Abstrakt: The transition from the vegetative to the reproductive phase is a crucial event in plant development. The floral induction is tightly controlled at multiple levels. While physiological and anatomical studies of flowering have begun in the nineteenth century, the genetic basis of the floral induction remained concealed until the end of the twentieth century. The molecular regulatory pathways mediating the responses to environmental and endogenous cues were first revealed in the model plant Arabidopsis thaliana, later in Oryza sativa (rice), and other crops. Knowledge on flowering in wild species proceeded in much slower pace. Little research was devoted to the family Amaranthaceae, except for the agriculturally important sugar beet. Nowadays, this picture starts to change owing to the availability of genomic and transcriptomic resources in non-model organisms. This review outlines basic characteristics of the regulation of flowering in model plants and summarizes current knowledge on this topic in the genus Chenopodium and its relatives.
