Comparative anatomy and pollen morphology of two endemic Noccaea species (Brassicaceae) and their taxonomic significance

This study was conducted for extensive and systemic investigation of anatomical, palynological and seed morphological properties of two endemic Noccaea species, naturally growing in Turkey. Independent sample T-test and box plot were carried out using quantitative characters of the studied species. The anatomical results showed that the species had similar characteristics, though there were significant differences in root cortex cells and trachea; stem epidermis, cortex cell and endodermis; leaf upper and lower epidermis, lower cuticle, mesophyll and palisade parenchyma.  Pollen grains of two endemic species were observed as radially symmetric, isopolar, with tricolpate aperture, prolate pollen shape and had small size. Pollen surface ornamentation was micro-reticulate in both species. Considering palynological characters, equatorial axis, AMB exine and intine have taxonomic importance. Seeds of N. birolmutlui were ovate to orbicular in shape and orange-brown in color, with colliculate ornamentation; however, the seeds of N. camlikensis were ovate to oblong in shape and brown and shiny in color, with colliculate-reticulate ornamentation

Antioxidant Properties of Freshly Collected Leaves of Diplotaxis tenuifolia (L.) DC

Diplotaxis tenuifolia (L.) DC, recognized by its common name of wild rocket, has a notable role within the Brassicaceae family. The leaves of this plant offer a unique flavor that enhances culinary preparations, alongside their influence on improvement in overall human well-being due to their nutrient and bioactive compound content. Wild rocket possesses a wide range of antioxidants, incorporating vitamins such as C and E, along with carotenoids, glucosinolates, and flavonoids. The objective of this study was to assess the antioxidant properties of the fresh leaves from three wild rocket hybrids: Marte F1, Venere F1, and T&T F1. Using an 80% acetone solution as the solvent, powdered plant material was subjected to a 3-h extraction period at a ratio of 1:10 (plant material/solvent). After the extraction process, the antioxidant properties of the extracts were assessed spectrophotometrically using four distinct assays: DPPH⦁, ferric reducing power (FRP), in vitro phosphomolybdenum total antioxidant capacity (TAC), and cupric reducing antioxidant capacity (CUPRAC). Phytochemical analyses disclosed a variation in the quencher assay results among hybrids, ranging from 5.42 to 6.19 μmol Trolox/g. Nevertheless, the statistical analysis indicated a lack of statistically significant differences among the hybrids within this specific quencher assay. Similarly, no statistically significant differences were found among the samples in relation to the TAC results. The T&T hybrid achieved the highest results in both the FRP and the CUPRAC assays (2.79 mg/g AAE and 17.73 mg/g AAE respectively). Notably, there were no statistical differences observed between the T&T and Venere hybrids. However, both the T&T and Venere hybrids exhibited statistically significant differences when compared to the Marte hybrid. The overall results showed variations among the chosen hybrids regarding their antioxidant properties, while indicating the potential of fertilization in the enhancement of the bioactive compound profile and biological activity

SUMMARY AND CONCLUSION: Herbal medicines are found to be effective in treatment of various ailments but the major lacuna is lack of proper scientific validation. Hence the present study is aimed at investigating the selected plant Erythrina variegata Linn., for the Polycystic Ovarian Disease. The plant Erythrina variegata Linn., belonging the family Fabaceae, is claimed to be useful for Emmenagogue, but the claim has not been scientifically validated. Authentication of the plant material plays a key role in Pharmacognostical studies. The plant Erythrina variegata Linn., was collected from Karur district, Pillapalayam village and Authenticated by Prof. P. Jayaraman, Ph.D., Plant Anatomy Research Centre, Chennai. The parameters studied were Macroscopy, Microscopy, Powder microscopy, Leaf constants, Linear measurements, Histochemical studies and Physiochemical constants to establish data for proper authentication and detection of adulterants. The qualitative and quantitative analysis were carried out to identify inorganic elements present in the plant. The qualitative and quantitative analysis of toxic heavy metals like Cadmium, Arsenic, Lead and Mercury were within the WHO limits and ensure the safety of the drug. In Phytochemical analysis, extraction is the first step involved. The coarse powder was extracted by Petroleum ether, Chloroform, Ethyl acetate and Ethanol by successive solvent extraction by hot percolation method and aqueous extract by cold maceration. The preliminary Phytochemical screening of various extract of the plant have revealed the presence of constituents like alkaloids, flavanoids, steroids and fats & fixed oils. Quantitative estimation of alkaloids, flavonids and phenolics compounds was done. Fluoroscence analysis of powder and extract was done and it did not any fluorescent chromophore. TLC and HPTLC analysis of Ethanolic extract was carried out to identify Phytoconstituents present. In – vitro studies – DPPH assay and Hydrogen peroxide radical Scavenging assay were performed to select the most Bio – active extract. Based on this the ethanol extract was selected for In-vivo studies. Acute toxicity studies revealed that the extract was safe up to the dose of 2000 mg/kg and the LD50 values in the range of 2000 mg/kg. Hence 200 mg/kg and 400 mg/kg was selected for the study. Polycystic Ovarian disease was assessed by Letrazole induced Polycystic Ovarian disease method. The parameters studied were Body weight changes, Food intake, Vaginal exolitative cytology, Blood sugar level, Lipid profile (TC, TGs, LDL, HDL), Reproductive organ weight and Histopathological studies. Ethanolic extracts showed decrease in the elevated level of body weight, food intake, triglycerides, total cholesterol, LDL and reproductive organ weight and increase in the HDL level. All the parameters revealed the effective role of ethanolic extract in Polycystic Ovarian disease activity which was comparable to the standard. In the study of Polycystic Ovarian disease activity the Ethanolic extract shows significant activity in both In – vitro and In – vivo models. Ethanolic extract of Erythrina variegata Linn., showed many beneficial effects similar to standard drug in treating PCOS condition and inducing ovulation. These effects may be ascribed to its multiple pharmacological activities like estrogenic, antihyperlipidemic, antioxidant and hypoglycemic effects which could be useful in managing PCOS condition and prevent ovarian cell dysfunction, ovulation and thereby improving fertility. Together broad spectrum biological effects of Ethanolic extract of Erythrina variegata Linn., make it a promising drug for treating clinical and pathological abnormalities in PCOD condition. Isolation of compound using Column Chromatography was carried out to elute the individual compounds. They were further subjected for spectral analysis like IR and GC – MS. The isolated compound was proposed to be N-Hexadecanoic acid and Erucic acid. Survey of Polycystic Ovarian Disease among the girls students and working women in the age group 17-34 years was done , to collect the data and statistical measurements done. The research on all of these aspects of PCOD will inform the public about how PCOD can affect them and their loved ones

Pre-breeding - fishing in the gene pool

This Book of Abstracts “Pre-breeding – fishing in the gene pool” includes the summary for each of the invited keynotes, volunteer talks and posters presented at the EUCARPIA Genetic Resources Section Meeting held at the campus of the Swedish University of Agricultural Sciences (SLU) in Alnarp from 10 to 13 June 2013. This meeting gathers various members of the gene bank community of practice as well as users of the genetic resources from all around Europe and the World. The selected overall theme for the meeting is “Pre-Breeding - fishing in the gene pool” because we want to discuss how we better can use our genetic resources to cope with the issues being faced today by humankind. Germplasm enhancement or pre-breeding refers to the transfer or introgression of genes and gene combinations from non-adapted sources into breeding materials. It should therefore be understood as an early component of sustainable plant breeding that deals with identifying a useful character, capturing its genetic diversity, and putting genes into usable forms that will be further used in population improvement or line development. During this gathering we will address the role of genomics for adding value to genebank holdings and facilitating their management, the conservation and use of crop wild relatives in germplasm enhancement, how plant genetic resources serve multifunctional agriculture and what traits gene banks can offer to address climate change. We will also learn more about the role of gene banks for ensuring food and feed, and how genetic diversity contributes to human health and nutrition. Last but not least we will assess how genetic endowments can be used in crop breeding to reduce agriculture´s footprints, as well as on the management of intellectual property for plant genetic resources, particularly in the light of increasing public-private partnerships on pre-breeding. The book content follows the order indicated in the program of this conference
