Chloroplasts isolated from the siphonous green alga Codium fragile yield circular DNA molecules averaging 27.3 micrometers in length and 56 x 10(6) daltons in molecular size. This chloroplast genome is 25 to 30 percent smaller than any reported. The small size of the Codium chloroplast genome may represent a primitive evolutionary condition in green plants.
从丝状绿色海藻脆杆藻中分离出的叶绿体产生平均长度为 27.3 微米、分子量为 56 x 10(6) 道尔顿的环状 DNA 分子。这个叶绿体基因组比任何已报道的都要小 25%到 30%。脆杆藻叶绿体基因组的小尺寸可能代表了绿色植物进化的原始状态。
