Phytohormones, including ethylene and cytokinin, regulate multiple aspects of plant growth and development and responses to environmental stress.However, the exact roles of ethyleneand cytokinin in response to freezing stress remain unclear.Here, we show that ethylene insensitive mutants, including etr1-1, ein4-1, ein2-5, ein3-1 and ein3 eil1, displayed enhanced freezing tolerance.
