Intra and Inter-Spore Variability in Rhizophagus irregularis AOX Gene

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...

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...

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...

Inter- and intra-individual variability in alpha peak frequency

Converging electrophysiological evidence suggests that the alpha rhythm plays an important and active role in cognitive processing. Here, we systematically studied variability in posterior alpha peak frequency both between and within subjects. We recorded brain activity using MEG in 51 healthy human subjects under three experimental conditions - rest, passive visual stimulation and an N-back wo...
