Abstract Background A robust molecular phylogeny is fundamental for developing a stable classification and providing solid framework to understand patterns of diversification, historical biogeography, character evolution. As the sixth largest angiosperm family, Lamiaceae, or mint consitutes major source aromatic oil, wood, ornamentals, culinary medicinal herbs, making it an exceptionally important group ecologically, ethnobotanically, floristically. The lack reliable phylogenetic this family has thus far hindered broad-scale biogeographic studies our comprehension diversification. Although significant progress been made towards clarifying Lamiaceae relationships during past three decades, resolution backbone at tribal level remained one greatest challenges due limited availability genetic data. Results We performed analyses infer using 79 protein-coding plastid genes from 175 accessions representing 170 taxa, genera, all 12 subfamilies. Both maximum likelihood Bayesian yielded more hypothesis relative previous supported monophyly subfamilies, 22 tribes, which are newly recognized in study. consequence, we propose updated phylogenetically informed that supplemented with detailed summary taxonomic history, generic species diversity, morphology, synapomorphies, distribution each subfamily tribe. Conclusions Increased taxon sampling conjoined based on plastome sequences provided support both deep shallow nodes offers new insights into among tribes subfamilies Lamiaceae. This will serve as future classification, evolution, Graphical abstract

Abstract The family Lauraceae is a major component of tropical and subtropical forests worldwide, includes some commercially important timber trees medicinal plants. However, phylogenetic relationships within have long been problematic due to low sequence divergence in commonly used markers, even between morphologically distinct taxa the family. Here we present analyses 43 newly generated plastomes together with 77 obtained from GenBank, representing 24 genera 17 related families angiosperms, plus nine barcodes 19 additional species 18 Lauraceae, order reconstruct highly supported for Lauraceae. Our phylogeny supports relationships: sisterhood clade containing Hernandiaceae Monimiaceae, Atherospermataceae Gomortegaceae being next sister groups, followed by Calycanthaceae. results highlight monophyletic well‐supported clades as follows: Hypodaphnis clade, Beilschmiedia – Cryptocarya Cassytha Neocinnamomum Caryodaphnopsis Chlorocardium Mezilaurus Machilus Persea Cinnamomum Ocotea Laurus Neolitsea clade. topology recovered here consistent patterns plastome structural evolution morphological synapomorphies reported previously. More specifically, flower sex, living type, inflorescence ovary position, anther locus number, leaf arrangement, venation, lateral vein tree height, location all represent different lineages. findings taxonomic implications two new tribes, Caryodaphnopsideae Neocinnamomeae, are described, composition four other tribes updated. provides robust framework through which address evolutionary history Magnoliids, third‐largest group Mesangiospermae.

Insights into acylation mechanisms: co‐expression of serine carboxypeptidase‐like acyltransferases and their non‐catalytic companion paralogs

The Plant Journal, Год журнала: 2022, Номер 111(1), С. 117 - 133

Опубликована: Апрель 19, 2022

SUMMARY Serine carboxypeptidase‐like acyltransferases (SCPL‐ATs) play a vital role in the diversification of plant metabolites. Galloylated flavan‐3‐ols highly accumulate tea ( Camellia sinensis ), grape Vitis vinifera and persimmon Diospyros kaki ). To date, biosynthetic mechanism these compounds remains unknown. Herein, we report that two SCPL‐AT paralogs are involved galloylation flavan‐3‐ols: CsSCPL4, which contains conserved catalytic triad S‐D‐H, CsSCPL5, has alternative T‐D‐Y. Integrated data from transgenic plants, recombinant enzymes, gene mutations showed CsSCPL4 is acyltransferase, while CsSCPL5 non‐catalytic companion paralog (NCCP). Co‐expression likely responsible for galloylation. Furthermore, pull‐down co‐immunoprecipitation assays interact, increasing protein stability promoting post‐translational processing. Moreover, phylogenetic analyses revealed their homologs co‐exist galloylated flavan‐3‐ol‐ or hydrolyzable tannin‐rich species. Enzymatic further necessity co‐expression those acyltransferase activity. Evolution analysis residues may have taken place about 10 million years ago. These findings show SCPL‐ATs NCCPs contributes to acylation kingdom.

Soil microbes mediate soil organic carbon (SOC) storage by affecting microbial residue (C) in terrestrial ecosystems, a main source of SOC. However, how C accumulation changes during the conversion subtropical primary forest to plantations and role community structure regulating these remain unclear. Here, effects from on three plantations, including tea (Camellia sinensis var. assamica), walnut (Juglans regia), macadamia (Macadamia integrifolia). We assessed amino sugars content relative importance structure, fertility, aboveground biomass four types southwest Yunnan province, China. Our results show that total accounted for 27.8 % SOC average across all types, fungal contributed more than bacterial different types. Conversion decreased fungal, bacterial, plantation except tea. Microbial contents was significantly lower plantation. Fungal increased with increasing composition, abundance, fertility. fertility regulated accumulation, which major determinant via its influence abundance. Overall, we found abundance change composition. also negatively correlated C, while positively related accumulation. Ascomycota most important phylum C. These findings suggest are principal regulators plantations.

Abstract Background The era of high throughput sequencing offers new paths to identifying species boundaries that are complementary traditional morphology-based delimitations. De novo delimitation using or DNA super-barcodes serve as efficient approaches recognizing putative (molecular operational taxonomic units, MOTUs). Tea plants ( Camellia sect. Thea ) form a group morphologically similar with significant economic value, providing the raw material for tea, which is most popular nonalcoholic caffeine-containing beverage in world. Taxonomic challenges have arisen from vague this group. Results Based on comprehensive sampling C. by far (165 individuals 39 morphospecies), we applied three de methods (ASAP, PTP, and mPTP) plastome data provide an independent evaluation tea plants. Comparing MOTU partitions morphospecies, particularly tested congruence MOTUs resulting different methods. We recognized 28 consensus within , while tentatively suggesting 11 morphospecies be discarded. Ten were uncovered complexes need further study integrating other evidence. Our results also showed strong imbalance among analyzed terms number molecular diagnostic characters. Conclusion This serves solid step forward underlying plants, needed evidence-based framework utilization conservation economically important plant
