Abstract Rosaceae represents a vast and complex group of species, with its classification being intricate and contentious. The taxonomic placement of many species within this family has been a subject of ongoing debate. The study utilized the Illumina platform to sequence 19 plant species from 10 genera in the Rosaceae. The cp genomes, varying in size from 153,366 to 159,895 bp, followed the typical quadripartite organization consisting of a large single-copy (LSC) region (84,545 to 87,883 bp), a small single-copy (SSC) region (18,174 to 19,259 bp), and a pair of inverted repeat (IR) regions (25,310 to… More >

Abstract Azalea is a general designation of Rhododendron in the Ericaceae family. Rhododendron not only has high ornamental value but also has application value in ecological protection, medicine, and scientific research. In this study, we used Illumina and PacBio sequencing to assemble and annotate the entire chloroplast genomes (cp genomes) of four Rhododendron species. The chloroplast genomes of R. concinnum, R. henanense subsp. lingbaoense, R. micranthum, and R. simsii were assembled into 207,236, 208,015, 207,233, and 206,912 bp, respectively. All chloroplast genomes contain eight rRNA genes, with either 88 or 89 protein-coding genes. The four cp genomes were compared and analyzed by More >

Abstract Cryptomeria fortunei (Chinese cedar) is a highly adaptable woody species and one of the main forest plantation trees in subtropical high-altitude areas in China. However, there are few studies on its chloroplast (cp) genome. In this study, the complete cp genome of C. fortunei was sequenced and evaluated via comparative analyses with those of related species (formerly the Taxodiaceae) in Cupressaceae. The C. fortunei cp genome was 131,580 bp in length, and the GC content of the whole genome was 35.38%. It lost one relevant large inverted repeat and contained 114 unique genes, including 82 protein-coding genes, 28… More >
