Charles Darwin, like others before him, collected aeolian dust over the Atlantic Ocean and sent it to Christian Gottfried Ehrenberg in Berlin. Ehrenberg's collection is now housed in the Museum of Natural History and contains specimens that were gathered at the onset of the Industrial Revolution. Geochemical analyses of this resource indicated that dust collected over the Atlantic in 1838 origi...
A field experiment was conducted during kharif 2019 at Research Farm, Guru Kashi University, Talwandi Sabo, Bathinda (Punjab) to check the effect of rhizobium inoculation in relation with nitrogen levels on performance green gram. The trial laid split plot design two viz., 0 and 350 g ha-1 main four kg ha -1, 6 ha-1, 12 18 sub plot. Rhizobium seed significantly increased plant growth parameters...
Rhizobium spp. show chemotaxis to plant root exudates. Both legumes and non-legume root exudates attract the different rhizobia studied. However, the bacteria show a differential response in that they are attracted to the root exudates of some plants and show no attraction toward others. An example of negative chemotaxis was also observed. The trefoil strain of Rhizobium shows chemotaxis which ...
Concatenated sequence analysis with 16S rRNA, rpoB and fusA genes identified a bacterial strain (IRBG74) isolated from root nodules of the aquatic legume Sesbania cannabina as a close relative of the plant pathogen Rhizobium radiobacter (syn. Agrobacterium tumefaciens). However, DNA:DNA hybridization with R. radiobacter, R. rubi, R. vitis and R. huautlense gave only 44%, 5%, 8% and 8% similarit...
How good and how pleasant it is for organisms to dwell together in unity! And, probably, how common it is in the biological world. This review concerns a dramatic association, one of the few that has been studied in detail: the nitrogen fixing symbiosis between certain plants and microbes Rhizobium bacteria stimulate leguminous plants to develop root nodules, which the bacteria infect and inhab...
بررسی اکولوژیکی ازتوباکتر در دو منطقه مرتعی آذربایجان و اثر تلقیح آن روی رشد و تغذیه معدنی گیاه گندم
A great number of studies have been conducted on the role of Azotobacter - a free living N2-fixer - in agricultural soils, but our information is lacking on the importance of Azotobacter in pasture soils. This research was conducted to study the relationship between ecological and edaphical factors with the population of the bacteria in soil. Soil samples were taken from two sites in Azarbaidja...

The interactions of Meloidogyne javanica, Rotylenchulus reniformis, and Rhizobium sp. on cowpea seedlings were investigated. Upon simultaneous inoculation with the two nematode species, M. javanica invaded first but did not affect root invasion by R. reniformis. M. javanica populations increased less in competition with R. reniformis than when present alone. Preinvasion by R. renilormis signifi...
