We sequenced the plastid genomes of three diatoms from the genus , including two strains formerly designated as . At 208,097 and 216,580 bp, the plastid genomes of the latter strains are the largest ever sequenced among diatoms and their increased size is explained by the massive expansion of the inverted repeat region. Important rearrangements of gene order were identified among the two populations of cf. . The other sequenced chloroplast genome is 1.5 times smaller compared with those of the cf. strains and it features an usual quadripartite structure. The extensive structural changes reported here for the genus are compared with those previously observed for other algae and plants displaying large plastid genomes.
我们对三个属的三种硅藻的质体基因组进行了测序，其中包括两个以前被指定为 的菌株。后两个菌株的质体基因组分别为 208097 和 216580bp，是硅藻中测序过的最大基因组，其大小的增加是由于反向重复区的大量扩张所致。在 cf. 种群中发现了两个群体之间的重要基因顺序重排。另一个测序的叶绿体基因组与 cf. 菌株相比小了 1.5 倍，并且具有不寻常的四分体结构。与其他显示大质体基因组的藻类和植物相比，这里报道的属的广泛结构变化进行了比较。
