Description
Song Lu reports the first complete mitochondrial genome, the DNA inside the cell's energy-making mitochondria, for Anoectochilus emeiensis in this 2026 study. The orchid grows only on Mount Emei in Sichuan, China, and is prized for herbal medicine. Habitat damage and over-collecting cut its wild population sharply. It fell from about 5,000 plants in six groups during 2015 to fewer than 500 plants in two groups by 2023, so its genome matters for conservation.
Lu assembled the genome by combining two sequencing technologies and found an unusual structure split across 20 separate circular chromosomes. Together they total 490,926 base pairs and carry 29 protein-coding genes, 21 transfer RNA genes, and 3 ribosomal RNA genes. The paper also maps repeated sequences, RNA editing sites, and genes that migrated from the chloroplast, then compares this orchid with eight relatives.
