Advances of Plant Circadian Clock Response to Light and Temperature Signals
摘要
Abstract
With the sharp change of the global climate,the ecological environment for plant is becoming increasingly harsh,therefore the molecular mechanisms underlying how circadian synergistically interacts with light or temperature receptors to transmit environmental signals and rhythmically regulate various growth and development process received widespread attention.As an endogenous timer of plants,the core oscillator of circadian clock is composed of multiple coupled transcriptional-translational feedback loops(TTFL),and it is modified from transcription,post-transcription,translation,post-translation to epigenetic levels.These multi-precise regulatory mechanisms ensure that the circadian clock can be synchronized and reset by external signals,so that the endogenous rhythm matches with external cycles,thereby endowing plants with the ability to optimize resource utilization and tend towards the optimal growth,which also has an important significance for guiding the genetic improvement and domestication of crops.In this review,we summa-rized the multi-level of regulatory mechanisms of core oscillator as well as the molecular function of circadian homologous genes in crops,thoroughly described the interaction network between the circadian clock and the light and temperature signal pathways and give prospects for molecular breeding based on the opinion,which provides new ideas for expanding the environmental adaptability and optimizing agronomic traits of crops.关键词
