Spinach leaf fructose 2,6-bisphosphate levels increase rapidly during the first 15 minutes of a normal dark period followed by a gradual decline during the next 5 hours. The regulatory mechanism responsible for the dark-induced rise in fructose 2,6-bisphosphate levels can be counteracted by a brief exposure to light intensities greater than 1 microeinstein per square meter per second.
在正常的黑暗期的最初 15 分钟内,菠菜叶片中的 2,6-二磷酸果糖水平迅速增加,随后在接下来的 5 小时内逐渐下降。导致果糖 2,6-二磷酸水平在黑暗中升高的调节机制可以被短暂暴露于大于每平方米每秒 1 微爱因斯坦的光强度所抵消。
