Anatomy of the sporophyte of Anemia phyllitidis var. phyllitidis (Anemiaceae) from a riparian forest (Tucumán, Argentina)

In vivo Synthesis of [C]Dilinoylgalactosylglycerol by Gametophytes of the Fern Anemia phyllitidis

Blue light-grown gametophytes of Anemia phyllitidis were used for the in vivo synthesis of radioactively labeled dilinoylgalactosylglycerol, a potential intermediate in the synthesis of linolenic acid. Optimal yield was obtained by incubating gametophytes with [C]linoleate first for 2 h under anaerobic conditions followed by 46 h under aerobic conditions. As product [C]dilinoylgalactosylglycero...

Incorporation of 5-Bromo-2-deoxyuridine into the Chloroplast DNA of Anemia phyllitidis

As pointed out previously [1 ], 5-bromo-2-deoxyuridine (BUdR) causes significant changes in the ultrastructure of chloroplasts in the prothallia of Anemia phyllitidis. Since natural mutants show comparable modifications in chloroplast structure there is reason to assume an analogous effect at the level of processing of the genetic information. Since chloroplasts are partially autonomous with re...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
