Integration of photoperiod with physiological and environmental signals in plants

Integration of photoperiod with physiological and environmental signals in plants

Project Summary

In plants, the day length-dependent signaling pathway (photoperiod) controls important developmental processes such as flowering. The floral transition is a crucial decision for a plant as it compromises the success of the offspring and therefore, the yield of those crops that sustain great part of human nutrition. The photoperiod pathway is intertwined with other routes controlling environmental signals such as temperature or nutrient availability in a complex cross-communication that confers great plasticity to plant physiology and assures that the decision to flower takes place in the optimal time of the year. For this reason, environmental stresses such as drought, incorrect fertilization or the exposure to extreme temperatures could drastically decrease the flowering response and crop yield.
