گندم منبع اولیه ی تأمین غذای انسان، دام، طیور و ماده ی اولیه کارخانه های صنعتی است. قارچ های بیماریزای متعددی در گیاه گندم ایجاد بیماری می نمایند، با توجه به اهمیت این گیاه و بیماری های قارچی منتقل شونده همراه بذر آن در سال های 1390 و 1391 مبادرت به جمع آوری نمونه های بذر و شناسایی قارچ های همراه آن در سطح استان گردید. برای جداسازی قارچ های همراه بذر از 5 روش آزمایشگاهی: کشت روی محیط سیب زمینی/...
Extensive fortnightly surveys were undertaken in major rice growing districts of Jammu division to study cultural and morphological variability amongst the isolates brown leaf spot disease causing fungus (Bipolaris oryzae). Based on severity 24 (BO1 BO24) divided into three groups (I, II III). Group ‘I’ comprised 11 with values between 51.22-67.44% categorized under highly virulent group ‘II’ 4...
Ophiobolin A (OP-A), a fungal sesterterpene from Bipolaris oryzae, was recently shown to have anti-glioma activity. We show here that OP-A induces paraptosis-like cell death accompanied by dilation of the endoplasmic reticulum (ER) in glioma cells, and that CHOP-mediated ER stress plays a critical role in this process. OP-A-induced ER-derived dilation and cell death were found to be independent...
Bee pollen, which is filled into the cells of honeycomb by honeybees to use in nutrition, enriched with digestive enzymes and organic acids from honey salivary gland secretions honeybees. Lactic acid fermentation takes place comb cell under anaerobic conditions bee bread formed. We have limited knowledge about bacteria yeasts are involved process. Samples collected 8 different beehives same api...
Bipolaris oryzae is a phytopathogenic fungus causing a brown spot disease in rice, and produces substance that strongly perturbs motility and membrane integrities of boar spermatozoa. The substance was isolated from the liquid culture of the fungal strain using extraction and a multi-step semi-preparative HPLC procedures. Based on the results of mass spectrometric and 2D NMR techniques, the bio...
