The role of phenolic compounds in growth improvement of cultured tobacco cells after exposure to 2-D clinorotation
Previous studies have confirmed that the growth and development of plants are entirely dependent on the gravitational acceleration of the Earth. So far, most of the studies on the plant response to the Earth gravity have focused on the geotropism of root tip of higher plants<span lang="AR-SA" dir="RTL...
متن کاملrisk taking in english to persian translation process by novice iranian translators
این پژوهش به بررسی ریسک پذیری مترجمان تازه کار در طی فرآیند ترجمه از زبان انگلیسی به فارسی می پردازد. پژوهش درباره مترجمان به عنوان اولین خواننده متن مبدا از اهمیت به سزایی برخوردار است. مترجمان تازه کار (و حرفه ای) در طی فرآیند ترجمه با مشکلات متعددی روبرو می شوند که باعث عدم اطمینان آنها از متن ترجمه شده می شود. با توجه به اینکه عدم اطمینان به انجام ریسک منتهی می شود، هدف این پژوهش بررسی کیفی...
Sulfate transport in cultured tobacco cells.
Sulfate transport by tobacco (Nicotiana tabacum L. var. Xanthi) cells cultured on either l-cysteine or sulfate as a sole sulfur source was measured. The transport rate on either sulfur source was low during pre-exponential growth, increased during exponential growth, and was maximal in late exponential cells. The initial increase in transport rate was correlated with a decline in the intracellu...
متن کاملCysteine metabolism in cultured tobacco cells.
Transported l-[(35)S]cysteine was rapidly metabolized by cultured tobacco cells when supplied to the cells at 0.02 millimolar or 0.5 millimolar. The internal cysteine pool was expandable to approximately 2400 nmoles per gram fresh weight.The (35)S label derived from cysteine was found in several metabolites. The amount of label in glutathione and sulfate was directly proportional to the interna...
متن کاملAre 'Pathogenesis-related' Proteins Involved in Acquired Systemic Resistance of Tobacco Plants to Tobacco Mosaic Virus
Four host-coded 'pathogenesis-related' proteins accumulate systemically in locallesion-forming varieties of tobacco after infection with tobacco mosaic virus. It has been suggested that they are involved in the acquired systemic resistance of plants to a second inoculation. Pathogenesis-related protein concentration and amount of resistance (reduction in size and number of lesions formed in the...
