The successful clinical management of spinal cord injury (SCI) is still a unmet medical need. Despite advances in novel therapeutics, the multifactorial etiology of SCI still poses significant challenge to the mankind. Thus, in the present study, we intend to scrutinize the protective effect of Boldine (BOL), an alkaloid obtained from the boldo tree against experimental spinal cord injury. The effect of BOL was investigated on locomotor function of rats with various biomarkers of oxidative stress (MDA, SOD and GSH), inflammation (TNF-α, IL-1β and IL-6), and apoptosis. Results suggest that BOL showed improvement in locomotor function (on BBB scale) of rats with does-dependent reduction in oxidative stress and inflammation. It also reduces neuronal apoptosis in flow cytometry experiment. The study successfully demonstrated the possible clinical utility of BOL against SCI.

Pomegranate (Punica granatum L.) is a widely used fruit, which contains several interesting bioactive compounds and possess health-promoting properties. Seeing the importance of this fruit, it is crucial to study its quality characteristics. Hence, in the current study, we assessed phenolic content, flavonoid content and antioxidant activity of different plant parts (leaves, rind and arils) of two pomegranate cultivars (Kesar and Ganesh). The analysis of phytochemical constituents in the cultivars revealed that, the content of phenolics ranged from 49.3 to 602 mg TAE/g plant material and the content of flavonoids ranged from 0.27 to 18.8 mg RE/g plant material. The maximum amount of phenolics and flavonoids was observed in the rind extracts as compared to the leaves and arils in both the cultivars. On the other hand, the antioxidant activity determined by different antioxidant models exhibited various degrees of antioxidant activity in different plant parts of the cultivars and was found to be highest in rind and aril extracts than that of leaves. Among the solvents methanol and ethanol gave highest extraction yields as compared to water and acetone. Total phenolics and flavonoids were significantly different with methanol and ethanol being the most efficient solvent and acetone being the least efficient one. Correlation between the antioxidant activity and phenolics and flavonoid content was found to be significant. Thus the results strongly indicated that there were significant differences between pomegranate cultivars. Generally the cultivar Ganesh has higher antioxidant activity as well as total phenolics and flavonoid content in comparison to Kesar.

Clausena (Rutaceae) is only one genus native both to the Monsoon region and to tropical and subtropical Africa in the subfamily Aurantioideae. The most distinctive morphological character in this genus is the gynophore supporting the ovary and the morphology of pistil can help to define the natural groups of species. Based on the morphological data of flowers and molecular phylogeny of ITS, trnL-F and atpB-rbcL, the taxonomic problems of some species in China are resolved here. The species C. lenis has a separate status in the genus Clausena, then C. lansium stands apart from other species except C. lenis; the species status of five species, C. odorata, C. vestita, C. dunniana, C. emarginata, and C. anisum-olens are restated.

Low temperature plasma (LTP) exerted beneficial effects on seed germination and crop growth. With application of LTP on seed germination of Platycodon grandiflorum, germination indexes and physiological parameters and transcriptome profile were investigated in this experiment. The results showed the seed germination rate and germinating potential of Platycodon grandiflorum in LTP increased by 24.7% and 30.7% comparing to CK respectively (p < 0.05). The SOD and CAT activity of the seed sprouts increased by 26.78% and 12.41% comparing to CK. Transcriptome results showed that 14342 up-regulated and 4366 down-regulated different expressing genes (DEGs) at LTP and CK. A considerable number of DEGs related to the plant hormone signal transduction, peroxisome, oxidative phosphorylation, starch and surose in response to low temperature plasma were identified in this study. The transcriptomic gene expression profiles present a valuable genomic tool to the molecular mechanisms of Platycodon grandiflorum seed germination underlying low temperature plasma. which can provide theoretical basis and practical guidance for cultivation and planting of Platycodon grandiflorum.

Anthocyanins are water-soluble pigments responsible for red, pink, purple or blue coloration in the flesh and/or skin of apple fruit. Since consumers prefer anthocyanin rich fruits due to their health benefits, anthocyanin content is an important trait for marketability of apples. Synthesis and accumulation of anthocyanins are controlled by environmental and genetic factors such as transcription factors (TFs). Two-repeat (R2R3) MYB TFs are involved in the regulation of anthocyanin biosynthesis in plants. In this study, the expression of the MdMYBA and MdMYB3 genes encoding R2R3 type MYB TFs were analyzed in apple cultivars with fruit skin color from green to dark red at different growth stages. Fruit samples were collected from “Scarlet Spur”, “Galaxy Gala”, Golden Delicious” “Granny Smith” apple cultivars with dark red, light red, yellow and green fruits, respectively, at four different time periods after full-bloom. Total RNA was isolated from the peel of the collected fruits and the expression of the MdMYBA and MdMYB3 genes was analyzed by real-time RT-PCR. The expression of the MdMYBA gene started to increase at 92 DAFB and thereafter in red-skin apples; however, no expression was observed at any time points in yellow or green-skin apple cultivars. On the other hand, the MdMYB3 gene was expressed in red-skin and yellow-skin apple cultivars starting at 55 DAFB, but no expression was observed in green apple cultivar at any time of fruit maturation. The expression levels of the MdMYBA and MdMYB3 genes varied in apple fruits with different skin coloration indicating that they play a role regulation of the anthocyanin biosynthesis in apple cultivars during fruit maturation.

Encroachment of woody plants into grasslands and subsequent brush management are among the most prominent changes occurring in arid and semiarid ecosystems over the past century. The reduced number of farms, the abandonment of marginal land and the decline of traditional farming practices have led to encroachment of the woody and shrubby components into grasslands. This phenomenon, specifically in the Mediterranean region, which is followed by a reduction in herbage production, biodiversity and increased fire risk, is generally considered an undesirable process. Sarcopoterium spinosum has had great success in the eastern Mediterranean as a colonizer and dominant bush species on a wide variety of sites and climatic conditions. In the Mediterranean dehesa, the high magnitude and intensity of shrub encroachment effects on pastures and on tree production were shown to be dependent on temporal variation. Accordingly, there are attempts to transform shrublands into grassland-woodland matrices by using different techniques. The main management interventions that are commonly used include grazing, woodcutting, shrub control with herbicides or by mechanical means, amelioration of plant mineral deficits in the soil, and fire. However, the effects of these various treatments on the shrubs under diverse environmental conditions were found to be largely context-specific. As such, the most efficient option for suppressing encroachment of shrubs is combining different interventions. Appropriate management of grazing, periodic control of the shrub component, and occasional soil nutrient amelioration can lead to the development of attractive open woodland with a productive herbaceous understory that provides a wider range of ecological services.

Understanding genetic diversity in target populations is of great importance in breeding and a prerequisite for association mapping of traits. In this study, 57 cross species simple sequence repeat (SSR) markers were screened for amplification in China aster. Twenty six polymorphic markers were used to estimate the genetic diversity in forty two China aster genotypes. The observed and expected heterozygosities within the genotypes were ranged from 0.00 to 0.80 and 0.17 to 0.50, respectively. Weighted Neighbor Joining method, grouped China aster genotypes into five major clusters which coincided for morphological traits mostly flower color and form, but not correlated for their geographical locations. The results suggested that, population may be useful for the genome-wide marker–trait association mapping. These set of cross species transferable SSR markers would enable the application of the SSR technique in China aster crop improvement.

Plant-derived substances have been shown to affect potential targets in inflammatory diseases. We have previously purified from the desert plant Achillea fragrantissima, a sesquiterpene lactone named achillolide A, and demonstrated its anti-inflammatory activities in cultured brain macrophages named microglial cells. In the present study, we further investigated achillolide A in alleviating atopic dermatitis, a chronic and recurring inflammatory skin disease. We investigated achillolide A for its in vivo anti-inflammatory activity using the oxazolone model of atopic dermatitis in mice, in which oxazolone induces ear swelling. Our results show that mice treated with achillolide A showed a significant decrease in the oxazolone-induced ear swelling. Since macrophages are inflammatory cells that play a pivotal role in the pathogenesis of atopic dermatitis, the anti-inflammatory effects of achillolide A were also studied in spleen cells. We demonstrated that achillolide A reduced the levels of LPS-induced inflammatory cytokines IL-2, IL-6, TNFα, IFNγ and IL-12 that were secreted from cultured splenocytes. These data suggest that achillolide A should be considered for further research in treating atopic dermatitis.

Tchihatchewia isatidea Boiss (Brassicaceae) is known among the public as “Reddish Bride”, “Paint and Bridal Flower”. Flower parts are used for painting and flowering branches for treatment of cough. In this study, anticancer properties of water, ethanol and methanol extracts of Tchihatchewia isatidea flower parts were investigated against human breast (MCF-7), human colon (HCT-116) and human prostate (LNCaP) cancer cell lines. Changes in the viability of cancer cells were detected by utilizing 3- (4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide (MTT) method. Studies have shown that there is a statistically significant decrease in the cell viability of human breast cancer (MCF-7), colon (HCT-116) and prostate (LNCaP) cancer cells when extracts of T. isatidea water, ethanol and methanol are used.
