بررسی سیستماتیکی secale cereale در ایران
Authors
abstract
چاودار ((secale cereale نوعی غله شناخته شده است که امروزه از جایگاه تثبیت شده ای در جهان به ویژه در شمال اروپا برخوردار است. در این تحقیق ریخت شناسی، تاکسونومی و سیتوتاکسونومی این گیاه در ایران مطالعه گردید. با توجه به بررسی منابع و مطالعه نمونه های جمع آوری شده از سراسر ایران و نمونه های هرباریومی، از نظر تاکسونومیک مشخص شد که دو زیرگونه cereale و ancestrale در ایران وجود دارد و ارزیابی 12 صفت کمی و کیفی و تحلیل فنتیک نیز آن را تایید کرد. از مهمترین صفات جهت جدا کردن این دو زیرگونه، صفت ریخت شناختی جدا شدن یا جدا نشدن محور اصلی سنبله است. در بخش سیتوتاکسونومی بذر ده واحد جمعیتی این گونه جهت مطالعات میتوزی مورد بررسی قرار گرفت و در نهایت دیپلویید بودن آن با 14=n2 و عدد پایه کروموزومی 7 تعیین شد. بعضاً این اعداد با حضور کروموزوم های b تنوع نشان دادند (متن کامل مقاله در قسمت انگلیسی ارایه شده است).

A Cytogenetic Analysis of the Hybrid Secale Cereale L. x Secale Montanum Guss. and Its Progeny.
ITHIN the genus Secale L. hybrids between various perennial forms have all shown regular meiotic chromosome behavior as have hybrids between different annual strains belonging to S. cereale L. In all hybrids between S. cereale and perennial forms, however, a translocation figure has been observed a t metaphase I in the PMC’s. The maximum association is apparently a ring-of-six, but this is seld...
full textTowards a whole-genome sequence for rye (Secale cereale L.).
We report on a whole-genome draft sequence of rye (Secale cereale L.). Rye is a diploid Triticeae species closely related to wheat and barley, and an important crop for food and feed in Central and Eastern Europe. Through whole-genome shotgun sequencing of the 7.9-Gbp genome of the winter rye inbred line Lo7 we obtained a de novo assembly represented by 1.29 million scaffolds covering a total l...

Secale cereale (rye) with its vitally importance can have a marked place in the world cereal production, particularly in North Europe. This study concerns morphology, taxonomy and cytotaxonomy of this species in Iran. Based on the evaluation of 12 qualitative and quantitative morphological characters and using phenetic analysis, it was revealed that, S. cereale occurs in Iran with two subspecie...
full textAn ALMT1 gene cluster controlling aluminum tolerance at the Alt4 locus of rye (Secale cereale L).
Aluminum toxicity is a major problem in agriculture worldwide. Among the cultivated Triticeae, rye (Secale cereale L.) is one of the most Al tolerant and represents an important potential source of Al tolerance for improvement of wheat. The Alt4 Al-tolerance locus of rye contains a cluster of genes homologous to the single-copy Al-activated malate transporter (TaALMT1) Al-tolerance gene of whea...
full textThe Ph1 locus from wheat controls meiotic chromosome pairing in autotetraploid rye (Secale cereale L.).
The Ph1 locus on chromosome 5B enforces strictly bivalent pairing in polyploid wheat, but the exact mechanism of its action remains unknown. Pairing restriction involves not only wheat homoeologues and all alien introgressions but also differentiated homologues. In this study we show that chromosome 5B with its Ph1 locus also controls chromosome pairing in autotetraploid rye by apparently restr...
