Radical Scavenging and Antimicrobial Properties of Polyphenol Rich Waste Wood Extracts
'MDPI AG', 2020Co-Authors: Smailagic Anita, Ristivojevic Petar, Dimkic Ivica, Pavlovic Tamara, Zagorac, Dragana Dabic´, Veljovic Sonja, Akšic, Milica Fotiric´, Meland Mekjell, Natic MajaAbstract:The main focus of this study is to assess radical scavenging and antimicrobial activities of the 11 wood extracts: oak (Quercus petraea (Matt.) Liebl., Q. robur L., and Q. cerris L.), mulberry (Morus alba L.), myrobalan plum (Prunus cerasifera Ehrh.), black locust (Robinia pseudoacacia L.), and wild cherry (Prunus avium L.). High-performance thin-layer chromatography (HPTLC) provided initial phenolic screening and revealed different chemical patterns among investigated wood extracts. To identify individual compounds with radical scavenging activity DPPH-HPTLC, assay was applied. Gallic acid, ferulic and/or caffeic acids were identified as the compounds with the highest contribution of total radical scavenging activity. Principal component analysis was applied on the data set obtained from HPTLC chromatogram to classify samples based on chemical fingerprints: Quercus spp. formed separate clusters from the other wood samples. The wood extracts were evaluated for their antimicrobial activity against eight representative human and opportunistic pathogens. The lowest minimum inhibitory concentration (MIC) was recorded against Staphylococcus aureus for black locust, cherry and mulberry wood extracts. This work provided simple, low-cost and high-throughput screening of phenolic compounds and assessments of the radical scavenging properties of selected individual metabolites from natural matrix that contributed to scavenge free radicals.publishedVersio

High-resolution mapping and chromosome landing at the root-knot nematode resistance locus Ma from Myrobalan plum using a large-insert BAC DNA library
TAG Theoretical and Applied Genetics, 2004Co-Authors: Michel Claverie, Elisabeth Dirlewanger, Patrick Cosson, Nathalie Bosselut, C. Lecouls, Roger Voisin, Marc Kleinhentz, Bernard Lafargue, Michel Caboche, Paul ChalhoubAbstract:The Ma gene for root-knot nematode (RKN) resistance from Myrobalan plum (Prunus cerasifera L.) confers a complete-spectrum and a heat-stable resistance to Meloidogyne spp., conversely to Mi-1 from tomato, which has a more restricted spectrum and a reduced efficiency at high temperature. This gene was identified from a perennial self-incompatible near-wild rootstock species and lies in cosegregation with the SCAR marker SCAFLP2 on the Prunus linkage group 7 in a 2.3 cM interval between the SCAR SCAL19 and SSR pchgms6 markers. We initiated a map-based cloning of Ma and report here the strategy that rapidly led to fine mapping and direct chromosome landing at the locus. Three pairs of bulks, totaling 90 individuals from half-sibling progenies derived from the Ma-heterozygous resistant accession P.2175, were constructed using mapping data, and saturation of the Ma region was performed by bulked segregant analysis (BSA) of 320 AFLP primer pair combinations. The closest three AFLP markers were transformed into codominant SCARs or CAPS designated SCAFLP3, SCAFLP4 and SCAFLP5. By completing the mapping population up to 1,332 offspring from P.2175, Ma and SCAFLP2 were mapped in a 0.8 cM interval between SCAFLP3 and SCAFLP4. A large-insert bacterial artificial chromosome (BAC) DNA library of P.2175, totaling 30,720 clones with a mean insert size of 145 kb and a 14-15x Prunus haploid genome coverage was constructed and used to land on the Ma spanning interval with few BAC clones. As P.2175 is heterozygous for the gene, we constructed the resistant and susceptible physical contigs by PCR screening of the library with codominant markers. Additional microsatellite markers were then designed from BAC subcloning or BAC end sequencing. In the resistant contig, a single 280 kb BAC clone was shown to carry the Ma gene; this BAC contains two flanking markers on each side of the gene as well as two cosegregating markers. These results should allow future cloning of the Ma gene in this perennial species.

development of microsatellite markers in peach prunus persica l batsch and their use in genetic diversity analysis in peach and sweet cherry prunus avium l
Theoretical and Applied Genetics, 2002Co-Authors: Elisabeth Dirlewanger, P Cosson, M Tavaud, Maria Jose Aranzana, C Poizat, A Zanetto, Pere Arus, F LaigretAbstract:We report the sequence of 41 primer pairs of microsatellites from a CT-enriched genomic library of the peach cultivar 'Merrill O'Henry'. Ten microsatellite-containing clones had sequences similar to plant coding sequences in databases and could be used as markers for known functions. For microsatellites segregating at least in one of the two Prunus F2 progenies analyzed, it was possible to demonstrate Mendelian inheritance. Microsatellite polymorphism was evaluated in 27 peach and 21 sweet cherry cultivars. All primer pairs gave PCR-amplification products on peach and 33 on cherry (80.5%). Six PCR-amplifications revealed several loci (14.6%) in peach and eight (19.5%) in sweet cherry. Among the 33 single-locus microsatellites amplified in peach and sweet cherry, 13 revealed polymorphism both in peach and cherry, 19 were polymorphic only on peach and one was polymorphic only on cherry. The number of alleles per locus ranged from 1 to 9 for peach and from 1 to 6 on sweet cherry with an average of 4.2 and 2.8 in peach and sweet cherry, respectively. Cross-species amplification was tested within the Prunus species: Prunus avium L. (sweet cherry and mazzard), Prunus cerasus L. (sour cherry), Prunus domestica L. (European plum), Prunus amygdalus Batsch. (almond), Prunus armeniaca L. (apricot), Prunus cerasifera Ehrh. (Myrobalan plum). Plants from other genera of the Rosaceae were also tested: Malus (apple) and Fragaria (strawberry), as well as species not belonging to the Rosaceae: Castanea (chestnut tree), Juglans (walnut tree) and Vitis (grapevine). Six microsatellites gave amplification on all the tested species. Among them, one had an amplified region homologous to sequences encoding a MADS-box protein in Malus × domestica. Twelve microsatellites (29.3%) were amplified in all the Rosaceae species tested and 31 (75.6%) were amplified in all the six Prunus species tested. Thirty three (80.5%), 18 (43.9%) and 13 (31.7%) gave amplification on chestnut tree, grapevine and walnut tree, respectively.

For keratinocytes, the expression profiles are for genes encoding HAS1, HAS2, HYAL1, HYAL2, versican, CD44, IL-1α, cox2, TGF-β, AQP3, Laminin5, collagen, type XVII, alpha 1 (COL17A1), integrin alpha-6 (ITGA6), ceramide synthase 3 (CERS3), elongation of very long chain fatty acids protein 1 (ELOVL1), elongation of very long chain fatty acids protein 4 (ELOVL4), filaggrin (FLG), transglutaminase 1 (TGM1), and keratin 1 (KRT1). The expression profiles are provided as bar graphs.

Elsevier, 2018Co-Authors: Kotaro Hara, Takao Someya, Katsura Sano, Yoshimasa Sagane, Toshihiro Watanabe, R.g.s. WijesekaraAbstract:This article describes free radical-scavenging activities of extracts of several plants harvested in Sri Lanka through the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. These plants have traditionally been used in the indigenous systems of medicine in Sri Lanka, such as Ayurveda, as described below.
