Rhizophagus irregularis regulates antioxidant activity and gene expression under cadmium toxicity in Medicago sativa
Cadmium (Cd) is a phytotoxic heavy metal (HM) that can induce generation of reactive oxygen species (ROS). Arbuscular mycorrhizal fungi (AMF) are considered as bio-ameliorators that help to mitigate HM-derived oxidative stress. The objective of this study was to assess AM fungus Rhizophagus irregularis on changes in enzymatic activity and transcription of antioxidants of Medicago sativa to Cd s...
متن کاملColonization of Phaseolus vulgaris nodules by Agrobacterium-like strains.
Non-nodulating Agrobacterium-like strains identified among root nodule isolates of common bean were labeled with gusA, a reporter gene encoding beta-glucuronidase (GUS). Bean plants were then co-inoculated with an infective Rhizobium strain and labeled transconjugants of Agrobacterium-like strains. Blue staining of nodules showed that Agrobacterium-like strains were able to colonize these symbi...
متن کاملIntra and Inter-Spore Variability in Rhizophagus irregularis AOX Gene
Arbuscular mycorrhizal fungi (AMF) are root-inhabiting fungi that form mutualistic symbioses with their host plants. AMF symbiosis improves nutrient uptake and buffers the plant against a diversity of stresses. Rhizophagus irregularis is one of the most widespread AMF species in the world, and its application in agricultural systems for yield improvement has increased over the last years. Still...
متن کاملنقش قارچ Rhizophagus irregularis در تعدیل جذب سرب توسط آفتابگردان
آلودگی خاک با فلزات سنگین از جمله سرب یکی از مشکلات زیست محیطی عمده در جوامع بشری است که علاوه بر کاهش عملکرد و کیفیت محصول، پایداری تولیدات کشاورزی را دچار مخاطره نموده و سلامتی موجودات زنده را به خطر میاندازد. در برخی موارد مشاهده شده که قارچ میکوریز با غیرمتحرک کردن فلزات سمی در خاک و اندام‌های خود، مانع از ورود آنها به ریشه شده و یا این که با غیرمتحرک کردن آنها در داخل ریشه، مانع از حرکت...
متن کاملGlycosidases of Phaseolus vulgaris
The enzymes, cr-galactosidase, P-galactosidase, a-mannosidase, P-glucosidase, and p-acetylglucosaminidase, have been purified from the germinating seeds of Phaseolus vulgaris. All five enzymes have been simultaneously isolated in a highly active form. The pH optimum, K,,,, and energy of activation of each glycosidase for the reaction of hydrolysis of the appropriate P-nitrophenyl glycoside have...
