The complete chloroplast genome of weedy rye Secale cereale subsp. segetale

Abstract

Weedy rye (Secale cereale subsp. segetale Zhukov 1928) is a problematic weed species in wheat field. However, it can potentially provide valuable genetics resources to increase the genetic variations and introduce desirable genes for rye and wheat breeding. Here, we assembled the complete chloroplast genome of S. cereale subsp. segetale. The chloroplast genome is 137,051 bp in length, containing a large single copy region (81,090 bp), a small single copy region (12,795 bp) and two separated inverted repeat regions (21,583 bp). A total of 131 unique genes were annotated, consisting of 82 protein-coding genes, 41 tRNA genes, and 8 rRNA genes. The phylogenetic analysis showed that Secale cereale subsp. segetale (weedy rye) and S. cereale subsp. cereale (rye) clustered together as sisters to other Secale species.
