Abstract: Temperature is one of the most essential factors which would affect the sexual reproduction in flowering plants. Temperature stress often leads to pollen abortion. Here， the effects of temperature stress on pollen development were summarized， including the most sensitive stage of pollen development to temperature stress， the change of tapetum， sugar metabolism and hormone levels caused by temperature stress. The effects of cold and heat stress on pollen development were also briefly compared. The progresses of molecular mechanism of pollen response to cold stress were simply summarized and six genes involved in pollen response to cold stress were emphatically introduced. Furthermore， the main problems in current researches and the key points in future studies were also proposed， in hope of providing reference for further revealing the molecular mechanisms of pollen response to temperature stress.
