Chloroplast genome of a pair of Triticum aestivum L. recombinant inbred lines with significant difference in seed size

摘要

Wheat (Triticum aestivum L.), one of the most important crops belong to the Triticum genus of family Poaceae. Some of important cytoplasmic genes come from chloroplast genome. In this study, the chloroplast genome of a pair of T. aestivum recombinant inbred lines were sequenced, assembled, and annotated. Our results show this chloroplast genome consists of 137 unique genes, including 87 protein-coding genes, 42 tRNA genes, and 8 rRNA genes. A maximum-likelihood phylogenetic tree based on 15 chloroplast genomes revealed that the two T. aestivum are closely related to Triticum genus. The chloroplast genome could be used for wheat species identification, cytoplasmic inheritance gene functional study and breeding.
