Aspergillus fumigatus is a life-threatening and increasingly frequent pathogen of the immunocompromised. Like other filamentous fungi A. fumigatus grows in a highly polar manner, adding new cell wall to the apical region of hyphae. mAbs were raised against isolated A. fumigatus cell walls. Fifteen antibodies bound reproducibly to isolated cell walls in ELISAs and to the walls of intact cells in...
Six inbred lines of Zea mays expressing different soluble (cytosolic) malate dehydrogenase (sMDH) zymogram phenotypes were analyzed genetically. sMDH was found to be coded for by unlinked duplicated loci in four of these inbred lines. The remaining two lines were found not to possess these duplicated loci. Furthermore, the duplicated loci, sMdh1 and sMdh2, have been found to be located on diffe...
سابقه و هدف: بروز تنش خشکی سبب ایجاد اختلالات متابولیسمی در سلول‌های گیاهی می‌گردد که می‌توان به افزایش تولید گونه‌های فعال اکسیژن به‌عنوان یکی از عوامل اصلی اختلالات متابولیسمی سلول اشاره کرد. گیاهان برای مقابله با تنش اکسیداتیو ایجاد شده، دارای سیستم دفاعی با کارایی بالایی هستند که می‌تواند رادیکال‌های آزاد را از بین برده و یا خنثی کنند. بنابراین در شرایط تنش خشکی، فعالیت‌های بالای آنزیم‌های ...
Neuronal activity influences protein synthesis and neuronal growth. Availability of nutrients, especially leucine and arginine, regulates the mammalian target of rapamycin (mTOR) pathway that controls cell growth. We show that NMDA receptor activation markedly reduces arginine transport by decreasing surface expression of the cationic amino acid transporters (CAT) 1 and 3. Depletion of CAT1 and...
