Induction of pathogenesis-related proteins in tobacco leaves.
The synthesis of pathogenesis-related proteins (PR proteins), induced in tobacco leaves in response to infection with tobacco mosaic virus or treatment with salicylic acid, was studied with in vivo pulse-labeling experiments. PR proteins synthesis began after a lag phase of about 8 hours in leaf discs treated with salicylic acid and after more than 18 hours in those infected with tobacco mosaic...

ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...
15 صفحه اولThe receptor for the fungal elicitor ethylene-inducing xylanase is a member of a resistance-like gene family in tomato.
An ethylene-inducing xylanase (EIX) is a potent elicitor of plant defense responses in specific cultivars of tobacco (Nicotiana tabacum) and tomato (Lycopersicon esculentum). The LeEix locus in tomatoes was characterized by map-based cloning, which led to the identification of a novel gene cluster from which two members (LeEix1 and LeEix2) were isolated. Similar to the tomato Ve resistance gene...
متن کاملBiological function of pathogenesis-related proteins: Four tobacco pathogenesis-related proteins are chitinases.
Four endochitinases (poly[1,4-(N-acetyl-beta-D-glucosaminide)] glycanohydrolase, EC 3.2.1.14) have been purified from leaves of Nicotiana tabacum cv. Samsun NN reacting hypersensitively to tobacco mosaic virus. Two of them are acidic proteins of molecular weights 27,500 and 28,500 and have been identified as 2 of the 10 pathogenesis-related proteins that are known to accumulate in tobacco in re...
متن کاملSynthesis and localization of pathogenesis-related proteins in tobacco.
The PR1 family of pathogenesis-related proteins from tobacco (Nicotiana tabacum L.) leaves is induced by a variety of pathogenic and chemical agents and is associated with resistance to tobacco mosaic virus. The majority of the PR1 proteins did not copurify with mesophyll protoplasts (the major cell type of the leaf) isolated from tobacco mosaic virus-infected N. tabacum cv. Xanthi-nc leaves. H...
