A new study shows that Cladophorales green algae have the most unconventional chloroplast DNAs ever observed, whereby genes are located on small linear single-stranded palindromic elements. This puzzling architecture has parallels with mini-circular chloroplast genomes of dinoflagellates and raises many questions about how it arose and is maintained.
一项新的研究表明,Cladophorales 绿藻具有迄今为止观察到的最非常规的叶绿体 DNA,其中基因位于小型线性单链回文元件上。这种令人困惑的结构与甲藻的小型环状叶绿体基因组有相似之处,引发了许多关于它是如何产生和维持的问题。
