Two divergent chloroplast genome sequence clades captured in the domesticated rice gene pool may have significance for rice production.

ABSTRACT:

Background

The whole chloroplast genomes of 3018 rice genotypes were assembled from available sequence data by alignment with a reference rice chloroplast genome sequence, providing high quality chloroplast genomes for analysis of diversity on a much larger scale than in any previous plant study.

Results

Updated annotation of the chloroplast genome identified 13 more tRNA genes and 30 more introns and defined the function of more of the genes. Domesticated rice had chloroplast genomes that were distinct from those in wild relatives. Analysis confirms an Australian chloroplast clade as a sister to the domesticated clade. All domesticated rice genotypes could be assigned to one of two main clades suggesting the domestication of two distinct maternal genome clades that diverged
