In this study, we sequenced and characterized the complete mitochondrial genome of Sarcocheilichthys lacustris from Heilongjiang River (Amur River) at fuyuan county, Heilongjiang province, China. The circular mitochondrial genome of S. lacustris was determined to be 16,684 bp in length. It contains typical complement of 13 protein coding genes, 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs) and 1 control region.

Nannoglottis ravida is an extremely endangered species in the Qinghai-Tibet Plateau. Based on the second-generation high-throughput genome sequencing, we assembled the plastome of this species. The length of the total plastome is 152,324 bp with a typical quadripartite structure including a large single-copy region of 83,708 bp, a small single-copy region of 29,882 bp and two reverse repeat regions of 19,367 bp respectively. A total of 131 genes were annotated including 85 protein-coding genes (PCG), 36 tRNA genes, 8 rRNA genes and 2 pseudogenes. The constructed phylogenetic tree with other species of two tribes Senecioneae and Astereae based on plastomes suggests that N. ravida has a close relationship with the Astereae, but diverged early from this tribe.
