اسفناج یکی از سبزیجات برگی مهم در اکثر کشورها بوده و به علت این که دارای بیشترین تعداد کلروپلاست می باشد و همچنین تعداد ژنوم کلروپلاستی در یک کلروپلاست آن بسیار زیاد است یکی از قدیمی ترین گیاهان مدل برای مطالعه کلروپلاست است. لذا بهینه سازی باززایی این گیاه ضروری است. این پژوهش به منظور بهینه سازی کالوس زایی و باززایی گیاه اسفناج، با استفاده از سه ریزنمونه برگ، هیپوکوتیل و کوتیلدون در سه آزمای...
Spinach (Spinacia oleracea L.) is an economically important green leafy vegetable crop. In this study, we performed deep transcriptome sequencing for nine spinach accessions: three from cultivated S. oleracea, three from wild S. turkestanica and three from wild S. tetrandra. A total of approximately 100 million high-quality reads were generated, which were de novo assembled into 72,151 unigenes...
A wide-ranging examination of plastid (pt)DNA sequence homologies within higher plant nuclear genomes (promiscuous DNA) was undertaken. Digestion with methylation-sensitive restriction enzymes and Southern analysis was used to distinguish plastid and nuclear DNA in order to assess the extent of variability of promiscuous sequences within and between plant species. Some species, such as Gossypiu...
Studies were conducted to characterize ATPase activity associated with purified chloroplast inner envelope preparations from spinach (Spinacea oleracea L.) plants. Comparison of free Mg(2+) and Mg.ATP complex effects on ATPase activity revealed that any Mg(2+) stimulation of activity was likely a function of the use of the Mg.ATP complex as a substrate by the enzyme; free Mg(2+) may be inhibito...
Recently, 6-(2-naphthyl)-2, 3-dihydro-as-triazine-3-thione (NDTT) was synthesized in laboratory and used successfully for the spectrophotometric determination of nanogram levels of Cu2+ in aqueous solution. This reagent forms a specific red complex with Cu2+ ions after the extraction by chloroform at alkaline pH. The absorption of the complex in the UV region (313 nm) is about 8 times as strong...
