The diurnal and circadian expression of light-harvesting genes (Lhc) is well documented for many plant species of the 'Angiospermae' division. Here we present the diurnal mRNA levels of species of the Gymnospermae, Pteridophyta, Bryophyta and Phycophyta divisions. Except for four Coniferophytina species, diurnal Lhc mRNA accumulation is detected in fern, moss and algae, supporting the idea that the concept of 'ciracadian clock'-controlled gene expression is an ancient process. Possible reasons why plants need the 'circadian clock' control mechanism are discussed.
对于被子植物门的许多植物物种，光捕获基因（Lhc）的昼夜和生物钟表达已有充分记录。在此，我们展示了裸子植物门、蕨类植物门、苔藓植物门和藻类植物门物种的昼夜mRNA水平。除了四种松柏纲物种外，在蕨类植物、苔藓和藻类中检测到了Lhc mRNA的昼夜积累，这支持了“生物钟”控制基因表达的概念是一个古老过程的观点。文中还讨论了植物需要“生物钟”控制机制的可能原因。
