To improve plant regeneration efficiency, the previous strategies focused on genotype screening, optimization on media components, and combination of plant growth regulators, while paying little attention to the significant impact of environmental stress on plant regeneration. This paper summarizes the recent research progress on different stress-induced effects on plant regeneration during tissue culture in vitro, including oxidative stress, osmotic stress, wounding, and cold stress. The oxidative stress plays a dual role in the plant regeneration process, i.e., induction of relevant stress antioxidant enzymes synthesis contributing to plant regeneration positively and changes on cell membrane permeability caused by oxidative stress leading to cell death negatively. The short-term osmotic stress significantly promotes the plant regeneration potential. Wounding has a positive effect on somatic embryogenesis by activating the relevant gene expression. The effect of temperature on the development of plant embryonic cells depends on the plant developmental stage and treatment intensity, and moderate temperature pretreatment can induce more embryonic calli. Therefore, appropriate stress pretreatment on explants used for tissue culture may contribute to the formation of embryogenic calli greatly, and may ultimately help to improve plant regeneration capacity during tissue culture in vitro., authors=SHE Maoyun¹, YIN Guixiang¹, DU Lipu², ZHANG Pingzhi¹, YE Xingguo², authorsList=SHE Maoyun, YIN Guixiang, DU Lipu, ZHANG Pingzhi, YE Xingguo, authorCompany=1.
