Abstract

Triticum militinae Zhuk. et Migusch., a tetraploid wheat with the GAA genome, is considered a natural naked mutant of Triticum timopheevii Zhuk. Previously, the karyotype and crossing characteristics of this wheat were examined. To clarify the origin and relationships of T. militinae with other representatives of the wheat family, analysis of its chloroplast genome, which remained unexplored, is of great interest. In the present study, for the first time, sequencing and annotation of the complete chloroplast genome of T. militinae, the size of which was found to be 135 898 bp, was conducted. The plastome of this wheat is composed of two inverted repeats, each of 21 552 bp in length, the small single-copy (SSC) region of 12 791 bp, and the large single-copy (LSC) region of 80 003 bp. The chloroplast genome of T. militinae contains 132 annotated structural genes, of which 85 genes are protein-coding, 31 are tRNA genes, and four genes code for rRNA.

Triticum militinae--四倍体小麦 Triticum timopheevii Zhuk 的 "天然突变体"--叶绿体基因组的测序和注释
摘要-Triticum militinae Zhuk.此前,对这种小麦的核型和杂交特性进行了研究。为了弄清 T. militinae 的起源及其与小麦家族其他代表的关系,对其叶绿体基因组的分析是非常有意义的。本研究首次对 T. militinae 完整的叶绿体基因组进行了测序和注释,发现其大小为 135 898 bp。这种小麦的质粒体由两个长度各为 21 552 bp 的倒置重复序列、长度为 12 791 bp 的小单拷贝(SSC)区和长度为 80 003 bp 的大单拷贝(LSC)区组成。T. militinae 的叶绿体基因组包含 132 个注释结构基因,其中 85 个基因编码蛋白质,31 个基因编码 tRNA,4 个基因编码 rRNA。
