Chloroplast Genome Evolution of Hamamelidaceae at Subfamily Level

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(4)

Published: March 27, 2025

ABSTRACT The Hamamelidaceae is significant for its contributions to construction, furniture making, and ornamental use, including 26 genera 119 species. However, complete chloroplast genome sequences of species have been reported less frequently. In this study, five were newly sequenced, seven others available genomes added compare the evolution in at subfamily level. results indicated that size ranged from 158,116 159,941 bp, encoding 79 81 protein‐coding genes, four ribosomal RNA 30 31 transfer genes. A robust phylogenetic tree was obtained using genomes, supporting all formed a monophyletic group divided into subfamilies. Exbucklandioideae first diverged within Hamamelidaceae, followed by Mytilarioideae, Disanthoideae, Hamamelidoideae, which clade. Furthermore, three new potential DNA barcodes provided: trnH‐psbA , psbJ‐petA ycf1 . This study confirms data provide more accurate confident resolution relationships Hamamelidaceae. These genomic not only enhance understanding but also better

Phylogeny and evolutionary dynamics of the Rubia genus based on the chloroplast genome of Rubia tibetica

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Rubia tibetica, a well-known medicinal plant, holds significant value. In this study, we sequenced and assembled the complete chloroplast genome of R. tibetica conducted comparative analyses with four other species to provide insights into structure, selective pressure, phylogenetic relationships. The was 154,901 bp in length exhibited typical quadripartite circular structure. Comparative analysis revealed highly conserved structure among species, sizes ranging from 153,555 155,108 GC content approximately 37%. Codon usage indicated preference for A/U-ending codons. Selective pressure identified relaxed selection genes such as rps15 petA, suggesting species-specific adaptive strategies. Two hypervariable regions, rps16-trnQ psaJ-rps18, were experimentally validated potential molecular markers through PCR amplification sequencing. However, sequencing results region differed reference genome, requiring further investigation. Phylogenetic performed using maximum likelihood (ML) based on sequences five confirmed monophyly genus, occupying basal position. This retention ancestral traits adaptation unique environment Qinghai-Tibet Plateau. Molecular dating divergence times consistent geological climatic events region. These findings critical evolutionary dynamics offer valuable resources their classification, conservation, application.
