“…This type of association has a significant role in satisfying host nitrogen needs and improving soil fertility and plant growth. In addition to rhizobia, non-rhizobial species have been reported in the root nodules of L. corniculatus such as Paenibacillus kribbensis, Pseudomonas grimontii, and Bacillus subtilis (El-Batanony et al, 2020). Additionally, a wide variety of microbial groups exists in the rhizospheric zone of L. corniculatus, including Arthrobacter, Bacillus, and Pseudomonas (Borozan et al, 2019).…”

“…Despite their economic and ecological importance, relatively few studies (El-Batanony et al, 2020;Knežević et al, 2021;Das and Barik, 2022) have investigated the natural population of PGPR associated with the roots of L. corniculatus particularly in the Al-Ahsa region, which presents harsh conditions, such as drought, salinity, and elevated temperature. PGPR associated with the roots of L. corniculatus could reveal bacterial species that are previously unreported.…”

Significant food resource shortages are occurring worldwide. Plant growth-promoting rhizobacteria (PGPR) represent an ecofriendly and efficient approach for increasing soil fertility and plant productivity. The current study explored biostimulating traits of PGPR from the rhizosphere of Lotus corniculatus growing in the Al-Ahsa region. A bacterial isolate (LCK121) was obtained, characterized for phenotypic, and identified by 16S rRNA gene sequencing. In addition, its growth-stimulating effects on barley were investigated. The strain identity was confirmed via comparative analysis of the 16S rDNA sequences with Klebsiella oxytoca (99.3% similarity level). LCK121 exhibited multiple plant growth-promoting features, including indole-3-acetic acid (IAA) production (16.34 µg mL-1), 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity (1.35±0.02 µmol α-ketobutyrate mg−1 h−1), phosphate solubilization, and nitrogen fixation. Furthermore, in vitro inoculation of barley with LCK121 significantly increased the root and shoot dry weights. The results highlight the potential of LCK121 for developing green fertilizers for sustainable agriculture.
