The complete chloroplast genome sequence of the <i>populus</i> cultivar “ <i>Populus × Beijingensis</i> ”: a type of unique Chinese <i>populus</i>

This study examines the chloroplast genome of <i>Populus × beijingensis</i>, a deciduous tree species from the genus <i>Populus</i> in the <i>Salicaceae</i> family, which is highly valued for its ecological and economic significance. The sequencing result shows that the chloroplast genome of <i>P.×beijingensis</i> is approximately 157,070 base pairs (bp) in length, with the large single-copy (LSC) region being 85,192 bp and the small single-copy (SSC) region at 16,564 bp. It encodes a total of 128 genes, comprising 84 protein-coding genes, 36 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. This research establishes a foundation for future studies on the genetic diversity and ecological adaptation of <i>P.×beijingensis</i> and other <i>Populus</i> species.
