Cellulose synthesis genes CESA6 and CSI1 are important for salt stress tolerance in Arabidopsis

Soil salinity is a widespread abiotic stress constraint threatening agricultural production, as it severely inhibits growth and development of crops. Several salt stress signaling pathways have been discovered in the model plant Arabidopsis thaliana, which include components for sensing the stress, transmitting the signal and regulating the downstream genes （Deinlein et al. 2o14; Julkowska and Testerink 2015）. In nature, plant roots directly encounter heterogeneous soils and therefore their responses to saline environments require dynamic changes in growth, a process in which plant cell walls play important roles （Tenhaken 2o15）. However, the molecular mechanisms underlying cell wall remodeling under stress conditions are still unclear.
