All the selected isolates produced indole-3-acetic acid at the rate\n              of 9.2\u201333.7\u00a0mg\/ml. In addition, 13, 15, 12, and 16 were positive for phosphate\n              solubilization, siderephore, hydrogen cyanide, and ammonia production, respectively.\n              The results from a subsequent pot experiment indicated that PGPRs distinctly increased\n              sun flower shoot and root length, shoot and root fresh weight, as well as shoot and\n              root dry weight. Based on 16S rDNA sequences and biochemical and physiological\n              characteristics, 20 PGPRs were identified as <jats:italic>Pseudomonas\n                fluorescens<\/jats:italic> (five isolates), <jats:italic>Pseudomonas\n                aeruginosa<\/jats:italic> (four isolates), <jats:italic>Pseudomonas\n                geniculata<\/jats:italic> (one isolate), <jats:italic>Bacillus subtilis<\/jats:italic>\n              (four isolates), <jats:italic>Bacillus pumilus<\/jats:italic> (two isolates),\n                <jats:italic>Stenotrophomonas maltophilia<\/jats:italic> (two isolates), and\n                <jats:italic>Brevibacterium frigoritolerans<\/jats:italic> (two isolates). In\n              rep-PCR, PGPR isolates were differentiated into seven clusters (A\u2013G) at 65% similarity\n              level.
