摘要

Ircinia sp. (Dictyoceratida: ircininiidae)线粒体基因组是一个长16037 bp的圆形分子，包含14个蛋白质编码基因、2个核糖体RNA基因、2个转移RNA基因(trnW和trnM)和13个非编码片段。所有的基因都分布在同一条链上(h链)。h链的整体碱基组成为:T(37.84%)、C(11.22%)、A(24.81%)、G (26.13%)， GC-和at -偏度分别为0.399和-0.208，反映了h链之间碱基组成不平衡。非编码区总长度为1190 bp, AT含量较高(76.31%)。目前的线粒体基因组在基因顺序和内容上与兄弟种褐藻相同，但在非编码区存在两种重复序列，其中一种可能形成重复的发夹形成元件。

The complete mitochondrial genome of Ircinia sp. (Dictyoceratida: Irciniidae).

The mitochondrial genome of Ircinia sp. (Dictyoceratida: Irciniidae) is a circular molecule of 16,037 bp in length, containing 14 protein-coding genes, 2 ribosomal RNA genes, 2 transfer RNA genes (trnW and trnM) and 13 non-coding segments. All genes are distributed in the same strand (H-strand). The overall base composition of the H-strand is as follows: T (37.84%), C (11.22%), A (24.81%), G (26.13%), with GC- and AT-skew of 0.399 and -0.208, respectively, reflecting unbalanced base composition between the two strands. The non-coding regions are 1190 bp in total length, with high AT content (76.31%). The current mitochondrial genome is identical to that of sibling species I. strobilina in gene order and contents, but differs from the latter in the presence of two kinds of repetitive sequences in the non-coding regions, of which one could form repetitive hairpin-forming elements.

期刊介绍： Previously published under the title DNA Sequence (Vols 1-19.3), Mitochondrial DNA accepts original high-quality reports based on mapping, sequencing and analysis of mitochondrial DNA and RNA. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, medical genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The editorial board will also consider manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences.
