Photoperiod-Dependent Mechanisms of Flowering Initiation in Arabidopsis thaliana L. and Zea mays L
2022
Shchennikova, A. V.
The domestication of plants involves their adaptation to different climatic conditions, including changes in photoperiod and temperature. Many genetic loci of domestication are orthologous in distant taxa. The main molecular genetic mechanisms of flowering have been described in detail in the model plant Arabidopsis thaliana L., which forms the basis for studying and building models of flowering of other plant species. The domestication and breeding of maize Zea mays L. has resulted in a wide variety of responses to day length in this species, while maintaining the basis of the genetic network that controls sensitivity to photoperiod. The review considers the features of the response to the photoperiod of maize plants in comparison with the model species Arabidopsis, including phenological genes for maize breeding, which were the target of selection in the process of Zea mays adaptation to new ecological and geographical conditions.
