我们发现了一个条纹模式的基因表达与昼夜节律生长的植物根基因表达的生物发光成像。我们的实验分析表明，条纹波的生物发光图像起源于根尖，是由一个连续的相位重置的昼夜振荡。还观察到了一些含有振荡区的复杂条纹波。我们成功地描述了这些模式的形成机制，使用一个不断增长的相位振荡器网络与相位复位边界条件。
We discovered a striped pattern of gene expression with circadian rhythms in growing plant roots using bioluminescent imaging of gene expression. Our experimental analysis revealed that the stripe wave in the bioluminescent image originated at the root tip and was caused by a continuous phase resetting of circadian oscillations. Some complex stripe waves containing arrhythmic regions were also observed. We succeeded in describing the formation mechanisms of these patterns using a growing phase oscillator network with a phase-resetting boundary condition.
