Oregano is a medicinal and aromatic plant of value in the pharmaceutical, food, feed additive, and cosmetic industries. Oregano breeding is still in its infancy compared with traditional crops. In this study, we evaluated the phenotypes of 12 oregano genotypes and generated F1progenies by hybridization. The density of leaf glandular secretory trichomes and the essential oil yield in the 12 oregano genotypes varied from 97–1017 per cm2and 0.17–1.67%, respectively. These genotypes were divided into four terpene chemotypes: carvacrol-, thymol-, germacrene D/β-caryophyllene-, and linalool/β-ocimene-type. Based on phenotypic data and considering terpene chemotypes as the main breeding goal, six oregano hybrid combinations were performed. Simple sequence repeat (SSR) markers were developed based on unpublished whole-genome sequencing data ofOriganum vulgare, and 64 codominant SSR primers were screened on the parents of the six oregano combinations. These codominant primers were used to determine the authenticity of 40 F1lines, and 37 true hybrids were identified. These 37 F1lines were divided into six terpene chemotypes: sabinene-, β-ocimene-, γ-terpinene-, thymol-, carvacrol-, andp-cymene-type, four of which (sabinene-, β-ocimene-, γ-terpinene-, andp-cymene-type) were novel (i.e., different from the chemotypes of parents). The terpene contents of 18 of the 37 F1lines were higher than those of their parents. The above results lay a strong foundation for the creating of new germplasm resources, constructing of genetic linkage map, and mapping quantitative trait loci (QTLs) of key horticultural traits, and provide insights into the mechanism of terpenoid biosynthesis in oregano.Keywords:oregano;essential oil;terpene chemotypes;hybrid;F1lines;SSR molecular marker

Cinnamomum camphora (L.) J. Presl can produce an abundance of terpenoids, and has four main chemotypes: linalool, eucalyptol, camphor, and borneol. Antioxidant activity and the chemical composition of extracts from the four chemotypes were investigated during spring (May), summer (July), and autumn (November) with the aim of developing natural antioxidants using suitable chemotypes of C. camphora in suitable seasons, together with their main terpenoids. The main antioxidant terpenoids were identified. The four chemotype extracts showed strong scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3- ethylbenzothiazoline-6-sulphonic acid) (ABTS) free radicals as well as O 2 – · and ·OH in July, due to the fact that their terpenoid content was at its highest during this month. Among the four chemotypes, the strongest scavenging activity was mainly detected in the linalool chemotype extracts, which had the highest terpenoid content. Among the ten main terpenoids in C. camphora extracts, ocimene, linalool, β -pinene, longifolene and eucalyptol showed stronger scavenging activity against DPPH free radicals, and ocimene exhibited the strongest scavenging activity. Extracts from the four chemotypes of C. camphora and their main terpenoids have the potential for development as natural antioxidants, with summer as the best season, linalool chemotypes as the optimum choice, and ocimene as the optimum compound. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

Metal phosphorus trichalcogenides, as a novel class of two-dimensional (2D) materials, attracted a lot of attention due to its antiferromagnetic ordering, excellent catalytic activity, and intrinsic electrical and optical properties. Herein, the FePS3 nanosheets exfoliated from the bulk counterpart by the sonication assisted liquid-phase exfoliation were applied in the photoelectrochemical-type (PEC) photodetector. The FePS3-based photoelectrode displays a short response time (rising time of 256 ms and decay time of 279 ms), large photocurrent density (3.2 μA cm–2), responsivity (31.94 μA cm–2 W–1), excellent long-term stability (more than 1000 s), and wide band detection (365–730 nm). Benefiting from the unique 2D structure of the FePS3 nanosheets and the flexibility of the PET substrate, the fabricated photoelectrode can maintain an outstanding photodetection performance after 500 cycles of bending and twisting. Furthermore, the PEC photodetector with a flexible sandwich structure was fabricated to make it more portable. This work promotes the application of 2D FePS3 nanosheets in optoelectronics and is of great significance to the practical application of the PEC device.

Agastache rugosa (AR) is a wildly cultivated medicinal and aromatic crop, which usually recommended to be harvested when the plant is exuberant with not flowering or in full flower stage. But there is no scientific basis for the support of the cognition. Therefore, the accumulation patterns of major active components during flower development (inflorescences with buds, full bloom and after full bloom stages) in two chemotypes (menthone type and estragole type) of AR were investigated by newly developed GC–QQQ–MS/MS and UPLC–QTOF–MS/MS methods. Five volatile (pulegone, menthone , estragole, methyleugenol and β -caryophyllene) and nine non-volatile components (rosmarinic acid, tilianin, acacetin 7- O -(6"- O -malonyl)- β - D -glucopyranoside, apigenin , agastachoside, isoagastachoside, acacetin 7- O -(2"- O -acetyl-6"- O -malonyl)- β - D -glucopyranoside, cirsimaritin and acacetin) in two chemotypes of AR samples at three stages were simultaneously quantified. It was found that the relatively higher contents of main volatile components were present in menthone type of AR collected at the full flower stage and in estragole type of AR at the after full bloom stage, whereas the relatively higher contents of main non-volatile components were present in menthone type of AR collected at the inflorescences with buds stage and in estragole type of AR at the after full bloom stage. Considering major active volatile and non-volatile components with higher levels, full bloom stage and after full bloom stage should be optimal harvesting time for menthone type and estragole type of AR, respectively.

Plant secondary metabolites can protect organisms against oxidative stress caused by adverse environmental conditions. Cinnamomum camphora (L.) J. Presl contains plentiful terpenoids and is subdivided into 5 chemotypes. To develop natural antioxidants using the plant terpenoids, the terpenoid composition and antioxidant abilities of methanol, ethyl acetate, n-hexane and petroleum ether extracts from linalool and eucalyptol chemotypes were investigated, and the solvent effects on in vitro antioxidant activity of 8 main terpenoids were analyzed. Meanwhile, the in vivo effects of two strong antioxidant terpenoids were evaluated. For the two chemotypes, the 4 solvents exhibited the same extracting effects on the terpenoid types, but methanol extracts contained the highest content of terpenoids, which should contribute to their strongest scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radicals. In linalool and eucalyptol chemotype extracts, linalool, eucalyptol, ocimene, α-pinene, D-limonene, terpinene, β-pinene and longifolene were the 8 main terpenoids. Among the 4 solvents, the 8 terpenoids showed the strongest free radical-scavenging activity with methanol as the reaction medium, which might result from strong-polarity methanol easily activating C = C unsaturated bonds in these compounds. This might also contribute to the strongest scavenging activity of methanol extracts against free radicals. Among these main components, ocimene and longifolene separately showed the strongest activity in scavenging DPPH and ABTS free radical. In in vivo assay, the two compounds significantly lowered the reactive oxygen species (ROS) levels in Chlamydomonas reinhardtii , a single-celled model organism, under H 2 O 2 stress, and the lowering effects gradually enhanced with increasing the compound concentration, resulting in the corresponding promoting effect on the algal growth. At the same concentration, longifolene showed the strongest effect on protecting the algal cells against oxidative stress. Therefore, methanol was suitable for extracting terpenoids in natural antioxidant development, and ocimene and longifolene were two strong antioxidant terpenoids without cell toxicity, with the latter having stronger in vivo antioxidant activity.

Photoelectric devices are extensively applied in optical logic systems, light communication, optical imaging, and so on. However, traditional photoelectric devices can only generate unidirectional photocurrent, which hinders the simplification and multifunctionality of devices. Recently, it has become a new research focus to achieve controllable reversal of the output photocurrent direction (bipolar current) in a photoelectric system. Considering that the device with bipolar current adds a reverse current operating state compared to traditional devices, the former is more suitable for developing new multifunctional photoelectric devices. Due to the existence of electrolytes, photoelectrochemical (PEC) systems contain chemical processes such as ion diffusion and migration and electrochemical reactions, which are unable to occur in solid-state transistor devices, and the effect of electrolyte pH on the performance of PEC systems is usually ignored. We prepared a MnPS3-based PEC-type photodetector and reversed photocurrents by adjusting the pH of electrolytes, i.e., the electrolyte-controlled photoelectrochemical photocurrent switching (PEPS) effect. We clarified the effect of pH values on the direction of photocurrent from the perspectives of electrolyte energy level rearrangement splitting and the kinetic theory of the semiconductor electrode. This work not only contributes to a deeper understanding of carrier transport in PEC processes but also inspires the development of advanced multifunctional photoelectric devices.

The construction of semiconductor heterojunctions is an effective approach to enhance the performance of optoelectronic devices. In this study, graphene-quantum-dots (GQDs) were grown on ZnO nanorods arrays in - situ to form intimate heterojunctions. The fabricated photoelectrochemical (PEC) photodetector based on ZnO/GQDs heterojunctions displayed good self-powering characteristics, with an on/off current ratio of approximately 21 at zero bias, which was almost seven-fold higher than that of the bare ZnO device. The responsivity and detectivity of the ZnO/GQDs-based photodetector were also enhanced compared with those of bare ZnO devices. A unique type-II band alignment was established at the ZnO/GQDs heterojunction interface, which facilitated the carrier transfer. Moreover, the ZnO/GQDs heterojunction reduced the passivation of the surface states, resulting in large energy-band bending and an internal electric field at the semiconductor/electrolyte interface, which provided a powerful driving force for the separation and transport of photogenerated carriers. These combined effects enhance the performance of the photodetector, indicating that this approach can be used to fabricate high-performance PEC optoelectronic devices.

Camphora officinarum Nees ex Wall ( C. officinarum ), a citral-rich aromatic plant, is recognized as an unrivalled natural source of citral for spice production. Its large-scale cultivation in China via the sustainable coppice-rotation system has markedly revitalized rural economies. Nevertheless, the genetic basis driving its prolific citral accumulation remains elusive. We conducted an integrated transcriptomic and metabolomic analysis comparing three citral type accessions (C1, C2, C3) with a non-citral type control (C0). Metabolomic profiling identified 904 leaf metabolites, with terpenoids representing the most abundant class (19.49%). Strikingly, GC-MS analysis unveiled a monoterpene-dominated essential oil composition in citral type C. officinarum leaves , characterized by four dominant constituents: geranial (36.9%-44.7%), neral (30.7%-34.1%), E-isocitral (2.2%-2.9%), and Z-isocitral (1.5%-2.1%). Integrated transcriptomic and metabolomic analysis highlighted critical key genes, acetyl-CoA C-acetyltransferase ( CoAACT ), hydroxymethylglutaryl-CoA synthase ( CoHMGS) , hydroxymethylglutaryl-CoA reductase ( CoHMGR ), phosphomevalonate decarboxylase ( CoMVD ), 1-deoxy-D-xylulose-5-phosphate synthase ( CoDXS ), geranylgeranyl diphosphate synthase, type Ⅲ ( CoGGPS) , farnesyl diphosphate synthase ( CoFDPS ) showed elevated expression, enhancing precursor availability. The geraniol synthase ( CoGES ) and alcohol dehydrogenase ( CoADH ) involved in citral synthesis were significantly up-regulated in citral type C. officinarum . These findings demonstrate that the quantitative disparities in terpenoid distribution and concentration collectively define the species’ unique aromatic identity, underscoring chemotype-specific metabolic regulation mechanisms, while also screening key genetic determinants of citral biosynthesis preliminarily, thereby laying the groundwork for precision breeding programs in aromatic C. officinarum .

Bi nanoplatelets (NPLs) with a narrow size distribution and high yield have been successfully fabricated by a novel two-step sonication-assisted solvothermal method . Applied as photo-electrochemical (PEC)-type photodetectors (PDs), it is shown that the Bi NPLs exhibit a pronounced photo-response ranging from the ultraviolet to the visible regions. The photo-response performance of Bi NPLs-based PDs was adjusted by external conditions and interpreted by density functional theory calculations in terms of the formation of the respective Bi-based compounds. The PEC results demonstrate that the optimal photocurrent density ( P ph ) and photoresponsivity ( R ph ) can reach 12.27 μA/cm 2 and 3016 μA/W in alkaline electrolytes , respectively. Besides, the Bi NPLs-based PDs exhibit superb long-term cycling stability (∼97.86% remained after 1000 cycles). We conclude that Bi NPLs demonstrate great promise as an emerging building block for the design of high-performance PEC-type PDs as well as other novel optoelectronic devices , holding the potential for breakthrough developments in these fields.

Sub-1-nm nanowires (NWs) with fascinating physicochemical properties have demonstrated remarkable potential for applications across various fields. However, it remains a great challenge to prepare sub-1-nm NWs with near-infrared (NIR) absorption characteristics and explore their optoelectronic applications, so far. Herein, a novel cation-exchange strategy in N, N-dimethylformamide (DMF) solvent is introduced to synthesize sub-1-nm PbSe NWs, starting from sub-1-nm ZnSe NWs. Theoretical calculations and nuclear magnetic resonance (NMR) measurements have confirmed that the cation exchange reaction in DMF effectively reduces the barriers for Zn 2+ extraction and Pb 2+ introduction compared to the conventional toluene/methanol system. Notably, the resulting sub-1-nm PbSe NWs exhibit a strong absorption peak at ≈940 nm. Leveraging their unique NIR absorption features and superior carrier transport properties, self-powered photoelectrochemical-type (PEC) photodetectors is fabricated based on sub-1-nm PbSe NWs embedded in polyvinylidene fluoride (PVDF) composite films. These photodetectors demonstrated exceptional photoresponse performance under 940 nm illumination (8.0 mW cm −2 ), with a typical on/off ratio of 4860, a detectivity of 4.65 × 10 11 Jones, and a responsivity of 113 mA W −1 . This work provides a new approach for developing and investigating NIR photoactive sub-1-nm semiconductor NWs with broad application prospects.

Plant terpenes are the main functional agents in forest bathing and have great value in several industries. To uncover the seasonal variation of Cinnamomum camphora monoterpene emission and the difference among the chemotypes for promoting the development of forest bathing and exploitation of monoterpenes using the species, the emission of monoterpenes and related gene expression in the camphor chemotype, eucalyptol chemotype, linalool chemotype and borneol chemotype of C. camphora were analyzed in May (spring), July (summer) and November (autumn), and the stored monoterpenes and storage structure were investigated. Eleocytes were the storage structure of monoterpenes in C. camphora , which widely existed in the leaf palisade tissue and spongy tissue, as well as around the glands and vascular bundles. The 4 chemotypes of C. camphora released different monoterpene components which mainly derived from the immediate emission after synthesis. Camphor, eucalyptol, linalool and endo-borneol showed the uppermost emission rate and were the typical monoterpenes in the corresponding chemotype, respectively, due to the high expression of the genes encoding bornyl diphosphate synthase ( E5.5.1.8 ), linalool synthase ( TSP14 ) and (+)-neomenthol dehydrogenase ( E1.1.1.208 ) for the biosynthesis of camphor, linalool and endo-borneol, respectively, and only expression of the gene encoding 1,8-cineole synthase ( TSP-cin ) for eucalyptol biosynthesis. Among the 4 chemotypes, the linalool chemotype showed the highest emission rate of monoterpenes in the same month (without significant difference with the eucalyptol chemotype in November), due to the high expression of the genes ( dxs , dxr , ispF , gcpE , and GGPS ) in methylerythritol-4-phosphate (MEP) pathway, α-terpineol synthase gene ( E4.2.3.111 ) and TSP14 . Among the 3 months, temperature was the remarkably varied meteorological condition. The highest monoterpene emission rate from the 4 chemotypes of C. camphora was detected in July, which should result from the up-regulated expression of related genes in monoterpene biosynthesis and improved vaporization and diffusion of stored monoterpenes under high temperature, with the former providing a major contribution.

Two-dimensional (2D) materials have demonstrated great performance and good application prospects in a variety of photodetectors, including photoelectrochemical (PEC)-type photodetectors, due to their superior optical and electrical properties. Among these, 2D Bi 2 Se 3 materials have drawn a lot of attention from scientists due to their special physical characteristics, such as a topological insulator, strong carrier mobility, and narrow bulk bandgap of 0.3 eV. Among the many methods for preparing Bi 2 Se 3 , the electrodeposition method stands out for its high adaptability and compatibility with PEC systems. Herein, through a simple electrodeposition method based on an electrochemical system, a Bi 2 Se 3 film-based PEC-type photodetector was constructed, which exhibits good and tunable photoresponse properties, as well as excellent cycle and time stability. This research demonstrates the potential of the Bi 2 Se 3 film created by electrodeposition as a photoanode material for photodetectors and offers a practical and prolongable method for creating photoanodes for PEC photodetectors.
