“…These findings suggest that phenotypic expression of A. rhizogenes in the form of hairy root initiation is strongly affected by A. rhizogenes strain, explant type as well as tissue-Agrobacterium interaction. Similar results have also been reported in Cucumis and pine tree when infected with A. rhizogenes strains (Katavic et al, 1991, Mihaljevic et al, 1996McAfee et al, 1993).…”

The virulence response of five wild type Agrobacterium tumefaciens (tumorigenic) strains and five wild type A. rhizogenes (oncogenic) strains was studied in cucumber (Cucumis sativus L.), cv. Spring Swallow. Several physical and chemical factors e.g. Agrobacterium strains, tissue type (stem and petiole tissues), light intensity, dark incubation, concentrations of acetosyringone (a phenolic compound) were tested. The virulent response of Agrobacteria was found to be depend on plant tissue type, Agrobacterium strain, tissue-Agrobacterium interaction and both chemical-physical factors. Specific light intensity, 2500-lux, as well as the acetosyringone concentration, 20-M, played important role in virulence response. Among the different strains, LBA 4404 and 15834 were highly virulent to cucumber compared to the other strains tested. A. tumefaciens strains A348 and A281 were failed to initiate crown galls in both stem and petiole tissues, however, in the presence of acetosyringone they produced crown galls. Similarly, A. rhizogenes strain A4 initiated hairy roots in the presence of acetosyringone. All developed crown galls and hairy roots showed an autonomous growth on a hormone free medium containing cefatoxime. Thus, enhancement of virulence response was not only dependent on Agrobacterium strains, but also on particular physical and chemical factors also play vital role.

“…As a genus, Agrobacterium can transfer DNA to a remarkably broad group of organisms including numerous dicot and monocot angiosperm species (12,68,262,341) and gymnosperms (198,206,215,228,307,357,371). In addition, Agrobacterium can transform fungi, including yeasts (32,33,260), ascomycetes (1,71), and basidiomycetes (71).…”

SUMMARY Agrobacterium tumefaciens and related Agrobacterium species have been known as plant pathogens since the beginning of the 20th century. However, only in the past two decades has the ability of Agrobacterium to transfer DNA to plant cells been harnessed for the purposes of plant genetic engineering. Since the initial reports in the early 1980s using Agrobacterium to generate transgenic plants, scientists have attempted to improve this “natural genetic engineer” for biotechnology purposes. Some of these modifications have resulted in extending the host range of the bacterium to economically important crop species. However, in most instances, major improvements involved alterations in plant tissue culture transformation and regeneration conditions rather than manipulation of bacterial or host genes. Agrobacterium-mediated plant transformation is a highly complex and evolved process involving genetic determinants of both the bacterium and the host plant cell. In this article, I review some of the basic biology concerned with Agrobacterium-mediated genetic transformation. Knowledge of fundamental biological principles embracing both the host and the pathogen have been and will continue to be key to extending the utility of Agrobacterium for genetic engineering purposes.

“…In the experiment conducted by Zydlik and Zydlik (2008) the EM-A preparation mixed with EM-5 increased the volume of the root system of the M.9 rootstock. Also, McAfee et al (1993) observed a higher percentage of rooted pine and larch cuttings after treatment with Agrobacterium rhizogenes. Similarly, Ercisli et al (2004) observed better root formation on hardwood stem cuttings of two roses after treatment with exogenous IBA and Agrobacterium rubi.…”

THE INFLUENCE OF TREATMENTS APPLIED TO COMMON NINEBARK (PHYSOCARPUS OPULIFOLIUS (L.) MAXIM.) 'DIABOLO' CUTTINGS ON THEIR ROOTING AND GROWTHWPŁYW KILKU SPOSOBÓW TRAKTOWANIA SADZONEK NA UKORZENIANIE I WZROST PĘCHERZNICY KALINOLISTNEJ (PHYSOCARPUS OPULIFOLIUS (L.) MAXIM.) ODMIANY 'DIABOLO' Abstract Background. As synthetic auxins are prohibited, it is necessary to conduct research to assess the suitability of other substances used for propagation of ornamental bushes to improve the rooting of cuttings and the growth of plants. The aim of the experiment was to compare the effectiveness of a mycorrhizal inoculum and effective microorganisms in the production of ninebark shrubs. Material and methods. Between 2010 and 2012 an experiment on Physocarpus opulifolius 'Diabolo' was conducted to assess how three different treatments applied to cuttings influenced their rooting and growth. Before hardwood cuttings were planted in a field, they had been treated with an endomycorrhizal inoculum, effective microorganisms and Ukorzeniacz AB Aqua. The diameter and length of the shoots were measured. The number of shoots was counted, the percentage of rooted cuttings was calculated and the fresh mass of the root system was weighed. Results. The mycorrhizal inoculum increased the percentage of rooted cuttings and gave the best results in the diameter and length of lateral shoots as well as the fresh mass of the root system of the bushes. The effective microorganisms (EM) resulted in the highest percentage of rooted cuttings and the largest number of lateral shoots. The EM preparation improved the diameter and fresh mass of the root system. The Ukorzeniacz AB Aqua improved the rooting of the cuttings and increased the diameter and fresh mass of the root system. Conclusions. The mycorrhizal inoculum improved the rooting of the cuttings and stimulated the growth of the shrubs. The effective microorganisms increased the percentage of rooted cuttings, as the Ukorzeniacz AB Aqua did, and improved the growth of the plants.Keywords: ninebark, propagation, hardwood cuttings, mycorrhizal inoculum, effective microorganisms (EM), Ukorzeniacz AB Aqua Świerczyński, S., Stachowiak, A., .
