The complete chloroplast genome of weedy rice f. .

The emergence of weedy rice ( f. ) has been considered as a serious global agricultural problem in recent decades. To better understand its speciation, here we assembled the complete chloroplast genome of f. with the length of 134,502 bp. The assembly contains a large single-copy (LSC, 80,549 bp), a small single-copy (SSC, 12,347 bp) and a pair of inverted repeats (IRa and IRb, 20,803 bp each). A total of 132 unique genes were annotated, including 82 protein-coding genes, 42 tRNA genes and eight rRNA genes. Phylogenetic analysis showed that f. ( type) appears closely related to cultivated rice rather than wild rice, supporting the hypothesis that weedy rice originated from cultivated rice.
