Pyankovia brachiata (Pall.) Akhani & Roalson 2007, is an annual plant belonging to the genus Pyankovia, family Amaranthaceae, which is widely distributed in the inland deserts of Northwest China. P. brachiata was previously categorized under the genus Salsola in Salsoleae and has been a long-standing topic of debate. Therefore, the complete chloroplast genome of P. brachiata must be studied to provide a theoretical reference for species classification. In this study, we sequenced P. brachiata samples and determined the species’ complete chloroplast genome. The complete chloroplast genome was 149,922 bp in length, with one large single copy (LSC: 83,565 bp), one small single copy (SSC: 18,535 bp), and two inverted repeat regions (IRa and IRb, 23,911 bp each). It contains 132 genes, including 87 protein-coding, eight rRNA, and 37 tRNA genes. The phylogenetic position showed that P. brachiata has the closest relationship with Caroxylon passerinum (accession number: NC057191.1). This study will provide genetic information and be beneficial to understanding the systematic position of P. brachiata within the Amaranthaceae.

Stilpnolepis centiflora, a monotypic genus of the Asteraceae, is an endemic desert species in Northern China. However, information on the chloroplast (cp) genome of this species is limited. In this study, we present the complete chloroplast genome sequence of S. centiflora obtained by high-throughput nextgeneration sequencing technology. The whole cp genome was 151017 bp long and comprised 133 genes, including 88 proteincoding genes, 37 tRNA genes, and 8 rRNA genes. The S. centiflora cp genome had a GC content of 37.35%. Phylogenetic tree revealed that S. centiflora was closely related to the taxa in the genus Artemisia and Chrysanthemum. Our results would be helpful for species identification and promote our understanding of the phylogeny of Stilpnolepis within the Asteraceae family.
