Intra 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...

نقش 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...

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...
