متن کاملInteractive Effects of Copper on Alfalfa Growth, Soil Copper, and Soil Bacteria
Copper sulfate (CuSO4) foot baths are a management practice used by dairy farms in an effort to control hoof infections. As an unintended consequence, agricultural soils experience Cu accumulation when spent foot baths are disposed of in wastewater lagoons utilized for irrigation purposes. We investigated the effect of Cu applications (up to 1000 mg kg) to a Xeric Haplocalcid (Declo series) and...
متن کاملCultivation Effect of Chitinase-Transgenic Cotton on Functional Bacteria and Fungi in Rhizosphere and Bulk Soil
Background: In consideration for the increasing widespread use of genetically modified (GM) crops, one of the important issues for assessment is the effect of GM crops on soil microbial communities Objectives: In this study, T2 chitinase-transgenic cotton (line #57) and its non-transgenic line were investigated for bacterial and fungal dynamics...
متن کاملGermination of Salt Tolerant and Non - Tolerant Alfalfa in Nacl, Nan03, Kcl, Kno3, and Mannitol
Five cycles of germination NaC1 tolerant alfalfa and the source population, 'Mesa Sirsa', were germinated in four salt solutions (NaC1, NaNO3, KC1, and KNO3) and Mannitol to try to determine the general mechanism involved in seed germination salt tolerance. Average germination over all germplasm sources in NaC1, NaNO3, KC1, KNO3, and Mannitol were 44.80, 38.88, 36.24, 29.07, and 60.93 percent, ...
متن کاملScreening of rhizosphere and soil bacteria for transformability.
Natural transformation is assumed to be the most likely mechanism by which DNA from transgenic plants could be horizontally transferred to bacteria. In order to determine the occurrence of naturally transformable bacteria amongst bulk and rhizosphere soil bacteria, different transformation strategies were employed using either plasmid DNA (IncQ plasmids pSM1890 and pSM1885, conferring GFP, Sm(r...
