The genus Euphorbia (Euphorbiaceae) has near-cosmopolitan distribution and serves as a significant resource for both ornamental medicinal purposes. Despite its economic importance, Euphorbia's taxonomy long been challenged by the intricate nature of morphological traits exhibiting high levels convergence. While molecular markers are essential phylogenetic studies, their availability limited. To address this gap, we conducted comparative analyses focusing on chloroplast (CP) genomes nine species, incorporating three newly sequenced annotated accessions.

Camellia gigantocarpa is one of the oil-tea trees whose seeds can be used to extract high-quality vegetable oil. To date, there are no data on mitochondrial genome tree, in contrast tea-tree C. sinensis, which belongs same genus. In this paper, we present first complete genomes obtained using PacBio Hi-Fi (high-fidelity) and Hi-C sequencing technologies anchor 970,410 bp assembly into a single sequence. A set 44 protein-coding genes, 22 non-coding 746 simple sequence repeats (SSRs), more than 201 kb repetitive sequences were annotated assembly. The high percentage (20.81%) C.sinensis (22.15%, tea tree) compared Arabidopsis thaliana (4.96%) significantly increased mitogenome size genus Camellia. comparison between sinensis revealed genes exhibit variance gene order low substitution rate within Information provides better understanding structure evolution may contribute further study after-ripening process trees.

Abstract Background Toxicodendron vernicifluum , belonging to the family Anacardiaceae, is an important commercial arbor species, which can provide us with raw lacquer, excellent adhesive and painting material used make lacquer ware. Compared diploid, triploid tree has a higher yield of stronger resistance stress . Triploid T. was newly discovered natural tree. However, taxonomy remained uncertain. Here, we sequenced analyzed complete chloroplast (cp) genome compared it related species genus based on SSR markers. Results The plastome 158,221 bp in length, including pair inverted repeats (IRs) 26,462 bp, separated by large single-copy region 86,951 small 18,346 bp. In total, 132 genes 87 protein-coding genes, 37 tRNA 8 rRNA were identified Among these, 16 duplicated IR regions, 14 contain one intron, while three two introns. After nucleotide substitutions, seven inversions genomes, eight hotspot regions found, could be useful molecular genetic markers for future population genetics. Phylogenetic analyses showed that sister cv. Dahongpao Hongpigaobachi. Moreover, phylogenetic clustering all samples Hongpigaobachi group, succedaneum another consistent cp morphological analysis. Conclusions current genomic datasets pivotal resources determine relationships, variety identification, breeding resource exploitation, diversity-related studies
