<b>Comparative plastome analyses of early-diverging Solanaceae reveal structural evolution, codon usage bias, and episodic diversifying selection</b> rushan yan (23809063) Genomics plastome comparative genomics episodic diversifying selection <p dir="ltr">This dataset contains the complete chloroplast genome (plastome) sequences and associated annotations of 53 Solanaceae species analyzed in the study "Comparative plastome analyses of early-diverging Solanaceae reveal structural evolution, codon usage bias, and episodic diversifying selection". The dataset consists of: 7 newly de novo assembled plastomes spanning early-diverging to derived lineages (<i>Schizanthus grahamii</i>, <i>Salpiglossis sinuata</i>, <i>Cestrum elegans</i>, <i>Vestia foetida</i>, <i>Streptosolen jamesonii</i>, <i>Grammosolen truncatus</i>, and <i>Athenaea wettsteiniana</i>)；46 publicly available plastomes retrieved from NCBI.</p><p dir="ltr">These genomic resources were utilized in the associated study to characterize structural evolution, investigate codon usage bias, identify simple sequence repeats (SSRs) and mutational hotspots as candidate DNA barcoding markers, detect signatures of episodic diversifying selection across plastid genes, and reconstruct a comprehensive plastid-based maternal phylogeny capturing the broad phylogenetic breadth of the Solanaceae family.</p> 2026-10-05T15:19:44Z Dataset Dataset 10.6084/m9.figshare.34070595.v1 https://figshare.com/articles/dataset/_b_Comparative_plastome_analyses_of_early-diverging_Solanaceae_reveal_structural_evolution_codon_usage_bias_and_episodic_diversifying_selection_b_/34070595 CC BY 4.0
