Physiological analyses of Telluria reveal many features that are consistent with traditional copiotrophic rhizosphere bacteria (Spiegel et al, 1991;Bowman et al, 1993;Anzai et al, 2000).

“…These taxa included a clade of organisms closely related to the genus Telluria, within the family Oxalobacteraceae (Betaproteobacteria) and bacteria from the genus Chryseobacterium (Bacteroidetes) (Green et al, 2006). Both are common to soil environments, and are aerobic, heterotrophic organisms (Kwok et al, 1987;Spiegel et al, 1991;Bowman et al, 1993;Bernardet et al, 2005). However, isolated members of the genus Telluria are flagellated and have chitinolytic, proteolytic and collagenolytic activity (Spiegel et al, 1991;Bowman et al, 1993), while Chryseobacterium are non-motile, heterotrophic organisms, frequently found in composted materials and other organic-rich environments (Kwok et al, 1987;Bernardet et al, 2005;Green et al, 2004Green et al, , 2006.…”

In this study, we investigated these taxa more closely to characterize the interaction of the rhizosphere effect and the influence of compost amendment as it varied between these seed-and root-colonizing microorganisms.…”

Contrasting patterns of seed and root colonization by bacteria from the genus Chryseobacterium and from the family Oxalobacteraceae

Microbial colonization of plant seeds and roots is a highly complex process in which soil and plant type can influence the composition of the root-associated and rhizosphere microbial communities. Amendment of compost, a common agricultural technique, introduces exogenous nutrients and microorganisms to the soil-plant environment, and can further influence microbial community composition in the plant environment. Although compost amendments can strongly influence soil and rhizosphere microbial communities, there is evidence that with increasing proximity to the root, plant influences predominate over soil effects. We hypothesized that the 'rhizosphere effect' observed with proximity to plant surfaces does not act equally on all microorganisms. To explore this issue, we examined two bacterial taxa that reproducibly colonized seed and root surfaces in an experiment examining the influence of compost amendment on plant-associated bacterial communities. Population-specific analyses revealed striking differences in the ecology of bacteria from the genus Chryseobacterium and the family Oxalobacteraceae in potting mix and plantassociated environments. Seed-and root-colonizing Oxalobacteraceae populations were highly sensitive to plant effects, and phylogenetic analyses of root-colonizing Oxalobacteraceae revealed the presence of root-associated populations that were highly similar, regardless of treatment, and differed from the potting mix populations detected at the same sampling points. Conversely, Chryseobacterium community composition was found to be essentially invariant within treatments, but was strongly influenced by compost amendment. This persistence and stable nature of the Chryseobacterium community composition demonstrates that rhizosphere selection is not the exclusive factor involved in determining the composition of the cucumber spermosphere and rhizosphere communities.

“…Many rhizobacteria can stimulate the plant growth and are termed as plant-growth promoting rhizobacteria or PGPR (Kloepper et al, 1980;reviewed in Ahemad and Kibret, 2013). Most frequently studied antagonistic rhizobacteria to affect the RKN are Bacillus subtilis, B. sphaericus and Pseudomonas fluorescens (Becker et al, 1988;Sikora, 1992;Tian et al, 2007 (Spiegel et al, 1991;Kloepper et al, 1992;Hallmann et al, 1995;Krechel et al, 2002;Oliveira et al, 2007;Son et al, 2009).…”

Root-knot nematodes (Meloidogyne spp.) are important pests of many cultivated plants. Recently, the most efficient chemical control products (e.g. methyl bromide) have now been restricted due to their toxic characteristics. Research on agents that work against root-knot nematodes and do not have a detrimental impact on the environment is becoming increasingly important. Advances in the last decades produced quite a number of biocontrol products that are already marketed. Some of the well-accepted commercial products contain bacteria Bacillus firmus and Pasteuria penetrans, and fungus Purpureocillium lilacinus. In this review we summarize the antagonistic activity of bacteria and fungi, with their advantages and limitations in biocontrol of root-knot nematodes.Key words: biological control, Meloidogyne spp., antagonisms, bacteria, fungi, commercial products IZVLEČEK BIOTIČNO ZATIRANJE OGORČIC KORENINSKIH ŠIŠK (Meloidogyne spp.): MIKROORGANIZMI PROTI ŠKODLJIVCEMOgorčice koreninskih šišk (Meloidogyne spp.) uvrščamo med pomembne škodljivce številnih kmetijskih rastlin. Najbolj učinkovita kemična sredstva za njihovo zatiranje so močno strupena, zato je njihova uporaba močno omejena ali celo prepovedana (npr. metil bromid). Razvoj na področju pripravkov za zatiranje ogorčic koreninskih šišk z okoljsko sprejemljivimi lastnostmi se povečuje. Napredek v zadnjih desetletjih je viden v večjem številu biotičnih pripravkov, mnogi med njimi se danes že tržijo. Aktivne snovi v uveljavljenih biotičnih sredstvih sta bakteriji Bacillus firmus in Pasteuria penetrans ter gliva Purpureocillium lilacinus. V članku je predstavljen pregled zaviralnih mehanizmov delovanja bakterij in gliv, prav tako omenjamo največje prednosti in slabosti njihove uporabe v biotičnem zatiranju ogorčic koreninskih šišk.Ključne besede: biotično varstvo rastlin, Meloidogyne spp., antagonizem, bakterije, glive, tržni pripravki

New nematode control measures are required due to the likely removal of effective nematicides from the market because of increasing concerns of possible effects on human health and the environment. Biological control, organic and inorganic soil amendments, naturally occurring nematicides, induced resistance, interruption of host recognition and transgenic plants will be a part of integrated management of plant-parasitic nematodes in the near future. The paper reports work carried out in Israel on these topics.
