SYSTEMATIC STUDY OF SECALE CEREALE IN IRAN
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...
متن کاملA 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...
متن کاملTowards 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...
متن کاملIsoprenoid Biosynthesis and Stability in Developing Green and Achlorophyllous Leaves of Rye (Secale cereale L.)
Formation o f major prenylquinones and carotenoids was investigated by comparing the incorporation o f [14C]mevalonate into segments o f different age from green and etiolated leaves o f 22 °C-grown rye seedlings (Secale cereale L.) and from 32 °C-grown rye leaves which contained bleached and proplastid-like ribosome-deficient plastids, due to a heat-sensitivity o f 70S ribosome formation. The ...
متن کاملUltrastructural analysis of chromatin in meiosis I + II of rye (Secale cereale L.).
Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers. It could be shown for the first time that organization of basic structural elements (coiled and parallel fibers, chromomeres) changes dramatically during the progression to metaphase I and II. Controlled...
