The ability for plants to understand their changing environment throughout the seasons is an essential key for the species survival. For annual plants, understanding their environmental influences is especially important as they only have one chance to induce flowering and the window of opportunity to give their offspring the greatest chance of success is small.
In a paper by Sibum Sung and Richard M Amasino, the processes behind the flowering of Arabidopsis thaliana are recorded with particular interest in the initiation and processes behind the vernalization pathway. The vernalization pathway is solely governed by environmental conditions although it is shown to be the main driver behind all genetic repression and expression. Many molecular groups in Arabidopsis only become active after a prolonged period of cold. Sung et al (2004) describe vernalization differently to many other papers such as Amasino (2003). It is shown that vernalization isn’t the event of flowering after winter, but rather the plant acquiring the ability to do so through prolonged cold exposure.
