Genome sequencing reveals the complete 156,695-bp chloroplast sequence of Albuca bracteata, highlighting its sister relationship to Albuca kirkii and aiding Ornithogaloideae authentication.
Albuca bracteata (syn. Ornithogalum caudatum) is an ornamental bulbous plant wth limited plastome data. We assembled its complete chloroplast genome (GenBank PZ425793) from high-throughput sequencing reads. The156.695-bp plastome comprised an 84,786-bp large single-copy region, an 18,555-bp small single-copy region, andtwo 26,677-bp inverted repeats, with 37.66% GC content and 533.8x mean coverage. It contained 113 unique genes79 protein-coding, 30 tRNA, and four rRNA genes). Phylogenetic analysis placed A. bracteata as sister to Albuca kirki. This plastome supports species authentication and comparative and phylogenetic studies of Ornithogaloideae.
