Chromosomal distribution of pTa-535, pTa-86, pTa-713, 35S rDNA repetitive sequences in interspecific hexaploid hybrids of common wheat (Triticum aestivum L.) and spelt (Triticum spelta L.)
Fluorescent in situ hybridization (FISH) relies on fluorescent-labeled probes to detect specific DNA sequences in the genome, and it is widely used in cytogenetic analyses. The aim of this study was to determine the karyotype of T. aestivum and T. spelta hybrids and their parental components (three common wheat cultivars and five spelt breeding lines), to identify chromosomal aberrations in the...
متن کاملCytological characteristics of F2 hybrids between Triticum aestivum L. and T. durum Desf. with reference to wheat breeding.
Cytological and agronomic characteristics of a F2 population from Triticum aestivum L. x T. durum Desf. hybrids were analyzed plant by plant. Means of morphologic traits in the F2 population were similar to those of the low-value parent. On average, F2 hybrids had 36.54 chromosomes per plant, indicating that each gamete lost 2.73 chromosomes at meiosis of the F1 generation. More than half of pl...
متن کاملIsolation Analysis Of Flavonoids From Triticum Aestivum
Flavonoids tricin, iso-orientin, vanillin, iso-vitexin, apigenin, 8-hydroxy flavones, 4’-hydroxy chalcone have been isolated from leaves of early stage triticum aestivum. Their quantitative analysis has been done through elemental and spectral analysis.
متن کاملThe wheat (Triticum aestivum L.) leaf proteome.
The wheat leaf proteome was mapped and partially characterized to function as a comparative template for future wheat research. In total, 404 proteins were visualized, and 277 of these were selected for analysis based on reproducibility and relative quantity. Using a combination of protein and expressed sequence tag database searching, 142 proteins were putatively identified with an identificat...
متن کاملProduction of embryo - callus - regenerated hybrids between Triticum aestivum and Agropyron cristatum possessing one B chromosome
mdash; Plant regeneration from immature intergeneric embryos through direct callus induction was investigated in the case of hybridization between T aestivum cv Chinese Spring (2n = 6x = 42, AABBDD) and A cristatum 4x with one B chromosome (2n = 4x = 28 + 1 B, PPPP). Twenty-three abnormal immature hybrid embryos were directly cultured on MS solid medium with 2 mg / L 2,4-D to induce calli which...
