   3.5.99.7 | physiological function |
effect of bacterial ACC deaminase overproduction on Medicago lupulina plants growth and nodulation, overview. The biomass production is significantly increased in the plants inoculated with Sinorhizobium meliloti overexpressing the Pseudomonas putida enzyme (pRKACC) or co-inoculated with wild-type Sinorhizobium meliloti and Pseudomonas putida UW4 in comparison with the plants inoculated with wild-type Sinorhizobium meliloti. The dry weight of aerial parts of plants inoculated with Sinorhizobium meliloti overexpressing the Pseudomonas putida enzyme (pRKACC) are enhanced by 31.6 % in the presence of 200 mg/kg Cu2+, and by 54.4 % in the presence of 400 mg/kg Cu2+, as compared with the plants inoculated with wild-type Sinorhizobium meliloti. The dry weight of roots is also significantly increased by 34.6 and 39.4 % in the pRKACC-strain inoculated plants treated with 200 and 400 mg/kg Cu2+. Similarly, a significant increase is also observed in the biomass production of plants co-inoculated with wild-type Sinorhizobium meliloti and Pseudomonas putida UW4 |

ACC deaminase producing plant growth promoting rhizobacteria (PGPR) are isolated from the rhizosphere of Triticum aestivum var. Lok-1 and identified using 16S rRNA gene sequence analysis. Isolates are evaluated for various direct and indirect plant growth promoting (PGP) traits. 38 ACC deaminase producing PGPR are isolated which belonged to 12 distinct genera and falling into four phyla gamma-proteobacteria, beta-proteobacteria, Flavobacteria and Firmicutes. Klebsiella sp. is the most abundant genera and followed by Enterobacter sp. |

1-aminocyclopropane-1-carboxylate deaminase (ACCD)-producing endophytic Streptomyces sp. GMKU 336 and its ACCD-deficient mutant are inoculated into Thai jasmine rice Khao Dok Mali 105 cultivar (Oryza sativa cv. KDML105) under salt stress (150 mM NaCl) conditions. The results clearly indicate that Streptomyces sp. GMKU 336 significantly increases plant growth, chlorophyll, proline, K+, Ca+, and water contents, but decreases ethylene, reactive oxygen species (ROS), Na+, and Na+/K+ ratio when compared to plants not inoculated and those inoculated with the ACCD-deficient mutant. Genes involved in the ethylene pathway, ACO1 and EREBP1, are significantly downregulated, while acdS encoding ACCD in Streptomyces sp. GMKU 336 is upregulated in vivo.

phylogenetic, chemotaxonomic, phenotypic and genomic characterisation indicates that the detected strains belong to a distinct genus and species of the order Oceanospirillales for which the names Pokkaliibacter gen.nov., and Pokkaliibacter plantistimulans sp. nov., are proposed with L1E11 / DSM 28732 / MCC 2992 as the type strain. The isolate is found in association with plants grown in brackish environments and possesses plant growth promotion traits such asACC deaminase, siderophore production and phosphate solubilisation. The type species of the genus is Pokkaliibacter plantistimulans |

| 3.5.99.7 | physiological function |
the phytostimulatory effects of the detetcted strain are checked on inoculated pokkali rice variety (Oryzsa sativa VTL-6). Initial treatment of VTL-6seeds with strain L1E11 does not have any negative effect on the seed germination. Increased root length and fresh weight in L1E11-treated seeds is observed as compared to non-treated pokkali seeds after 14 days of incubation. Strain L1E11 is able to promote rice growth. L1E11-treated rice plants are able to resist 200 mM NaCl stress better as compared to the uninoculated control plants. L1E11 can mediate growth and protect its host plant from saline stress by modulating the stress ethylene levels as like other ACCd producing plant beneficial rhizobacteria functions |
