Abstract

Bacillus safensis strain VK was isolated from the rhizosphere of a cumin plant growing in the saline desert of Radhanpar, Gujarat, India. Here, we provide the 3.68-Mb draft genome sequence of B. safensis VK, which might provide information about the salt tolerance and genes encoding enzymes for the strain’s plant growth-promoting potential.

On the rocks: the microbiology of Antarctic Dry Valley soils.

S. Craig Cary, Ian McDonald, John E. Barrett … (2010)

The arid soils of the Antarctic Dry Valleys constitute some of the oldest, coldest, driest and most oligotrophic soils on Earth. Early studies suggested that the Dry Valley soils contained, at best, very low levels of viable microbiota. However, recent applications of molecular methods have revealed a dramatically contrasting picture - a very wide diversity of microbial taxa, many of which are uncultured and taxonomically unique, and a community that seems to be structured solely by abiotic processes. Here we review our understanding of these extreme Antarctic terrestrial microbial communities, with particular emphasis on the factors that are involved in their development, distribution and maintenance in these cold desert environments.

Root colonization of different plants by plant-growth-promoting Rhizobium leguminosarum bv. trifolii R39 studied with monospecific polyclonal antisera.

B. Assmus, Jessica A. Hartmann, W Wiehe … (1997)

Monospecific polyclonal antisera raised against Rhizobium leguminosarum bv. trifolii R39, a bacterium which was isolated originally from red clover nodules, were used to study the colonization of roots of leguminous and nonleguminous plants (Pisum sativum, Lupinus albus, Triticúm aestivum, and Zea mays) after inoculation. Eight weeks after inoculation of soil-grown plants, between 0.1 and 1% of the total bacterial population in the rhizospheres of all inoculated plants were identified as R. leguminosarum bv. trifolii R39. To characterize the associative colonization of the nonleguminous plants by R.leguminosarum bv. trifolii R39 in more detail, a time course study was performed with inoculated roots of Z. mays. R. leguminosarum bv. trifolii R39 was found almost exclusively in the rhizosphere soil and on the rhizoplane 4 weeks after inoculation. Colonization of inner root tissues was detected only occasionally at this time. During the process of attachment of R. leguminosarum bv. trifolii R39 to the rhizoplane, bacterial lipopolysaccharides were overexpressed, and this may be important for plant-microbe interaction. Fourteen weeks after inoculation, microcolonies of R. leguminosarum bv. trifolii R39 were detected in lysed cells of the root cortex as well as in intracellular space of central root cylinder cells. At the beginning of flowering (18 weeks after inoculation), the number of R. leguminosarum bv. trifolii R39 organisms decreased in the rhizosphere soil, rhizoplane, and inner root tissue.
