许多微藻能够通过运行CO2浓缩机制（CCM）来适应CO2限制的环境，该机制由各种能量耦合的无机碳驱动（Ci; CO2和HCO 3 −）吸收系统。（下文称为衣原体），一种多功能的遗传模式生物，几十年来一直用于研究真核藻类中的活性Ci转运，但直到最近才出现了这些Ci摄取系统背后的许多分子细节。最近的进展，在遗传和分子的方法，结合衣原体和其他几个真核藻类的基因组测序已经解开了一些独特的特性与真核微藻的Ci摄取机制和Ci-再捕获系统。已经确定了几个很好的候选基因，在衣原体的Ci转运蛋白，和一些特定的基因产物已被链接到与不同的驯化状态相关的Ci摄取系统。本文将重点介绍近年来有关衣原体Ci摄取和Ci-再捕获功能组分的研究进展。
Many microalgae are capable of acclimating to CO2limited environments by operating a CO2concentrating mechanism (CCM), which is driven by various energy-coupled inorganic carbon (Ci; CO2and HCO3−) uptake systems.Chlamydomonas reinhardtii(hereafter, Chlamydomonas), a versatile genetic model organism, has been used for several decades to exemplify the active Ci transport in eukaryotic algae, but only recently have many molecular details behind these Ci uptake systems emerged. Recent advances in genetic and molecular approaches, combined with the genome sequencing of Chlamydomonas and several other eukaryotic algae have unraveled some unique characteristics associated with the Ci uptake mechanism and the Ci-recapture system in eukaryotic microalgae. Several good candidate genes for Ci transporters in Chlamydomonas have been identified, and a few specific gene products have been linked with the Ci uptake systems associated with the different acclimation states. This review will focus on the latest studies on characterization of functional components involved in the Ci uptake and the Ci-recapture in Chlamydomonas.
