“…According to a report by Aarab et al (2015) E. ludwigii isolated rhizospheric soils of rice demonstrated IAA production. It was also shown by previous studies; rhizospheric bacteria from soil samples have capability to fix atmospheric nitrogen, phosphate solubilization, synthesing siderophores, ACC deaminase activity and type of phytohormones such as auxins for provide it to plants as a plant growth property (Alaylar et al, 2018;Ferchichi et al, 2019). IAA production is one of the most effective PGP mechanism (Pawlik et al, 2017 (Phetcharat and Duangpaeng 2012;Vinayarani and Prakash 2018).…”

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.

“…For example, endophytes associated with Monarda citriodora , which showed antagonistic activity against Fusarium oxysporum , F. redolens proved biocontrol potential [38] . Several basic mechanisms underlying plant beneficial effects were reported in the literature, including the production of phytohormones, fungi cell wall degrading enzymes, hydrogen cyanide (HCN) production and ACC-deaminase [71] – [73] . Ten out of sixteen bacterial strains produced at least one of four checked fungal cell wall degrading enzymes, i.e., chitinase, protease, ß-1,3-glucanase, and lipase.…”

<abstract> <p>Endophytes colonizing plant tissue play an essential role in plant growth, development, stress tolerance and plant protection from soil-borne diseases. In this study, we report the diversity of cultivable endophytic bacteria associated with marigold (<italic>Calendula officinalis</italic> L.) by using 16S rRNA gene analysis and their plant beneficial properties. A total of 42 bacterial isolates were obtained from plant tissues of marigold. They belonged to the genera <italic>Pantoea, Enterobacter, Pseudomonas, Achromobacter, Xanthomonas, Rathayibacter, Agrobacterium, Pseudoxanthomonas</italic>, and <italic>Beijerinckia</italic>. Among the bacterial strains, <italic>P. kilonensis</italic> FRT12, and <italic>P. rhizosphaerae</italic> FST5 showed moderate or vigorous inhibition against three tested plant pathogenic fungi, <italic>F. culmorum, F. solani</italic> and <italic>R. solani</italic>. They also demonstrated the capability to produce hydrolytic enzymes and indole-3-acetic acid (IAA). Five out of 16 isolates significantly stimulated shoot and root growth of marigold in a pot experiment. The present study reveals that more than half of the bacterial isolates associated with marigold (<italic>C. officinalis</italic> L.) provided antifungal activity against one or more plant pathogenic fungi. Our findings suggest that medicinal plants with antimicrobial activity could be a source for selecting microbes with antagonistic activity against fungal plant pathogens or with plant growth stimulating potential. These isolates might be considered as promising candidates for the improvement of plant health.</p> </abstract>

“…We confirmed that Xanthomonadaceae OTUs were significantly more abundant in rhizosheath supplied with struvite and organic fertilizer. Endophytic Xanthomonas ribotypes have been recorded in L. angustifolius nodules (Ferchichi et al, 2019). PGPRs such as Sphingomonas and Burkholderia (Compant et al, 2005;Khan et al, 2014Khan et al, , 2017 and Phenylobacterium (Lingens et al, 1985), a Gram-negative bacterium that degrades xenobiotic compounds, were positively associated with pH when struvite was supplied.…”
