High‐quality genomes of four wild raspberry species, analysis of their genetic relationships, identification of centromeres as markers for tracing their hybrid origins, exploration of fruit quality regulation, and discovery of a gene blocking anthocyanin transport and thus causing yellow fruits provides valuable resources for raspberry breeding ...

Cytological, Phenological and Molecular Characterization of B (S)-Genome Synthetic Hexaploids (2n = 6x = 42; AABBSS) [PDF]
The B(S) genome diploids (2n = 2x = 14) are a unique reservoir of genetic diversity that can provide wheat breeders a rich source of allelic variation for stress traits that limit productivity. Restricted in practical use essentially due to their complex

Interactions between wheat, rye and Aegilops ventricosa chromosomes on homologous and homoeologous pairing [PDF]
Different wheat-rye, Ae. ventricosa-rye and wheat-ventricosa-rye genome combinations were analysed at meiosis. In all cases it was possible to estimate the frequencies of the different types of homologous and homoeologous pairing, by using a C-banding technique. Rye homologous pairing decreased in the presence of wheat and Ae.

VERNALIZATION2 alters early tiller development in a facultative spring hexaploid bread wheat
Summary An extended period of cold exposure enables the process of vernalization in winter cereals and is important for the synchronised timing of the floral transition. The cereal‐specific floral repressor VERNALIZATION2 (VRN2) has an integral role in vernalization, yet this locus remains poorly characterised in facultative spring hexaploid wheat ...

ABSTRACT Floret fertility is a key determinant of grain number per spike and an important factor in cereal crop yield. However, the mechanisms by which phytohormone signalling and transcription factors coordinately regulate floret fertility and spikelet development are not well understood, especially in wheat.

Postglacial colonization and parallel evolution of metal tolerance in the polyploid Cerastium alpinum [PDF]
The Fennoscandian flora is characterized by a high frequency of polyploids, probably because they were more successful than diploid plants in colonizing after the last Ice Age.

Chromosome instability in intergeneric hybrids of Triticum aestivum;× tritordeum (amphiploid Hordeum chilense×Triticum turgidum) with high dosage of Ph1 gene of wheat [PDF]
In somatic cells of intergencric hybrids Truicum uestirum (mono-isosomic 5BL, 2n=6x=4f)x trinordum 12n = 6x = 42, amphiploid Hordeum clulense x Triticum turgidnm)it was observed that high dosage of the long arm of 5B induced chromosome instability in ...

ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.

Mysterious meiotic behavior of autopolyploid and allopolyploid maize
This study was aimed to investigate the stability of chromosomes during meiosis in autopolyploid and allopolyploid maize, as well as to determine an association of chromosomes between maize (Zea mays ssp. mays Linnaeus, 1753) and Z.
