Fluctuations of soil bacterial communities under potato cropping
It is important to understand the underlying factors that lead to shifts in soil microbial communities, not simply for the characterization of these complex biotic systems, but also to understand the impact that changes in microbial community composition may have on terrestrial ecosystems. In this study, the impact of genetically different potato (Solanum tuberosum) plants growing in arable soi...
متن کاملDynamic Succession of Soil Bacterial Community during Continuous Cropping of Peanut (Arachis hypogaea L.)
Plant health and soil fertility are affected by plant-microbial interactions in soils. Peanut is an important oil crop worldwide and shows considerable adaptability, but growth and yield are negatively affected by continuous cropping. In this study, 16S rRNA gene clone library analyses were used to study the succession of soil bacterial communities under continuous peanut cultivation. Six libra...
متن کاملThe Effect of Long-Term Continuous Cropping of Black Pepper on Soil Bacterial Communities as Determined by 454 Pyrosequencing
In the present study, 3 replanted black pepper orchards with continuously cropping histories for 10, 21, and 55 years in tropical China, were selected for investigating the effect of monoculture on soil physiochemical properties, enzyme activities, bacterial abundance, and bacterial community structures. Results showed long-term continuous cropping led to a significant decline in soil pH, organ...
متن کاملOrganic loading rates affect composition of soil-derived bacterial communities during continuous, fermentative biohydrogen production
Bacterial community composition during steady-state, fermentative H2 production was compared across a range of organic loading rates (OLRs) of 0.5–19 g COD l 1 h 1 in a 2-l continuous flow reactor at 30 C. The varied OLRs were achieved with glucose concentrations of 2.5–10 g l 1 and hydraulic retention times of 1–10 h. The synthetic wastewater feed was amended with L-cysteine and maintained at ...
متن کاملNormal operating range of bacterial communities in soil used for potato cropping.
In this study, the impacts of six potato (Solanum tuberosum) cultivars with different tuber starch allocations (including one genetically modified [GM] line) on the bacterial communities in field soil were investigated across two growth seasons interspersed with 1 year of barley cultivation, using quantitative PCR, clone library, and PCR-denaturing gradient gel electrophoresis (DGGE) analyses. ...
