acetosyringone

06/01/2022 - "The transformation efficiency was significantly improved by optimizing the pre-culture of explants, co-cultivation duration, bacterial density and infection time, and acetosyringone concentration. "
04/10/2023 - "In the Agrobacterium transient expression system, the highest transformation rate was obtained at the original Agrobacterium concentration of OD600 0.4, infiltration concentration of OD600 0.6, infection for 20 min, co-culture for 3 days, and acetosyringone concentration of 100 μmol·L-1. "
04/01/2023 - "Then the optimal transformation efficiency of the gus reporter gene was obtained by infection with Agrobacterium tumefaciens culture of OD600 = 0.5 for 30 min, followed by 3 days of co-cultivation with 300 μmol/L acetosyringone. "
09/25/2022 - "Furthermore, the addition of 100 µM acetosyringone was necessary for Agrobacterium infection. "
01/01/2022 - "The incubation of wounded sprouted seeds in 1.0 OD of agroculture containing repeat construct of MYMIV for 2-4 h without acetosyringone followed by sowing in soil showed maximum infection of MYMIV within 10-12 days on the first trifoliate leaf. "

10/27/2010 - "In the natural environment it is possible that Agrobacterium and fungi may encounter each other at plant wound sites, where acetosyringone would be present, raising the possibility of natural gene transfer from bacterium to fungus. "
07/01/1995 - "Mutagenesis of the vir region on the Ti plasmid of Agrobacterium tumefaciens revealed a new locus, virJ, that is induced by the plant-wound signal molecule, acetosyringone (AS). "
01/01/1991 - "tumefaciens to wound sites, where the higher acetosyringone concentrations lead to virA and virG-mediated induction of the vir-genes. "
01/01/1991 - "By interfacing with this system, the multifunctional products of two Ti-plasmid encoded genes, virA and virG, allow the sensing of specific wound phenolics such as acetosyringone. "
07/01/1987 - "The rate of transformation ranged from 55 to 63 percent when acetosyringone (AS), a natural wound response molecule, was added to an Agrobacterium tumefaciens culture prior to incubation with leaf segments. "

09/01/2010 - "The significant decrease of tumor size could be suppressed by the pre-activation of bacterial virulence, before inoculation, using acetosyringone a known vir inducer. "
08/31/1998 - "The virulence (vir) genes of Agrobacterium tumefaciens KU12, a Korean strain, were not induced by acetosyringone and the strain showed weak tumor forming ability and broad plant host ranges. "
07/01/1989 - "Upon incubation of Agrobacterium tumefaciens A348 with acetosyringone, the vir genes encoded by the Ti (tumor-inducing) plasmid are induced. "
09/01/1990 - "Most virulence (vir) genes of Agrobacterium tumefaciens that are required for the formation of crown gall tumors are expressed in response to such plant signal molecules as acetosyringone and lignin precursors. "
09/01/2010 - "Statistical correlations were established between tumor sizes, vir-inducing activities, O-methyltransferases proteins accumulations and the levels of various soluble phenolic compounds such as acetosyringone. "

05/01/1989 - "The virulence of the octopine strains was increased by coinfection with more virulent disarmed strains and by induction with acetosyringone. "

09/01/1988 - "In addition to being induced by acetosyringone, the virG promoter was partially induced by acidic growth conditions and by starvation for inorganic phosphate. "
