TLDR
Studies of meiosis in diploid hybrids showed that the frequency of pairing between H. vulgare and H. bulbosum chromosomes varied between different cross combinations, although 21-chromosome cells were at the highest frequency.Abstract:
Diploid and triploid interspecific hybrids were produced from crosses between four Hordeum vulgare varieties and two diploid and two tetraploid Hordeum bulbosum genotypes. These were studied cytolo...read more

The barley Genome and its Relationship with the Wheat Genomes. A Survey with an Internationally Agreed Recommendation for Barley Chromosome Nomenclature
TL;DR: The information collected demonstrates largely similar genetic contents and collinearity of gene loci in the seven chromosomes of barley and in those of other members of the Triticeae, indicating that the whole group can be considered as a single gene pool.

Unlocking the secondary gene-pool of barley with next-generation sequencing.
Neele Wendler,Martin Mascher,Christiane Nöh,Axel Himmelbach,Uwe Scholz,Brigitte Ruge-Wehling,Nils Stein +6 more
TL;DR: Next-generation sequencing based strategies for unlocking genetic diversity of three diploid introgression lines of cultivated barley containing chromosomal segments of its close relative H. bulbosum provided fast and reliable detection and mapping of the introgressed segments and enabled the identification of recombinant plants.

Transfer of a dominant gene for powdery mildew resistance and DNA from Hordeum bulbosum into cultivated barley (H. vulgare)
J. Xu,K. J. Kasha +1 more
TL;DR: This is the first conclusive report of the stable transfer of disease resistance and DNA from H. bulbosum to H. vulgare and the progenies produced could serve as an important resistant source in plant breeding.
Journal ArticleDOI
Genome relationships in the perennial Triticeae based on diploid hybrids and beyond
TL;DR: Diploid intergeneric hybrids were synthesized among diploid species of the genera Agropyron Gaertn and Pseudoroegneria, finding that Jb and Je (= E) are the most closely-related genomes, with the genetic similarity ranging from 0.50 to 0.68.

Pattern of enzyme hydrolysis in raw sago starch: effects of processing history
Wei Wang,A.D. Powell,C.G. Oates +2 more
TL;DR: In this article, the authors used Novo Nordisk and Sigma α-amylases and glucoamylase to study the surface erosion, pitting and crevassing of sago starch.

The heterochromatin distribution and genome evolution in diploid species of elymus and agropyron
T. Ryu Endo,Bikram S. Gill +1 more
TL;DR: The acetocarmine–Giemsa C-banding technique was used to study heterochromatin distribution in somatic chromosomes of diploid Elymus junceus (= Psathyrostachys juncea).
Journal ArticleDOI
Chromosome banding patterns in cultivated and wild barleys ( Hordeum SPP).
TL;DR: An investigation of seven species of wild barley and ten different forms of the cultivated species (H. vulgare) has revealed that all the species and cultivars have mostly procentric constitutive heterochromatin.
Journal Article
Chromosome order--possible implications for development.
TL;DR: Chromosomes are arranged in ordered haploid sets around the centre of the metaphase plate at mitosis in several grass species and hybrids, and order may constrain karyotype and hence species evolution.
