   3.5.99.7 | physiological function |
1-aminocyclopropane-1-carboxylate (ACC) deaminase promotes plant growth by sequestering and cleaving the ethylene precursor ACC to 2-oxobutyrate and ammonium. Many plant growth promoting rhizobacteria producing 1-aminocyclopropane-1-carboxylate (ACC) deaminase as a source of nitrogen has an eminent role in plant nutrition |

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.

| 3.5.99.7 | physiological function |
ACC deaminase breaks down ACC, the direct precursor of ethylene biosynthesis in all higher plants, into ammonia and 2-oxobutyrate and, as a result, reduces stress ethylene levels in plants caused by a wide range of biotic and abiotic stresses. ACC deaminase from strain D3 can inhibit crown gall development induced by Agrobacterium tumefaciens strain C58 and can partially protect plants from this disease. Under gnotobiotic conditions, wild-type strain D3 is able to promote plant root elongation |

| 3.5.99.7 | physiological function |
ACC deaminase cleaves the ethylene precursor 1-aminocyclopropane-1-carboxylate into 2-oxobutanoate and ammonia. The decreased level of ethylene allows the plant to be more resistant to a wide environmental stress including plant pathogens |

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. |

comparative analysis of 1-aminocyclopropane-1-carboxylate (ACC) deaminase in selected plant growth promoting rhizobacteria (PGPR). The sequence and phylogenetic analysis of ACCD producing PGPR species represents the common conserved domain belonging to the tryptophan synthase beta subunit-like PLP-dependent enzymes superfamily and closely related to each other. The predicted homology models of ACCD of PGPR have similar protein structure with similar folds often share similar function. This analysis represents the evolutionary conservation and same biochemical function of ACCD producing plant growth-promoting rhizobacteria |

compared with the wild-type A1501, the acdS mutant A1815 is more sensitive to the environmental stresses of salt and heavy metal shock. The survival rate of A1815 is lowered by 1-2 orders of magnitude compared with the wild-type when exposed to 1.0 M NaCl treatment for 3 h and by 2-3 orders of magnitude when exposed to 13.2 mM NiCl2 for 3 h |
