| 1 | Protective effect of capsaicin against methyl methanesulphonate induced toxicity in the third instar larvae of transgenic Drosophila melanogaster(hsp70-lacZ)Bg9显示文摘Capsaicin(trans-8-methyl-N-vanillyl-6-nonenamide) is the main component in hot peppers, including red chili peppers, alapenos, and habanero, belonging to the genus Capsicum. Capsaicin is a potent antioxidant that interferes with free radical activities. In the present study, the possible protective effect of capsaicin was studied against methyl methanesulphonate(MMS) induced toxicity in third instar larvae of transgenic Drosophila melanogaster(hsp70-lacZ)Bg^9. The third instar was allowed to feed on the diet having different doses of capsaicin and MMS separately and in combination. The results suggested that the exposure of third instar larvae to the diet having MMS alone showed significant hsp70 expression as well as tissue DNA and oxidative damage, whereas the larvae feed on the diet having MMS and capsaicin showed a decrease in the toxic effects for 48-h of exposure. In conclusion, capsaicin showed a dose-dependent decrease in the toxic effects induced by MMS in the third instar larvae of transgenic Drosophila melanogaster. | Saba Khanam Ambreen Fatima Rahul Smita Jyoti Fahad Ali Falaq Naz Barkha Shakya Yasir Hasan Siddique | 2017 | Chinese Journal of Natural Medicines2017，15，4： | 1 |
| 2 | Role of foliar spray of plant growth regulators in improving photosynthetic pigments and metabolites in Plantago ovata (Psyllium) under salt stress–A field appraisal显示文摘Salinity is one of the major abiotic factors that limit the growth and productivity of plants.Foliar application of plant growth regulators(PGRs)may help plants ameliorate the negative impacts of salinity.Thus,a field experiment was conducted at the Botanical Garden University of Balochistan,Quetta,to explore the potential role of PGRs,i.e.,moringa leaf extract(MLE;10%),proline(PRO;1μM),salicylic acid(SA;250μM),and thiourea(TU;10 mM)in ameliorating the impacts of salinity(120 mM)on Plantago ovata,an important medicinal plant.Salinity hampered plant photosynthetic pigments and metabolites but elevated oxidative parameters.However,foliar application of PGRs enhanced photosynthetic pigments,including Chl b(21.11%),carotenoids(57.87%)except Chl a,activated the defense mechanisms by restoring and enhancing the metabolites,i.e.,soluble sugars(49.68%),soluble phenolics(33.34%),and proline(31.47%),significantly under salinity stress.Furthermore,foliar supplementation of PGRs under salt stress led to a decrease of about 43.02%and 43.27%in hydrogen peroxide and malondialdehyde content,respectively.Thus,PGRs can be recommended for improved photosynthetic efficiency and metabolite content that can help to get better yield under salt stress,with the best and most effective treatments being those of PRO and MLE to predominately ameliorate the harsh impacts of salinity. | ABDUL SAMAD KANVAL SHAUKAT MAHMOOD-UR-REHMAN ANSARI MEREEN NIZAR NOREEN ZAHRA AMBREEN NAZ HAFIZ MUHAMMAD WALEED IQBAL ALI RAZA VLADAN PESIC IVICA DJALOVIC | 2023 | BIOCELL2023，47，3： | 1 |
