We report here the first mitogenome sequences for the chlorophyte class Chlorodendrophyceae. The mitogenomes of sp. CCMP 881 and (SAG 17.86) are 46,904 bp and 78,958 bp long, respectively, but their gene repertoires are almost identical. Each genome harbors an inverted repeat (IR). The 14,105-bp IR of . encodes seven genes in addition to a part of , whereas the 2445-bp IR of sp. CCMP 881 contains a single gene. Considering that an IR has also been found in the mitogenomes of certain earlier-diverging chlorophytes, the IRs of chlorodendrophycean algae probably represent ancestral features.
我们在此报告绿藻纲绿枝藻目的首个线粒体基因组序列。CCMP 881 种和(SAG 17.86)的线粒体基因组长度分别为 46,904 bp 和 78,958 bp,但它们的基因组成几乎相同。每个基因组都含有一个反向重复序列(IR)。的 14,105 bp 的 IR 除了的一部分外还编码七个基因,而 CCMP 881 种的 2445 bp 的 IR 只包含一个基因。鉴于在某些较早分化的绿藻的线粒体基因组中也发现了 IR,绿枝藻目藻类的 IR 可能代表了祖先特征。
