Characterization of the complete chloroplast genome of Populus deltoides Zhonglin 2025.

ABSTRACT: The complete chloroplast genome of Populus deltoides was characterized by reference-based assembly using whole-genome sequencing data. The total chloroplast genome size of Populus deltoides included a pair of inverted repeat regions (IRs) of 27,649 bp each, a small single-copy region (SSC) of 16,563 bp, and large single-copy region (LSC) of 85,096 bp, which was 156,957 bp in length. A total of 109 genes were predicted from the chloroplast genome, including 83 protein-coding genes, 22 tRNA genes, and four rRNA genes. The GC content of chloroplast genome for Populus deltoides was 36.68%. The phylogenetic analysis based on the reported chloroplast genomes of Populus showed that the chloroplast of the Populus deltoides is most closely related to the Populus fremontii. The complete chloroplast genome of Populus deltoides provides new insights into Populus evolutionary and genomic studies.

The complete chloroplast genome sequence of Populus deltoides 'Siyang-2'.

Project description:Populus deltoides 'Siyang-2' is an improved variety of forest trees that have been identified recently. It shows superior growth performance compared to other local cultivars in the region of Yangtze-Huaihe in China. In this study, the whole chloroplast (cp) genome sequence of 'Siyang-2' was assembled and characterized by high-throughput sequencing data. The complete cp genome was 156,957 bp in length, containing a large single-copy region (LSC) of 85,096 bp, and a small single-copy region (SSC) of 16,563 bp, which were separated by a pair of 27,649 bp inverted repeat regions (IRs). The cp genome contained 131 genes, including 86 protein-coding genes, 37 tRNA genes, and 8 ribosomal RNA genes. Most of the gene species occur as a single copy, while 20 gene species occur in double copies. The overall GC content of 'Siyang-2' cp genome is 34.6%, while the corresponding values of the LSC, SSC, and IR regions are 34.5%, 30.6%, 41.9%, respectively. The complete cp genome provides valuable phylogenetic and cp genetic engineering studies of this important improved poplar species P. deltoides 'Siyang-2'.
