Abstract Background The genus Sanicula L. is a unique perennial herb that holds important medicinal values. Although the previous studies on provided us with good research basis, its taxonomic system and interspecific relationships have not been satisfactorily resolved, especially for those endemic to China. Moreover, evolutionary history of this also remains inadequately understood. plastid genomes possessing highly conserved structure limited rate proved be an effective tool studying plant phylogeny evolution.

Lilies are economically important monocots known for their ornamental flowers, bulbs, and large genomes. The absence of genomic information has impeded evolutionary studies genome-based breeding efforts. Here, we present reference genomes Lilium sargentiae (lily, 35.66 Gb) Gloriosa superba (flame lily, 5.09 Gb). giant lily genome is shaped by recent long terminal repeat retroelements. Phylogenetic analysis reveals diverse, independent origins cultivars. Gene families involved in sucrose starch metabolism significantly expanded the genome. Key homologs XTH22, SOC1, AP1/FUL-like genes regulate development, bud growth transition, floral transition bulbs. Colchicine biosynthetic gene clusters identified G. but absent L. sargentiae, highlighting colchicine evolution Colchicaceae. These insights enhance understanding Liliales evolution, providing a foundation future molecular research. perennial plants with flowers authors assemble two species, analyze phylogeny, flower stem development (bulbs lilies, rhizomes flame lilies), bulb transitions, biosynthesis.

Moreover, some ambiguities in phylogenetic relationships of this genus remain unresolved. Therefore, obtaining the whole chloroplast sequences L. comparative analysis along with other species crucial pivotal to understanding evolution as well populations. A multi-scale genome-level analysis, especially selection pressure, was conducted. Detailed third‑generation sequencing revealed genome 151,884 bp, an ordinary quadripartite protected structure comprising 37.0% GC. Overall, 113 different genes recognized genome, consisting 30 distinct tRNA genes, four ribosomal RNAs 79 unique protein-encoding genes.

Phylogenetic research in Tulipa (Liliaceae), a genus of significant economic and horticultural value, has relied on limited nuclear (mostly ribosomal internal transcribed spacer, nrITS) plastid DNA sequences, resulting low-resolution phylogenetic trees uncertain intrageneric classifications. The genus, noted for its large genome, presents discordant relationships among Amana, Erythronium, Tulipa, likely due to incomplete lineage sorting (ILS) and/or reticulate evolution. Thus, phylogenomic approaches are needed clarify these the conflicting signals within tribe Tulipeae. We newly sequenced 50 transcriptomes 46 species Tulipeae (including multiple accessions all four genera) one outgroup sister Lilieae (Notholirion campanulatum), downloaded 15 previously published supplement sampling. One dataset (74 protein-coding genes, PCGs) (2594 orthologous OGs) were constructed, with latter used tree inference based maximum likelihood (ML) multi-species coalescent (MSC) methods. To investigate causes gene discordance, "site con/discordance factors" (sCF sDF1/sDF2) calculated first, after which nodes displaying high or imbalanced sDF1/2 selected network analyses polytomy tests determine whether ILS evolution best explain incongruence. Key not resolved by this technique, especially those further investigated applying D-statistics QuIBL. failed reconstruct reliable unambiguous evolutionary history pervasive evolution, caused either obscured minority signal differing genomic compartments. However, we confirmed monophyly most subgenera, exception two small subgenus Orithyia, heterophylla was recovered as remainder whereas T. sinkiangensis clustered Tulipa. In contrast, traditional sections found be non-monophyletic.
