Response of rhizosphere bacterial community in Taxus chinensis var.mairei to temperature changes

The rhizosphere bacterial communities of Taxus chinensis var.maire under a series of temperature of 5°C (T5), 15°C (T15), 25°C (T25), 35°C (T35) were assessed through high-throughput sequencing. Results showed that the activity of POD and SOD were increased and decreased with incubation temperature increasing. Taxus chinensis var.maire enriched specific bacterial taxa in rhizosphere under different temperature, and some taxa were significantly correlated the activity of POD and/or SOD. There results indicated that rhizosphere bacteria may play important role for Taxus chinensis var.maire in coping with temperature changes, and the management of rhizosphere bacteria in a potential way to increase the cold resistance of Taxus chinensis var.mairei, thus improve its growth under low temperature and enlarge its habitats.
