植物细胞中的线粒体和叶绿体起源于细菌内共生，它们仍然复制自己的基因组，并以与祖先相似的方式分裂。因此，细胞器转录可能与其增殖周期相协调。然而，这种可能性至今尚未被广泛探索，因为在大多数植物细胞中，有许多线粒体和叶绿体不同步增殖。一般认为，在真核植物细胞的进化过程中，基因组从细胞器转移到核基因组，使得细胞器功能的核控制成为可能。然而，没有显着的关系已被报道细胞器的转录组和宿主细胞周期之间，即使在衣原体reinhardtii。虽然细胞器增殖周期与维管植物中的细胞周期不协调，但在每个细胞仅包含一个叶绿体、一个叶绿体和一个细胞核的单细胞红蓝细菌Cyanidioschyzon merolae中，已知每个细胞器在细胞周期的特定阶段增殖。在这里，我们表明，大多数细胞器基因的表达是高度协调的细胞周期阶段，以及与光制度的聚类分析。此外，一个很强的相关性之间的基因表达谱在叶绿体和叶绿体中观察到，导致在细胞器增殖过程中共表达的功能相关的基因的网络的识别。
The mitochondria and chloroplasts in plant cells are originated from bacterial endosymbioses, and they still replicate their own genome and divide in a similar manner as their ancestors did. It is thus likely that the organelle transcription is coordinated with its proliferation cycle. However, this possibility has not extensively been explored to date, because in most plant cells there are many mitochondria and chloroplasts that proliferate asynchronously. It is generally believed that the gene transfer from the organellar to nuclear genome has enabled nuclear control of the organelle functions during the evolution of eukaryotic plant cells. Nevertheless, no significant relationship has been reported between the organelle transcriptome and the host cell cycle even in Chlamydomonas reinhardtii. While the organelle proliferation cycle is not coordinated with the cell cycle in vascular plants, in the unicellular red alga Cyanidioschyzon merolae that contains only one mitochondrion, one chloroplast, and one nucleus per cell, each of the organelles is known to proliferate at a specific phase of the cell cycle. Here, we show that the expression of most of the organelle genes is highly coordinated with the cell cycle phases as well as with light regimes in clustering analyses. In addition, a strong correlation was observed between the gene expression profiles in the mitochondrion and chloroplast, resulting in the identification of a network of functionally related genes that are co-expressed during organelle proliferation.
