Interspecific hybridization has been extensively reported in Prosopis, a key genus of the Gran Chaco Americano, when species grow in sympatry or have adjacent distributions. Here, we performed a cytogenetic study in a hybrid zone of Prosopis alba, P. hassleri, and P. fiebrigii in southern South America. We characterized the karyotypes of pure species and the putative interspecific hybrids using chromosome fluorescent banding. Two karyotypes according to the heterochromatin pattern were identified, one corresponding to P. alba and the other to P. hassleri and P. fiebrigii; hybrid individuals presented P. alba or P. hassleri/P. fiebrigii karyotypes. The karyotypic formula and the number of nucleolar organizer regions were the same for all the studied morphotypes. Chromosome similarity among different species of the genus allows a continued hybridization and introgression between species and lends support to the hypothesis of a relatively recent diversification of Prosopis. Studying karyotype variation within a population could be a novel approach to the cytogenetic study of hybrids in the future.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"31 1","pages":"873 - 880"},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74395124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inhibitory activity of these fractions on lipoxygenase (LOX), cyclooxygenase (COX) and matrix metalloproteinase-9 (MMP-9) was investigated at 100 µg/mL concentration. The LOX enzyme was most effectively inhibited by the dichloromethane fraction (82.33%), whereas the COX-1, COX-2 and MMP-9 enzymes were most effectively inhibited by the ethyl acetate fraction (78.50%, 83.96% and 45.11%, respectively). The ethyl acetate fraction was selected for activity-guided fractionation based on the COX enzymes’ inhibitory activities by column chromatography. Only the ethyl acetate sub-fraction-1 showed inhibition on the COX-1 with 65.78%. The COX-2 inhibitory activities of the sub-fractions ranged from 59.96% to 97.62%. The main components were determined by HPLC-MS/MS as jaceidine in the dichloromethane fraction and rosmarinic acid in the ethyl acetate fraction. As far as we know, this study is the first to correlate the anti-inflammatory activity of O. minutiflorum extracts with LOX, COX and MMP-9 enzyme pathways and their secondary metabolites.

This first contribution to the floristic assessment of an Iranian archaeological site, aims to preserve its natural values. The Pasargadae World Heritage Site (sixth century BC) located at the border between the Zagros mountains and the Irano-Turanian region, showed a richness of 244 species, belonging to 38 families and 163 genera. The most represented families are Asteraceae (56), Poaceae (34) and Fabaceae (22). Herbaceous species represented 90% of the flora [therophytes (42%), hemicryptophytes (39%) and geophytes (9%)]. Asiatic, Irano-Turanian and Mediterranean species are the most recurrent species with a high component of endemic ones. Astragalus ghashghaicus, Taraxacum plicatulum, Acantholimon serotinum and Linaria farsensis were among the more interesting floristic elements. The comparison with past data, even if limited in quantity, indicated a good floristic conservation status. This research also showed the need to deepen our knowledge of the taxonomic features of this Iranian flora, sometimes still resulting in an ambiguous or unresolved status.

The results showed that seed germination of both weeds was significantly affected by the organs and concentration of saffron extracts. The highest germination rate of C. album was 2.38 seeds per day in the application of corms extract and the lowest germination rate was 2.12 seeds per day in the application of combination of leaf and corm extract. The highest seed vigor index of C. album was 12 in the application of leaf extract and the lowest was 9 in the application of leaf and corm extracts. In addition, the C. album application of the highest concentration of the extract (20%) led to the lowest weight of root, stem, seedlings, germination percentage, germination rate, seed vigor index, and number of normal seeds. In E. crus-galli, the increase in the concentration of the extract from 0 to 20% enhanced the mean germination time from 3.4 in control sample to 4.1 days with 20% extract concentration. All the applied extracts obtained from different saffron organs caused a significant reduction in germination traits in both species of weeds. Meanwhile the extracts of leaf and corm exerted the highest effects. Generally, the results showed that the application of 20% extract obtained from the combination of leaf and corm tissue provided the highest growth inhibition and lowest germination rate in both weeds.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"158 1","pages":"844 - 850"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77084614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate change phenomena are also identified as a strong driver in the habitat shift of many medicinal and aromatic plants (MAPs).

Therefore, the quest for suitable habitats of such species is taken as a challenge by various ecologists and conservationists. This study aims to predict the suitable habitats of Elwendia persica (Boiss.) Pimenov & Kljuykov, a threatened species for current and future climatic scenarios in the Indian Himalayan Region (IHR). The assessments for current and future climatic scenarios are accessed on the optimistic Representative Concentration Pathway 4.5 (RCP 4.5). The MaxENT algorithm has helped to predict the suitable habitat of the species in the study area. The model has predicted 1.12%, 2.37%, and 0.98% of the total study area as highly suitable habitats in current (2000) and future (2050 and 2070) climatic scenarios. South-eastern facing slopes are considered as the most suitable areas for the species in the Indian Himalayan Region.

This was coupled to field collection and chemical analysis of new samples of Cardamine waldsteinii. The data revealed a potentially new zinc hyperaccumulator species, C. waldsteinii, with 3050 mg kg−1 Zn in its leaves. This compares to 2210 mg kg−1 in the leaves of this species collected from the field. These values are below the notional hyperaccumulation threshold for zinc but are nevertheless unusual. The remarkably high accumulation factor for zinc are suggestive of the exceptional potential of C. waldsteinii for zinc uptake, even in non-metalliferous, zinc-deficient soils.

In this study, pollen from 11 species and one variety representing some of the genera in the tribe Alysseae were examined using light microscopy (LM) and scanning electron microscopy (SEM). The size of pollen is the smallest in Brachypus tabriziana (30.23 µm), conversely, the largest in Irania umbellata (47.17 µm) and Clastopus vestitus (46.60 µm) in the Alysseae. The pollen morphology of Irania umbellata deviated from I. multicaulis and was distinct in having perprolate, ornamentation reticulate, the thickest exine, and the polar axis length. In this study, the pollen morphology of some species of Fibigia, Brachypus, and Irania, was previously placed in the Fibigia genus in order to determine the significance of pollen features as taxonomic characters. In addition, our results indicated that Clastopus differs from the related genera Physoptychis and Straussiella, and pollen morphology conforms to the separation of the three genera.
