Cinnamomun bodinieri is an evergreen tree species and oil tree species of Cinnamomun genus in Lauraceae. It is mainly distributed in Yunnan, Guizhou, western Hunan, eastern Sichuan, Hubei and other regions in China. It likes acidic and slightly acidic soil and is vulnerable to the impact of saline and alkaline cultivation environment in the process of seedling breeding and green cultivation, resulting in poor growth and even death. It is necessary to study the mechanism of the root system of Cinnamomum monnieri adapting to alkali stress, In order to analyze the pathways and regulatory networks of monkeycamphor tree in response to alkali stress, and provide important gene resources for the cultivation of new varieties of monkeycamphor tree resistant to alkali stress.
