Many plants flower after winter (vernalization), including life forms with single (annuals) and multiple (perennials) flowering. In nature, vernalization provides an adaptation to local climates and in agriculture, it influences production of many crucifer crops (cabbage, daikon, wasabi and more). The central gene of vernalization and cold sensing components were studied in annuals but not in perennials. Understanding genetic control of perennial vernalization will allow introduction of perennial features into future crops, which, like all perennials, should survive unprotected in nature.
