Time required for tumor induction by Agrobacterium tumefaciens.
Cellulose-minus mutants of Agrobacterium tumefaciens retain virulence but can be removed from wound sites by washing with water. Washing of Bryophyllum diagremontiana leaves inoculated with a cellulose-minus mutant was used to determine the minimum time the bacteria must be present for tumor induction. This time was 4 to 8 h.
متن کاملSusceptibility of Agrobacterium tumefaciens Strains to Two Agrocin-Producing Agrobacterium Strains.
Sixty-five strains and isolates of Agrobacterium tumefaciens representing each of the known biotypes, were tested for in vitro and in vivo susceptibility to the agrocin-producing strains Agrobacterium radiobacter 84 and A. tumefaciens D286. No biotype 3 strain was susceptible to the effects of either of the agrocinogenic strains in vitro. On datura and tobacco, the best inhibition of tumor form...
متن کاملCharacterization of Agrobacterium Tumefaciens Strains Isolated from Root Nodules of Vigna Trilobata (l) Verdc. Cultivars
Root nodulating bacteria was isolated from root nodules of Vigna trilobata (L) Verdc. Plants raised in the soils were collected from five geographically different areas in Andhra Pradesh, India. The bacteria was identified as Agrobacterium tumefaciens strains by 16S rDNA analysis. Except A. tumefaciens MRR 102, all the strains produced round shape and white coloured colonies with lot of mucilag...
متن کاملInfluence of different strains of Agrobacterium rhizogenes, culture medium, age and type of explant on hairy root induction in Echinacea angustifolia
Hairy roots culture is a potential system for secondary metabolite production in medicinal plants. In this research, hairy root induction in Echinacea angustifolia was established using Agrobacterium rhizogenes. The effects of dif-ferent A. rhizogenes strains (AR15834, A4, K599 and MSU440) in two solid growth regula-tor-free culture media, half strength MS salts with B5 vitamins and WPM, were e...
متن کاملInduction of D-aldohexoside:cytochrome c oxidoreductase in Agrobacterium tumefaciens.
D-Aldohexopyranoside:cytochrome c oxidoreductase (ACO) was strongly induced by cellobiose, alpha-methylglucoside, beta-methylglucoside, kojibiose, and sophorose. Induction was rapid, and ACO was readily detectable within 10 min after addition of cellobiose as inducer. Although not measurable for 30 to 40 min after addition of inducer, once started, the rate of induction with alpha-methylglucosi...
