Tetrapyrroles play vital roles in various biological processes, including photosynthesis and respiration. Higher plants contain four classes of tetrapyrroles, namely, chlorophyll, heme, siroheme, and phytochromobilin. All of the tetrapyrroles are derived from a common biosynthetic pathway. Here we review recent progress in the research of tetrapyrrole biosynthesis from a cellular biological view. The progress consists of biochemical, structural, and genetic analyses, which contribute to our understanding of how the flow and the synthesis of tetrapyrrole molecules are regulated and how the potentially toxic intermediates of tetrapyrrole synthesis are maintained at low levels. We also describe interactions of tetrapyrrole biosynthesis and other cellular processes including the stay-green events, the cell-death program, and the plastid-to-nucleus signal transduction. Finally, we present several reports on attempts for agricultural and horticultural applications in which the tetrapyrrole biosynthesis pathway was genetically modified.

高等植物中的四吡咯生物合成

四吡咯在各种生物过程中起着至关重要的作用,包括光合作用和呼吸作用。高等植物含有四类四吡咯,即叶绿素、血红素、西罗血红素和植物色素。所有的四吡咯都来自一个共同的生物合成途径。在这里,我们从细胞生物学的角度回顾了四吡咯生物合成研究的最新进展。进展包括生化、结构和遗传分析,这有助于我们了解四吡咯分子的流动和合成如何受到调节,以及四吡咯合成的潜在毒性中间体如何保持在低水平。我们还描述了四吡咯生物合成和其他细胞过程的相互作用,包括保持绿色事件、细胞死亡程序、以及质体到细胞核的信号转导。最后,我们提出了几份关于对四吡咯生物合成途径进行基因改造的农业和园艺应用尝试的报告。
