As ROS have the potential to cause oxidative damage by reacting with biomolecules, research on ROS has concentrated on the oxidative damage that results from exposure to environmental stresses and on the role of ROS in defence against pathogens. However, more recently, it has become apparent that ROS also have important roles as signalling molecules. A complex network of enzymatic and small molecule antioxidants controls the concentration of ROS and repairs oxidative damage, and research is revealing t 410 0$aBiological Sciences Series 606 $aAntioxidants$xPhysiological effect 606 $aActive oxygen$xPhysiological effect 606 $aPlants$xMetabolism 615 0$aAntioxidants$xPhysiological effect. 615 0$aActive oxygen$xPhysiological effect. 615 0$aPlants$xMetabolism. 676 $a572.42 676 $a572/.42 701 $aSmirnoff$b N$0990662 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996205536603316 996 $aAntioxidants and reactive oxygen species in plants$92266776 997 $aUNISA LEADER 04307oam 22005414a 450 001 9910793663503321 005 20191208030011.0 010 $a2-7637-4366-8 035 $a(CKB)4100000008603123 035 $a(MiAaPQ)EBC5802223 035 $a(OCoLC)1108573695 035 $a(MdBmJHUP)muse78539 035 $a(PPN)238407306 035 $a(EXLCZ)994100000008603123 100 $a20191203d2019 uy 0 101 0 $afre 135 $aurcnu|||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aÉcritures francophones.

L'esclavage, la colonisation, les dictatures et la violence sont au nombre des themes abordes, formant le tableau d'une litterature du desenchantement. Les articles relevent l'adoption d'une rhetorique qui accorde une grande place a? l'ironie, a? l'humour et aux jeux discursifs. Ce rapport ludique a? la langue et au lecteur permettrait aux ecrivains de tourner en ridicule certains discours sociaux, de subvertir l'ordre collectif et ainsi, de contrebalancer leur pessimisme face au monde. Les articles convoquent un corpus d'oeuvres varie, parcourant quatre aires geographiques (Afrique, Antilles, Proche-Orient et ocean Indien), divers genres litteraires (roman, thea?tre, poesie et essai), analysant des auteurs classiques (Aime Cesaire, E?douard Glissant et Cheikh Hamidou Kane) autant que des ecrivains peu etudies jusqu'a? ce jour (Salah Stetie, Shenaz Patel et E?liane Kodjo). 410 0$aRecherches francophones (Quebec, Quebec) ;$v4. 606 $aSocial problems in literature 606 $aIrony in literature 606 $aFrench literature$zFrench-speaking countries$xHistory and criticism 608 $aElectronic books. 615 0$aSocial problems in literature. 615 0$aIrony in literature. 615 0$aFrench literature$xHistory and criticism. 676 $a840.9896 702 $aSevigny-Co?te$b Yasmina 702 $aLiljesthro?m$b Valeria 712 02$aUniversite Laval.$bChaire de recherche en litteratures africaines et francophonie, 801 0$bMdBmJHUP 801 1$bMdBmJHUP 906 $aBOOK 912 $a9910793663503321 996 $aÉcritures francophones.
