Tulips are one of the iconic associations with the Netherlands. However, climate change is threatening the development of tulips. For this reason it is important to study how temperature is influencing genes that are involved in the flowering process. The majority of people enjoy a warm spring, but for tulips this can lead to a disaster. Due to the high temperature some tulip cultivars produce a flower inside the bulb already before harvesting, which leads to floral dehydration. We identified genes that are regulating the induction of flower development. These genes can be used as markers in the future to prevent this dehydration phenomenon. Secondly, we investigated what is happening at the metabolic and molecular level during storage and the winter period in the field. Even though the flower is already inside the bulb, it still needs a period of cold to be able to flower in spring.
