The complete chloroplast genome of japonica type weedy rice (Oryza sativa f. spontanea)

As a noxious weed, weedy rice (Oryza sativa f. spontanea Roshev. 1931) has threatened global food security and sustainable crop production. On the other hand, weedy rice has a strong tolerance for abiotic stresses and the potential to provide rich resources for rice genetic improvement. Thus, for a...

Description
Summary:As a noxious weed, weedy rice (Oryza sativa f. spontanea Roshev. 1931) has threatened global food security and sustainable crop production. On the other hand, weedy rice has a strong tolerance for abiotic stresses and the potential to provide rich resources for rice genetic improvement. Thus, for a more comprehensive understanding of its speciation, we sequenced and assembled the first complete chloroplast genome of Oryza sativa f. spontanea (japonica type). The complete chloroplast genome was 134,555 bp in length and encoded 133 genes, including 83 protein-coding genes, 42 tRNA genes and 8 rRNA genes. Phylogenetic analysis revealed that the indica-japonica differentiation of weedy rice was closely related to cultivated rice, and Oryza sativa f. spontanea (japonica type) was genetically more closely clustered with cultivated rice O. sativa (japonica type) than O. nivara or other wild rice.
