudomonas, Rhizobium and Serratia (Egamberdieava, 2015;Afzal et al, 2017;Ferreira et al, 2019).…”

Plant growth promoting rhizobacteria (PGPR) have critical role in promoting plant growth and health with various mechanisms. Production of indole acetic acid (IAA) and 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity are well-known plant growth promoting (PGP) properties. In the current study; A total of 48 morphologically distinct bacterial colonies were chosen during the isolation of bacteria from various rhizospheric wheat, maize and sainfoin soil samples from agricultural areas in Ağrı-Turkey. The bacteria were isolated from soil samples utilizing by culture-dependent techniques. Then, the strains were visualised for PGP activities such as production acetic acid IAA and ACC deaminase activity. The 16S rRNA sequence similarity of potential PGPR rhizospheric strains demonstrated that strains belong to species Bacillus, Pseudomonas, Microbacterium, Pseudarthrobacter, Arthrobacter and Enterobacter. Totally, 11 of 48 isolates exhibited highly IAA producing and ACC deaminase activity. These results show that IAA producing and ACC deaminase activity of local potential PGPR strains isolated from soil rhizospheric which can appropriate for sustainable agricultural applications in Ağrı province.
