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...
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 کاملHybrids and amphiploids of Aegilops ovata L. with Secale cereale L.: production, morphology and fertility.
Hybrids (2n = 3x = 21) between Aegilops ovata and Secale cereale were produced via embryo rescue. Most hybrid morphological traits were intremediate between parents, the plants grew vigorously but were completely sterile. The average frequency of chromosome associations at metaphase I was 19.57-20.19 univalents and 0.40-0.86 rod bivalents. The fertility of the hybrids was restored by doubling t...
متن کاملCyanidin 3-Gentiobioside from Primary Leaves of Rye (Secale cereale L.)
Primary leaves of rye (Secale cereale L. cv. Kustro) show a heterogeneous, tissue-specific pattern of flavonoids being composed of the two C-glycosylflavone glycosides isovitexin 2"-0-arabinoside and isovitexin 2"-0-galactoside (located in the epidermal layers) [1, 2], the two flavone glycosides luteolin 7O-diglucuronide and luteolin 7-O-diglucuronide 4'O-glucuronide [3] and the two anthocyanin...
متن کاملThe 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...
