Popis: | In the rhizosphere, the soil bacteria and the plants are closely related, with the plant-associated microbiota playing an important role in promoting plant growth under both normal and stress conditions. In this study, the cultivable bacteria in the sugarcane rhizosphere under different levels of drought stress were characterized and screened for plant growth activities. The results suggested that the microbial community associated with the sugarcane rhizosphere was strongly affected by drought, but some important genera of bacteria such as Arthrobacter, Pseudomonas, Microbacterium, and Bacillus remained present during the entire experiment, indicating the adaptability of these organisms and their importance in the rhizosphere community. Many isolates exhibited positive results for one or more plant growth activity, and they were also capable of growing under simulated drought stress, suggesting that the microorganisms isolated from the sugarcane rhizosphere could be explored for uses such as biofertilizers or biocontrol agents in agriculture. |
