A study, was undertaken in three agro-climatic zones in southern Mali, to characterise P. biglobosa populations. Plots of 0.25 ha each were established in fields and fallows and adult trees in the plots were monitored. Natural regeneration was monitored in five subplots of 12.5 m x 12.5 m = 156.25 m2 each within each plot and data were collected from 2019 to 2021. Natural regeneration of P. biglobosa was found to be very weak in all sites. The mean density of seedlings varied from 11 to 24 seedlings ha-1 with a decreasing trend from 2019 to 2021. In Zanzoni, where the weakest regeneration was observed, the density varied from 0 to 8 seedlings ha-1. The highest density of seedlings was observed in Somasso in 2019 (42 seedlings ha-1) and 2020 (30 seedlings ha-1). In 2021, the highest density was observed in Diou (25 seedlings ha-1). The weakness of natural regeneration is very alarming for this tree species facing several other threats (ageing and decreasing adult tree populations, sanitary constraints, several pressures, etc.). It is therefore very important and imperative to investigate ways for regenerating the species for its sustainability and for maintaining the parklands biodiversity. Artificial regeneration (planting), could be the one and ultimate way to ensure the sustainability of P. biglobosa.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86763105","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}

This research contributes significantly to the understanding of biological resources employed in ethnoveterinary practices in the Haridwar district of Uttarakhand. This current study focuses on ethnoveterinary knowledge among ethnic populations in Haridwar and quantitatively documented the traditional knowledge about the usage of different medicinal herbs. The field survey was carried out at four sampling sites, i.e., Chilla range, Mohand range, Vindhyavasini hills, and Shyampur range. The ethnoveterinary information was documented and collected in the study areas through interviews, questionnaires, and group discussions with ethnic communities and traditional healers, primarily elderly shepherds and farmers. The collected data were quantitatively analysed utilizing the informant consensus factor (ICF), fidelity level (FL), and use value (UV). In this study, 102 medicinal plant species were identified in which herbs (58.8%) were the maximum used life forms. Leaves (27.1%) were found to be the most commonly used plant part. The oral mode of medication was used most often in the ethnoveterinary practices (79.4%) used. Quantitative analysis revealed that the most important species having high UV values for curing livestock was Zingiber officinale (L) (UV = 2.67). FL% values ranged between 27.8 to 100% and ICF values ranged from 0.97 to 0.99. This study reveals that a large variety of medicinal plant species are of great ethnoveterinary relevance and are used by informants in Haridwar to treat cattle ailments. Further phytochemical and pharmacological studies would be needed to determine the usefulness and safety of the identified plants, allowing communities to use them in a more cost-effective, and safe manner.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84977364","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}

A chloroplast genome rbcL was used in molecular characterization and it revealed the phylogeny and evolutionary affinities of V. inermis with the outgroups of the family through BLAST search based on Neighbor-Joining (NJ) analysis. The free radical scavenging potential of various extracts of V. inermis was observed at different concentrations (20, 40, 60, 80 and 100 μg/mL) in DPPH and ABTS in vitro models. Ascorbic acid (DPPH) and Trolox (ABTS) were used as standard. In DPPH assay, among the different extracts (hexane, chloroform, acetone, ethanol, methanol and water) tested, methanol showed maximum scavenging activity with the IC50 value of 28.33μg/mL followed by acetone with the IC50 value of 31.937μg/mL. The other extracts, ethanol and water extracts showed moderate activity with the IC 50 value of 82.558 μg/mL and 81.758μg/mL; chloroform and hexane showed very lower antioxidant activity and the IC50 values are 518.776μg/mL, 1066.16μg/mL accordingly. In ABTS assay, methanol was observed as a highly active extracts with the IC50 value of 70.196μg/mL followed by ethanol extract (103.078μg/mL). The results showed that the methanol extract exhibits strong antioxidant activity in DPPH and ABTS assays. The scavenging efficiency showed dose dependent increase in concentration absorption compared to Ascorbic acid and Trolox. Our findings provide the molecular identification and evidence for the potential of Volkameria inermis as a source of natural antioxidants.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83321480","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}

It has been used for centuries as a medical preparation and has a variety of roles because of its varied chemical composition. In vitro culture is a useful tool for both multiplication and study of important secondary metabolites. The present study was aimed to develop an effective and reproducible protocol for callus induction and indirect plant regeneration of Ruta graveolens (L.) by using leaf explants and to analyze chemical components present in different extracts of Ruta graveolens. The leaf explants were cultured on MS medium augmented with different combinations and concentrations of auxins and cytokinins for callus induction, shoot multiplication and rooting. The optimum plant growth regulator concentration for callus induction, shoot multiplication and root formation was recorded in MSM+2,4-D(1.5mg/L)+NAA(1.5 mg/L), MSM+ BAP (1.5mg/L) +IBA (1.0 mg/L) and half strength MSM+IBA(0.50 mg/L) respectively. The rooted Plantlets were successfully acclimatized and established in earthen pots. The leaves, stem, roots and callus of Ruta graveolens were extracted by using Acetone and Ethyl acetate solvents followed by volatile compound analysis using GC-MS. The phytochemical assay showed that extracts of Ruta graveolens contain various phytoconstituents having potential bioactivity. The major compounds found were 1, 3-Dioxolane-4-propanol, 2, 2-Dimetheyl-, kokusaginine, Bergaptene, 2 Undecanone, 3-Hexene-2-one, Alpha, - 1- Arabinopyranose, 1, 2:3,4-bis-o, and 1- (1,3-Benzodioxol-5-ylmethyl)-3-Nitro-1 which might be primarily contributing in the biological activity of the plant.

Chalk glands are abundant on lower surface and sparse on upper surface of leaf. Chalk glands are approximately hemispherical glands with oval or almost circular outline. It is composed of 8 cells arranged in two circles – central circle of 4 secretory cells and outer circle of 4 adjoining cells. Each secretory cell has depression which corresponds to pore. Each gland is surrounded by 4 subsidiary cells. No significant difference in the structure of chalk glands in both species was noticed. Chalk glands occupy three different positions with regard to epidermal cells –at the same level of the epidermis, slightly sunken in the epidermis and slightly raised above the epidermis. Common elements found in EDAX analysis of all chalk glands are carbon, oxygen, magnesium, sulphur, potassium and calcium. Differences in the presence of elements silicon, chlorine, aluminium, sodium, phosphorus were observed. The presence of significant amount of calcium in chalk glands and their dried deposits and absence of sodium and chlorine from dried deposits and even in some chalk glands appealed to use the term ‘Chalk gland’ instead of ‘Salt gland’ in Plumbago.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91400133","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}

From this observation, the concept of protocol standardization for zygotic embryo culture of this plant was originated. Zygotic embryo culture was proved an efficient in vitro multiplication system of N. oleander. The maximum germination percentage (96%) of zygotic embryos was observed on ¼ MS medium with 15 gm/L sucrose, whereas the best growth medium was optimized as ½ B5 with same sucrose concentration. The second part of this study was aimed to find out the cardiac glycoside accumulation pattern in both in vitro and acclimatized plants. For this purpose, one-month-old in vitro plantlets and acclimatized plants were subjected to LC-MS analysis and 09 cardiac glycosides were detected and quantified in both the systems. Most of the cardiac glycosides including odoroside A (32.71 mg/gm DW), odoroside H (4.69 mg/gm DW) and oleandrin (0.52 mg/gm DW) were found to be accumulated at maximum level within in vitro plantlets. CG 840b (1.89 mg/gm DW) is the only cardiac glycoside, which was maximally accumulated in acclimatized plants. From this study, it can be concluded that, zygotic embryo culture is a better choice for in vitro multiplication of N. oleander when compared to matured seeds and in vitro grown plantlets of this species favor cardiac glycosides biosynthesis in comparison to acclimatized plants. Therefore, all future research on the enrichment of cardiac glycosides from this plant may be conducted on zygotic embryos derived in vitro grown plantlets or cultures.","PeriodicalId":10828,"journal":{"name":"Current Botany","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84368555","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}
