亮点温度影响许多过程，包括开花、生物钟和生长。PIF4 控制对较高温度的许多反应。H2A。 Z 核小体控制环境温度转录组。植物暴露在每日和季节性的温度波动中。在“环境”温度范围内（拟南芥约为 12-27°C），温度差异对植物生长和发育、抗病途径和生物钟有很大影响，但不会激活温度胁迫途径。本次综述将讨论这种对无压力温度的发育感知和反应。最近的进展揭示了调节温度信号的关键因素。 bHLH 转录因子 PHYTOCHROME INTERACTING FACTOR4 (PIF4) 已被证明是拟南芥对高温的多种反应的枢纽，包括开花和下胚轴伸长。染色质状态的变化涉及将温度信号传递到转录组。确定温度感知的精确机制是该领域的一个令人兴奋的目标。
HighlightsTemperature influences many processes, including flowering, the circadian clock and growth.PIF4 controls many responses to warmer temperature.H2A. Z-nucleosomes control the ambient temperature transcriptome.Plants are exposed to daily and seasonal fluctuations in temperature. Within the ‘ambient’temperature range (about 12–27 C for Arabidopsis) temperature differences have large effects on plant growth and development, disease resistance pathways and the circadian clock without activating temperature stress pathways. It is this developmental sensing and response to non-stressful temperatures that will be covered in this review. Recent advances have revealed key players in mediating temperature signals. The bHLH transcription factor PHYTOCHROME INTERACTING FACTOR4 (PIF4) has been shown to be a hub for multiple responses to warmer temperature in Arabidopsis, including flowering and hypocotyl elongation. Changes in chromatin state are involved in transmitting temperature signals to the transcriptome. Determining the precise mechanisms of temperature perception represents an exciting goal for the field.
