This indicated that abiotic stress rather than herbivory might attenuate circadian clock function, similar to damping of the circadian oscillation induced by the feedback regulation by hormones, bacterial infection, bacterial PAMPs and toxins, and unidentified molecules found in herbivore regurgitant (Zhang et al., 2013; Li et al., 2018; Joo et al., 2019b; de Leone et al., 2020; Gao et al., 2020; Liang et al., 2024b; Fraser et al., 2024). This evidence concerns the gene CLOCK and bacterial infectious disease.
