Bauhinia s.s. belongs to the Cercidoideae subfamily, located at base of Leguminosae family. It displays a variety growth habits and morphologies, is widely utilized as both ornamental medicinal plants globally. The objective this research uncover chloroplast genomes species from Eastern Asia Southern Africa, thereby advancing our understanding diversity within genus. This study sequenced purpurea, brachycarpa var. microphylla, variegata candida, galpinii, monandra using Illumina platform conducted construction phylogenetic trees well estimation divergence times. Compared Asian species, IR regions African underwent contraction approximately 100–400 bp. analysis indicated that clustered into two distinct clades, with high support. occurred in late Paleocene, rps18 cemA genes were under positive selection. Six hypervariable screened for evolutionary studies super-barcode data used delimitation. results revealed certain differences between their species.

Analysis of Codon Usage Bias of 30 Chloroplast Genomes in Ulva (Ulvophyceae, Chlorophyta)

Genes, Journal Year: 2025, Volume and Issue: 16(5), P. 608 - 608

Published: May 21, 2025

Background: Ulva is a globally distributed genus with ecological and economic significance, yet the codon usage bias of chloroplast genome remains poorly understood. Methods: We assessed patterns their drivers by analyzing 30 genomes across 16 species. Results: The nucleotide composition analysis demonstrated that are rich in A/T, prefer to use codons ended A/T. relative synonymous suggested related species have similar patterns. A total 25 high-frequency 7–14 optimal were identified these genomes. ENC values ranged from 31.40 32.76, all which less than 35, illustrating strong genus. Our comparative analyses natural selection played main role formation bias. Furthermore, correlation indicated an influence base gene expression levels on Conclusions: This study provides first comprehensive genomes, improving our understanding genetics evolution economically ecologically important macroalgae.
