Low temperature generally inhibits development and/or growth of plants. Thus, winter appears to be a period that most plants endure and wait patiently until spring comes. However, besides predicting the arrival of spring, plants also engage in various activities during the winter. For example, plants induce the flowering process by sensing the prolonged winter cold (vernalization). Evergreen species can adjust the foliar photosynthetic property to chilling temperature and induce stress tolerance for maintaining their productive organs during winter. Moreover, plants also prepare for reproduction by suppressing leaf senescence and using them as storage organs. This symposium will focus on plant seasonality and responses to low temperatures. We will invite speakers who conduct research from different themes and perspectives, and discuss the dynamic ecology of plants in winter.
