Chloroplast Genomes of Chinese Rubus Species: Phylogenetic Analysis

Encompassing sequenced chloroplast genomes of Chinese Rubus species, with genome sizes ranging from 155,472 to 156,886 base pairs. It includes 131 genes per genome, comprising 88 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. The data was generated by Jian-Nan Chen to provide molecular evidence for the systematic classification of Rubus within Rosaceae.

Use Cases

• Perform phylogenetic analysis using the chloroplast genome sequences to delineate the eight evolutionary branches corresponding to Rubus subgenera.
• Analyze codon usage patterns and selection pressures on the 88 protein-coding genes to study evolutionary constraints.
• Compare the expansion and contraction of inverted repeat (IR) regions across different Chinese Rubus species.
• Identify and compare simple sequence repeats (SSRs) and long repeat sequences across the assembled chloroplast genomes.

Strengths

• Each chloroplast genome contains a defined set of 131 genes, including 88 protein-coding genes.
• Genome sequences have a specific size range from 155,472 to 156,886 base pairs.
• Data is structured to clarify phylogenetic relationships among Chinese endemic Rubus species.

Limitations

• The dataset is small in scale at 1.6 MB, indicating a limited number of genome sequences.
• Geographic scope is restricted to Chinese Rubus species, limiting applicability to other regions.
• Sample data and specific row/column counts are unavailable, hindering initial assessment of data structure.
