Abstract Myricaria laxiflora, which grows along the Yangtze River in China, holds ornamental, ecological, and medicinal value. However, its wild population is threatened and currently designated protected as a national priority. The present research was the first to sequence and assemble M. laxiflora’s mitochondrial genome and examine its structural characteristics and phylogenetic relationships with other sequenced Caryophyllales species. The mitochondrial double-stranded closed-ring genome of M. laxiflora was found to be 389,949 bp in length, containing numerous repetitive sequences and RNA editing sites, with 34 protein encoding, 21 tRNA, and 3 rRNA genes. Although there are 22 fragments in the More >

Abstract Darwin’s finches are the most classic case of evolution. Early studies on the evolution of this species were mainly based on morphology. Until now, the mitochondrial genome of Geospiza magnirostris has been sequenced and the study explored the characteristics of the complete genome of G. magnirostris and verified the evolutionary position of it. The 13 PCGs initiated by ATN codons. The stop codons of three PCGs (ND2, COX3 and ND4) were incomplete, with only T- or TA- replacing complete form TAA or TAG. All the tRNA genes expressed a typical cloverleaf secondary structure, except for tRNA^Ser1(AGY), whose dihydrouridine (DHU)… More >
