摘要

在这项研究中，我们组装和注释了甘蓝的线粒体基因组（mitogenome）。该有丝分裂基因组全长219 964 bp， GC含量为45.25%。它由61个基因组成，其中包括35个蛋白质编码基因、23个转移RNA基因和3个核糖体RNA基因。其中只有11个基因含有内含子。密码子偏好分析显示，人们倾向于以a /U碱基结尾的密码子。系统发育分析表明，意大利甘蓝、灰霉病甘蓝和大写甘蓝亲缘关系密切。该参考有丝分裂基因组为研究芸苔属植物间的遗传保护、系统发育关系和分子育种策略提供了基础。

Complete mitogenome and phylogenetic analysis of Brassica oleracea L. var. italica Plenck.

In this study, we assembled and annotated the mitochondrial genome (mitogenome) of B. oleracea L. var. italica Plenck. This mitogenome was found to span 219 964 bp, with a GC content of 45.25%. It comprised 61 genes, including 35 protein-coding, 23 transfer RNA, and three ribosomal RNA genes. Among these, only 11 genes contained introns. Codon preference analysis revealed a bias toward codons ending in A/U bases. A phylogenetic analysis demonstrated a close relationship between B. oleracea L. var. italica Plenck, B. oleracea L. botrytis, and B. oleracea var. capitata. This reference mitogenome provides a basis for research on genetic conservation, phylogenetic relationships, and molecular breeding strategies among members of the Brassica genus.
