Environmental Signal-Dependent Regulation of Flowering Time in Rice.

ABSTRACT: The transition from the vegetative to the reproductive stage of growth is a critical event in the lifecycle of a plant and is required for the plant's reproductive success. Flowering time is tightly regulated by an internal time-keeping system and external light conditions, including photoperiod, light quality, and light quantity. Other environmental factors, such as drought and temperature, also participate in the regulation of flowering time. Thus, flexibility in flowering time in response to environmental factors is required for the successful adaptation of plants to the environment. In this review, we summarize our current understanding of the molecular mechanisms by which internal and environmental signals are integrated to regulate flowering time in Arabidopsis thaliana and rice (Oryza sativa).
