Abstract
The Elsholtzieae, comprising ca. 7 genera and 70 species, is a small tribe of Lamiaceae (mint family). Members of Elsholtzieae are of high medicinal, aromatic, culinary, and ornamentals value. Despite the rich diversity and value of Elsholtzieae, few molecular markers or plastomes are available for phylogenetics. In the present study, we employed high-throughput sequencing to assemble two Mosla plastomes, M. dianthera and M. scabra, for the first time, and compared with other plastomes of Elsholtzieae. The plastomes of Elsholtzieae exhibited a quadripartite structure, ranging in size from 148,288 bp to 152,602 bp. Excepting the absence of the pseudogene rps19 in Elsholtzia densa, the exhaustive tally revealed the presence of 132 genes (113 unique genes). Among these, 85 protein-coding genes (CDS), 37 tRNA genes, 8 rRNA genes, and 2 pseudogenes (rps19 and ycf1) were annotated. Comparative analyses showed that the plastomes of these species have minor variations at the gene level. Notably, the E. eriostchya plastid genome exhibited increased GC content regions in the LSC and SSC, resulting in an increased overall GC content of the entire plastid genome. The E. densa plastid genome displayed modified boundaries due to inverted repeat (IR) contraction. The sequences of CDS and intergenic regions (IGS) with elevated variability were identified as potential molecular markers for taxonomic inquiries within Elsholtzieae. Phylogenetic analysis indicated that four genera formed monophyletic entities, with Mosla and Perilla forming a sister clade. This clade was, in turn, sister to Collinsonia, collectively forming a sister group to Elsholtzia. Both CDS, and CDS + IGS could construct a phylogenetic tree with stronger support. These findings facilitate species identification and DNA barcoding investigations in Elsholtzieae and provide a foundation for further exploration and resource utilization within this tribe.

Mining, expression, and phylogenetic analysis of volatile terpenoid biosynthesis-related genes in different tissues of ten Elsholtzia species based on transcriptomic analysis.

Abstract
We sequenced the leaf and inflorescence transcriptomes of 10 Elsholtzia species to mine genes related to the volatile terpenoid metabolic pathway. A total of 184.68 GB data and 1,231,162,678 clean reads were obtained from 20 Elsholtzia samples, and 333,848 unigenes with an average length of at least 1440 bp were obtained by Trinity assembly. KEGG pathway analysis showed that there were three pathways related to volatile terpene metabolism: terpenoid backbone biosynthesis (No. ko00900), monoterpenoid biosynthesis (No. ko00902), and sesquiterpenoid and triterpenoid biosynthesis (No. ko00909), with 437, 125, and 121 related unigenes, respectively. The essential oil content and composition in 20 Elsholtzia samples were determined by gas chromatography-mass spectrometry. The results showed that there were obvious interspecific differences among the 10 Elsholtzia species, but there were no significant differences between the different tissues among species. The expression levels of seven candidate genes involved in volatile terpenoid biosynthesis in Elsholtzia were further analyzed by quantitative real-time PCR. The results showed that HMGS had the highest expression among all genes, followed by GGPS4. In addition, there was not a significant correlation between the seven genes and the components with high essential oil contents. Combined with the essential oil components detected in this study, the possible biosynthetic pathway of the characteristic components in Elsholtzia plants was speculated to be a metabolic pathway with geraniol as the starting point and elsholtzione as the end product. Phylogenetic analysis was conducted using the nucleotide sequences of the geranyl diphosphate synthase candidate genes, and the results showed that genes related to the volatile terpenoid biosynthetic pathway may be more suitable gene fragments for resolving the Elsholtzia phylogeny.

Abstract
Mosladadoensis (Lamiaceae), a new species from the southern islands of South Korea, is described and illustrated. The new species is morphologically similar to M.chinensis, but is distinguished from the latter by having two types of hairs on its stems, wider leaf blades, longer corolla length, and ellipsoid nutlets with a narrowly U-shaped extended area of abscission scar. Mosladadoensis is also distinguished from the Chinese narrow endemic M.hangchouensis by having an included pistil to the corolla, smaller ellipsoid nutlets, and later flowering and fruiting season. Phylogenetic analyses, based on two nuclear ribosomal (ETS, ITS) and three chloroplast (rbcL, matK, trnL-F) DNA regions, confirmed that the new species was constructed as monophyletic, and that M.dadoensis and M.hangchouensis form a sister group with robust support. We hereby provide a detailed morphological description of M.dadoensis with its corresponding geographical distributions, and comparison tables of related taxa.

Abstract
Elsholtziazhongyangii (Lamiaceae), a new species from Sichuan Province, China, is described and illustrated. The new species is morphologically similar to E.feddeif.feddei, but it can be easily distinguished from E.feddeif.feddei by smaller corolla (3.2-3.5 mm vs. 4.5-5.3 mm), bract indumentum (glabrous, except margin ciliate vs. villous, especially on veins abaxially, glabrous adaxially) and bract stalked (ca. 1.2 mm vs. sessile). Phylogenetic analyses, based on two nuclear ribosomal (ETS, ITS) and five plastid (rbcL, matK, trnL-F, ycf1, ycf1-rps15) regions, confirmed that the new species formed a monophyletic clade with robust support. The new species is currently known from western Sichuan.
