The bioactive compounds were extracted in different organic solvents (hexane, ethanol and ethyl acetate) and analyzed by column chromatography, thin-layer chromatography, high-performance liquid chromatography and gas chromatography-mass spectrophotometry (GC-MS). Three distinct fractions were collected and subsequently examined, one from ethyl acetate extraction (I) and two from ethanolic extraction (II and III). p-Coumaric acid was the major phenolic acid from the ethyl acetate extracts (0.11 ± 0.023 mg/kg) while resorcinol was the major phenolic compound from the ethanol extracts (25.00 ± 3.21 mg/kg). Twenty-four bioactive compounds were identified by GC-MS analysis where 1-docosanol pentafluoropropionate was the major bioactive compound in ethanol extracts. Among the ethanol extracts, the highest antioxidant activity was found in fraction III. The highest anti-bacterial activity values, measured in terms of the size of the inhibition zone (mm) against Bacillus cereus and Staphylococcus aureus, i.e. 24 ± 1.62 and 22 ± 2.19 mm, respectively, were attained at 24 µg/mL for fractions III and I. From the results achieved in this work, ethanol extracts of C. colocynthis aerial parts could be considered promising as antioxidant and anti-infectious agents.Keywords: Citrullus colocynthis aerial partsbioactive compoundshPLCGC-msantioxidantantibacterial Authors’ contributionAmmar B.

We resurrect S. jensenii from synonymy with the morphologically and molecularly variable S. obcordata because our molecular data show that they are distantly related. Chloroplast trnL-trnF and nuclear ITS sequences resolved S. obcordata in sect. Curtae and S. jensenii in sect. Apiculatae sister to S. obscura and we detected morphological differences in secondary pigmentation and leaf anatomy. The similarity comprises the absence of a pronounced keel in vegetative leaves and a weakly defined stem cortex. These features are virtually unknown in other species of Scapania and probably result from convergence in adaptation to the same environmental conditions as both taxa inhabit alluvial plains characterised by regular disturbance by flooding and covering with sand and silt. While S. obcordata is widespread in the northern Holarctic and known from the Antarctic, S. jensenii is known from few localities in Greenland, mainland Norway, the Chukchi Peninsula and the Swiss Alps. Its rarity, the absence of female plants and the lack of genetic variability suggest that S. jensenii underwent a bottleneck event.Keywords: adaptive evolutionAlpsbryophytesdisturbanceScapaniaceaesex ratiotaxonomyDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

It is one of the most important plants in the Ayurveda and Siddha systems of medicine, and is known as Raajabalaa and Bhumibalaa in Sanskrit. The present study aims to develop a profile of bioactive compounds using GC-MS analysis and evaluate their anticancer and antioxidant potential. GC-MS analysis revealed the presence of 18 compounds in the petroleum ether extract, 14 compounds in the acetone extract, 12 compounds in the ethanol extract, and 6 compounds in the chloroform extract. Gamma-sitosterol is the most abundant compound found in the petroleum ether (18.48%), acetone (34.25%), and ethanol (25.17%) extracts. In the chloroform extract, 1,2-Benzenedicarboxylic acid is the most abundant compound, comprising 74.77% of the extract. The chloroform extract demonstrated significant in vitro cytotoxic activity against the HepG2 cell line, as determined by the MTT assay, with an IC50 value of 47.53 µg/mL. In vitro antioxidant potential was studied using DPPH and ABTS assays. However, the ethanol extract exhibited the highest scavenging activity, with IC50 values of 46.48 µg/mL and 94.17 µg/mL against their respective standards.Keywords: AntioxidantAyurvedaCytotoxicityEthnomedicineHepG2Sida cordataDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

The effect of the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF4]) on photosynthesis was studied in Arabidopsis thaliana. Apparent effects on chlorosis and inhibition of photosynthetic capacity were observed. As [Bmim][BF4] concentrations increased, a time-dose effect was also observed. The maximum quantum yield (Fv/Fm), and the actual quantum yield of photosystem II (ΦPSII), both decreased; at the same time, the expression of psbA, a key gene of the photosystem II electron transport, was reduced by [Bmim][BF4] treatment. The synthesis of the large and small subunits of Rubisco were not affected by treatment. On the other hand, Rubisco activase (RCA) was significantly suppressed at the transcriptional level. Our results suggest that photochemistry of PSII as well as Rubisco activation are involved in ILs resistance.Key words: Arabidopsis thaliana; [Bmim][BF4]Chlorophyll fluorescencegene transcript levelDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

Several gene-flow limiting processes can drive divergence, including adaptive ecological differentiation or geographical isolation both constituting environmental-dependent reproductive barriers. Furthermore, the strength of these processes may be associated to the degree to which ecological niches are conserved and shared by phylogenetically related species. Here, we aim to disentangle these two alternatives reproductive barriers by evaluating the degree of ecological niche similarity among phylogenetically related species. We performed ecological niche modelling (ENM) on four species belonging to a recently diversified genus (Aquilegia, Ranunculaceae) occurring in montane environments of the Alpine and Apennine chains (southern Europe). Results show that niche differentiation among species is related to phylogenetic distinctiveness.Nevertheless, niche similarity tests indicated that the conditions selected by the species are more similar than expected from the null models, even though they are sparsely available in the respective ecological spaces, suggesting that the observed pattern may result from phylogenetic niche conservatism.These results, highlight that paleogeographic events in south-European mountains may have driven divergence by isolation in Aquilegia while partially retaining the possibly ancestral characters of the niches.Keywords: Aquilegiaecological niche modelsEuropean Alpine Systemniche conservatismniche overlapsimilarity testSpeciationDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

The potential anticancer properties of masticadienonic acid, tirucallol and pistachionic acid, which are secondary metabolites isolated from Pistacia vera, has not been reported to date against breast cancer cells. Therefore, in this study, we aimed to assess the antitumor effect of these metabolites and investigate their potential as an anticancer agents. The cytotoxic activity of the secondary metabolites were evaluated by MTT analysis method, and the apoptotic activity in cells were evaluated by DNA fragmentation and caspase-3 enzyme expression by immunocytochemical analysis. Our results showed that masticadienonic acid and tricallol strongly reduced cell profileration of cancer cell lines. We found that these compounds induced apoptotic processes by enhancing caspase-3 expression and DNA fragmentation. These results suggest that it would be desirable to further investigate these compounds for their anti-breast cancer potential.Keywords: PistachioMasticadienonic acidTirucallolApoptosisAnti-breast cancer activityCytotoxicityDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

We measured the EM diameter, root diameter, mantle width and volume share, share of tannin cell layers, EM density and length of L. sibirica fine roots in four main types of habitats across the altitudinal gradient in the Urals. The diversity of fungal mantle types depended on the type of habitat. The minimal diversity of fungal mantles and the prevalence of plectenchymatous mantles were found in moister and unfertile habitats of sphagnous type. In other types of habitats, the diversity of fungal mantle types was approximately twice higher. A combination of factors (habitat type and altitude) significantly determined all quantitative parameters of the Larix EMs under study. We found a reduction in the EM linear dimensions with increasing altitude and a deterioration of environmental conditions, accompanied by a decrease in their functional parameters with a slight increase in the EM density and the share of nonmycorrhizal roots.","PeriodicalId":54604,"journal":{"name":"Plant Biosystems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
