Phycologists of the Botanical Society of Germany have selected Chlamydomonas reinhardtii as alga of the year 2014. This unicellular green alga is distributed throughout the world. It is able to sense its light environment, is a fast swimmer and is highly appreciated by algal and plant researchers as well as medical scientists as a model organism. The tiny alga has become an ideal organism for studying a variety of biological questions including a specific diurnal behavior which is triggered by an endogenous clock. Its intriguing features include its way of light perception using a primitive visual system and the transfer of the information to motile cilia; and it can protect itself from bursting by discharging excessive water. Chlamydomonas even provides the basis for the establishment of novel scientific areas in neurobiology and medicine, such as optogenetics where genetically modified cells are applied as ‘light switches’.

Members of the Phycology Section (Algology) (www.dbg-phykologie.de/en.html">www.dbg-phykologie.de/en.html) conduct research on algae and investigate, amongst others, taxonomical, ecological, physiological and molecular topics on macro- and microalgae. The Section promotes algal research and supports young scientists. The Section is one of five subject-specific Sections of the German Society for Plant Sciences (Deutsche Botanische Gesellschaft, DBG, www.deutsche-botanische-gesellschaft.de/en.html">www.deutsche-botanische-gesellschaft.de/en.html).
