Protein Variants

Protein Variants Comment Organism
additional information acdS gene deletion mutagenesis, Sinorhizobium sp. BL3-enhancing ACC deaminase activity (BL3+) and defective mutant (BL3-) strains are constructed in order to investigate the effects of this enzyme on symbiosis and nodule senescence. Modulation competitiveness is weaker in BL3- than in the wild-type, but is stronger in BL3+. The inoculation of BL3- into mung bean results in less plant growth, a lower nodule dry weight, and smaller nodule number than those in the wild-type, whereas the inoculation of BL3+ has no marked effects Sinorhizobium sp. BL3

physiological function Sinorhizobium sp. BL3 forms symbiotic interactions with mung bean (Vigna radiata cv. SUT1) and contains lrpL-acdS genes, which encode the 1-aminocyclopropane-1-carboxylate (ACC) deaminase enzyme that cleaves ACC, a precursor of plant ethylene synthesis. Detection of ACC deaminase expression by RT-PCR of acdS, and ACC deaminase activity from nodules of mung bean (Vigna radiata cv. SUT1) on the 3rd, 5th, and 7th week after the inoculation with BL3, BL3+, and BL3-. Requirement of ACC deaminase activity in Sinorhizobium sp. BL3 for nodulation competitiveness in mung bean. ACC deaminase activities direct the changing of biochemical molecules Sinorhizobium sp. BL3
