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...
Excision of spinach (Spinacia oleracea L.) leaves had no effect on photosynthetic rates, but altered normal carbon partitioning to favor increased formation of starch and decreased formation of sucrose. The changes were evident within 2 hours after excision. Concurrently, leaf fructose-2,6-bisphosphate content increased about 5-fold (from 0.1 to 0.5 nanomoles per gram fresh weight). The activit...
In the study, a series of twelve ring-substituted 4-hydroxy-1H-quinolin-2-one derivatives were prepared. The procedures for synthesis of the compounds are presented. The compounds were analyzed using RP-HPLC to determine lipophilicity and tested for their photosynthesis-inhibiting activity using spinach (Spinacia oleracea L.) chloroplasts. All the synthesized compounds were also evaluated for a...
The influence of interleukin 4 (IL-4) on antibody titer in serum and spleen culture supernatant in mice immunized with spinach (Spinacia oleracea L.) Rubisco was investigated. Therefore, we boosted one mouse additionally to the antigen with recombinant mouse IL-4. We found that the Rubisco-specific antibody titer in serum as well as in spleen cell culture supernatant was significantly enhanced ...
Radish (Raphanus sativus L. cv. Cherriette), lettuce (Lactuca sativa L. cv. Waldmann's Green), and spinach (Spinacea oleracea L. cv. Nordic IV) plants were grown under 660-nm red light-emitting diodes (LEDs) and were compared at equal photosynthetic photon flux (PPF) with either plants grown under cool-white fluorescent lamps (CWF) or red LEDs supplemented with 10% (30 micromoles m-2 s-1) blue ...
