H(+)-translocating inorganic pyrophosphatases (H(+)-PPase) were recognized as the original energy donors in the development of plants. A large number of researchers have shown that H(+)-PPase could be an early-originated protein that participated in many important biochemical and physiological processes. In this study we cloned 14 novel sequences from 7 eremophytes: Sophora alopecuroid (Sa), Gl...

ماهیان بخشی از ذخایر باارزش زیستی دریای خزر محسوب شده و نقش مهمی در تأمین غذای انسانها بالأخص جوامع بومی و محلی دارند. طی سالیان اخیر فعالیتهای طبیعی و انسان‌ساخت توانسته بخش زیادی از آلایندههای فلزات سنگین را وارد این اکوسیستم آبی نماید. این آلاینده‌ها قادرند که بهتدریج توسط آبزیان جذب و در پیکره زنجیره غذایی بالا روند. تحقیق حاضر غلظت فلزات آرسنیک و آهن را در بافتهای عضله و پوست ماهی کیل...
Abstract This study was conducted to investigate the possibility of population forming of Oncorhynchus mykiss in competition with Salmo caspius on the southern shores of the Caspian Sea in Mazandaran province, Iran. One hundred fish specimens were collected seasonally from commercial purse seine from October 2017 to April 2018. Brown trout diet was analyzed and a total of 90 individuals belo...
