The proper timing of developmental processes is essential for plant survival in seasonal environments as well as for crop yield. Germination, tuber formation, leaf abscission and flowering should occur at the appropriate time of year. The onset of these respective developmental programs is triggered by a change in daylength (a photoperiod). Short-day plants remain vegetative until they perceive a photoperiod shorter than a certain limit, whereas long day plants flower when a day is long enough. The availability of genetic resources and rapidly growing DNA sequence information led to focused research on a few model species, such as Arabidopsis thaliana, while setting aside research on many interesting plants. Chenopodium is an example of a neglected genus which was the favorite object of research of flowering since as early as 1940. This review summarizes the current status of the physiological and molecular knowledge of floral induction in Chenopodium.
