摘要:The paper reports on the study of DNA methylation patterns in chromosomes of an octoploid selection obtained from an amphiploid Avena barbata × Avena sativa ssp. nuda , their alteration and plant structural changes induced by 5-azacytidine (5-azaC) treatment. Subtelomere/tel...

摘要:Abstract(#br) Key message(#br)The development of oat endosperm is modified by chromatin and nuclei elimination, intrusive growth of cell walls, and polyploidisation of cell clones. The last event is correlated with somatic crossing-over.(#br) Abstract(#br)Grass endosperm is ...

摘要:Abstract(#br)The basis of any patterns of variation in plant populations is the breeding system they express. In the genus Brachypodium , the breeding system ranges from autogamy in facultatively chasmogamic Brachypodium distachyon to allogamy in obligatory chasmogamic B. pinnatu...

摘要:Abstract(#br)Morphology of ripe lodicules in wheat taxonomic species was analyzed for all ploidy levels. From the initial set of sixteen characters, the best representatives and discriminants were selected. Length of main lobe and hairiness of this lobe as well as cushion appeare...

摘要:Abstract(#br)In situ hybridization of total genomic DNA was used to analyse lines derived from an amphiploid between tetraploid wheat, Triticum durum Desf. (2 n =4 x =28), and the wheatgrasses Thinopyrum distichum (Thunb.) A. Löve (2 n =4 x =28) and Lophopyrum elongatum (Hos...

摘要:A series of Hordeum vulgare cultivars was irradiated by X-rays to induce mutations in endosperm. Many structural defects of endosperm were revealed in plants irradiated 8 DAF. Change of a cell cycle was especially frequent and this was visible in the form of clones of small or la...

摘要:A group of closely related species from the section Bromus: B. secalinus, B. commutatus and B. racemosus were described by characteristics of the abaxial epidermis of lemma. B. commutatus appeared as the most extreme unit against other types. B. secalinus exhibited an intermediat...

摘要:Several examples of natural mutants in the grass family were presented. All appeared as changes in inflorescence structure. In mutated plants chasmogamy was restricted due to anomalous lodicules or compactness of ears. A rare glumeless mutation in Agropyron pectiniforme reduced t...

摘要:Patterns of reproduction were studied in a series of inter- and intraspecific units in the genus Avena. The range of variation of the mating system is from autogamy to allogamy. The first system is expressed in cultivated types, while the second is observed in wild and weedy ones...

摘要:Composite starch granules, the main product of assimilation in oat endosperm, were analyzed in the accessions of both wild and cultivated diploid species of the genus Avena. Simple starch granules are mostly synthesized in the outer parts of the endosperm tissue. The size of...
