    Phase response curves reveal how biological clocks respond to stimuli applied during different circadian phases but can be costly to produce. Here Masuda et al. show that phase response curves for plants can be reconstructed by monitoring how a desynchronized population responds to a single stimulus.

    Glyphosate is the world’s most widely-used herbicide. Here, Belbin et al. show that plant responses to glyphosate, and therefore herbicide activity, depend on plant circadian rhythms suggesting that considering the time-of-day of application could lead to more efficient agrochemical use.

    The PIF4 transcription factor promotes adaptation to elevated temperature but is degraded under red light to trigger photomorphogenesis. Here Sun et al. show that the core circadian component CCA1 recruits SHB1 to sustain PIF4 expression after dawn to balance thermomorphogenesis and light responses.

    Circadian control of plant defence likely reflects plants’ ability to coordinate development and defense. Here, Zhang et al. show that LUX regulates stomatal defense  and SA/JA signaling, leading to broad-spectrum disease resistance, and that JA signaling can, in turn, regulate clock activity.

    Biological circadian rhythms maintain a period close to 24 h in coordination with the Earth’s fixed rotational period. Here Webb et al. discuss how external cues continuously adjust phase and period, viewing the oscillator as a dynamically-adjusted plastic system rather than tightly-coupled cogs in a mechanical clock.

    The plant circadian clock regulates numerous developmental processes such as seasonal growth and flowering time. Here Ritteret al. identify two transcription factors, FRS7 and FRS12, which interact to form a repressor complex that regulates clock output partially by controlling the expression of GIGANTEA and PIF4.

    TheArabidopsisCCA1 transcription factor is a core regulator of the circadian clock. Here, the authors show that the LWD1 protein, in complex with the TCP20 or TCP22 transcription factors, acts as a co-activator of CCA1 expression contributing to elevated CCA1 expression at dawn.

    Circadian rhythms allow plants to respond to diurnal fluctuations in the environment. Here Caldeira et al. find that circadian control of hydraulic conductance, aquaporin expression and leaf growth are entrained by oscillations of plant water status and promote water uptake in drought-stressed plants.
