Origin and evolution of the forage allotetraploid species Stylosanthes scabra
The genus Stylosanthes includes nitrogen-fixing and drought-tolerant species of considerable economic importance for perennial pasture, green manure and land recovery. Stylosanthes scabra is adapted to variable soil...
Variability of interstitial telomeric-like repeats in Mediterranean weedy species
A telomere is the region of DNA that marks the end of a chromosome. The protect the ends of the chromosome, and stop one chromosome from fusing with another. So finding something that looks like a telomere in the middle...
Does this seedling taste fishy to you…? ***
NIgel Chaffey returns with another tale of asyníthchory, this time involving fish.

Allopolyploidy origins and genome structure of barley relatives
Unravelling relationships within Hordeum, one of the largest genera of the tribe Triticeae (Hordeae), is difficult, as many taxa, including most of the polyploids, are of hybrid origin. Mapping phylogenetic...

Flow sorting of C-genome chromosomes from Aegilops
This study uses flow sorting and FISH techniques to further the development of molecular tools to progress introgression breeding in wheat
Combining FISH and chromosome modelling in Typhonium
Sousa et al. combine cytogenetics, using fluorescent in situ hybridization (FISH), and modelling of changing chromosome numbers in a maximum-likelihood framework to study Typhonium, a genus of Araceae with 2n = 24 and...
Evolutionary history of sea barleys (Hordeum marinum)
Hordeum marinum (sea barley) is a complex species that is usually recognized as having two subspecies, marinum (2n = 2x = 14) and gussoneanum (2n = 2x =14 and 2n = 2x = 28). Carmona et al. use comparative physical...
Molecular cytogenetics of repetitive DNA in jute species
The genomes and chromosomes of the important fibre crops white jute and Tossa jute (Corchorus species) are poorly characterized. Information is essential for breeding and improvement, with characters including...
Brassica monosomic alien addition lines
Addition of each chromosome of Brassica oleracea to the chromosome complement of B. rapa results in a series of nine monosomic alien addition lines. Heneen et al. report the development and use of such a series for...
Satellite DNA family in Medicago and allied genera
Satellite DNA is a genomic component present in virtually all eukaryotic organisms and is an important element in genome organization and evolution in plants. Rosato el al. assess the presence and physical distribution...
