Abstract: With the development of urbanization, the concentration of tropospheric ozone has been considerably increased during the past several decades, and its phytotoxicity has attracted serious attention as a widespread pollution problem. As a highly oxidative pollutant, ozone affects terrestrial plants in a variety of ways. It may negatively affect plant growth by causing morphological and physiological damage under ozone stress. Meanwhile, the impact of ozone on plants is greatly affected by atmospheric, soil and/or light conditions. Nowadays, global climate change and the normalization of extreme climate have significantly increased the opportunity of the interactions of ozone with many other environmental factors. As a result, the conditions in the experiments with consideration of the interactions of ozone and other environmental factors are much closer to natural environmental condition. The effects of interactions of ozone and these environmental factors are quite complicated, and mostly depend on plant species, ozone concentration, time, plant sensitivity to these environmental factors and the specific climate conditions. In this paper, the effects of interactions of ozone with carbon dioxide, sulfur dioxide, acid rain, nitrogen, drought, light or ultravioletB radiation were summarized and the interaction mechanism of ozone with other environmental factors was discussed. The hotspots for future study in this area should be the interactions of ozone with other environmental factors on the underground part and rhizosphere of plants, and the interplay mechanism of their roots, root functional changes and rhizosphere processes, the interactions of ozone with other environmental factors on various forests under different climatic conditions, the interaction of ozone with climate, air pollutants, heavy metal pollutants or stress such as low temperature on plants. In this paper, several patterns of biological evolution under stresses were figured out, to provide references for reasonable selection of ozoneresistant plants. It is of great significance to improving the ecological environment.
