2025年2月7日 · The deterministic tomato circadian clock model in warm temperatures mainly aimed to construct the dynamics of heat shock protein receiving temperature signal, model the cycles of temperature input to the circadian clock, determine optimal parameters, make model reliability analysis, and predict the expressions and dynamics of model variables.

2021年3月1日 · Heat stress has been defined as the rise of temperature for a period of time higher than a threshold level, thereby permanently affecting the plant growth and development. Day or night temperature is considered as the major limiting factor for plant growth.

2019年3月18日 · To determine the direct contribution of time of day and/or the clock to differential heat stress responses, we probed wild-type and mutants of the circadian clock genes CCA1, LHY, PRR7, and PRR9 following exposure to heat (37 °C) and moderate cold (10 °C) in the early morning (ZT1) and afternoon (ZT6).

2022年10月24日 · In tomato plants, the circadian clock is a biological clock to integrate environmental cues such as light-dark photoperiod and temperature cycles with their own biological rhythms in a 24-hour period.

GIGANTEA (GI) is a protein that regulates circadian rhythms and is essential for various physiological processes that influence abiotic stress resistance in plants. However, when tomatoes were exposed to high temperatures, their biological rhythms were disrupted.

In order to identify genes regulated by diurnal and circadian rhythms, and to establish possible functional relations between photoreceptors and the circadian clock in tomato, we monitored the temporal transcription pattern in plants entrained to long-day conditions, either by large scale comparative profiling, or using a focused approach over ...

2008年7月30日 · We report a large series of transcript oscillations that shed light on the complex network of interactions among tomato photoreceptors and clock-related genes. Alteration of cryptochrome gene expression induced major changes in the rhythmic oscillations of several other gene transcripts.

2024年1月11日 · Circadian clock genes play essential roles in allowing plants to maintain homeostasis by accommodating temperature changes within the normal temperature range or by altering protein properties and morphogenesis at the cellular level for plant survival and growth under temperature stress conditions.

Here we investigate the stochastic entrainment of the circadian clock in the model crop tomato, subject to different thermoperiods. We first proposed the deterministic model of the thermoresponsive circadian clock.

2018年10月5日 · Splicing factors, SNW/SKI-interacting protein (SKIP) and SM-like (LSM) would mediate the heat stress-induced alternative splicing of key clock genes, such as circadian clock-associated 1 (CCA1), pseudo-response regulators, and early flowering 3.
