About half of all higher plant species are recognizable as evolutionarily recent polyploids, where multiple whole genomes or sets of chromosomes have come together from close ancestors. Additionally, over evolutionary...

Microgravity and chromosome damage
The Karyological Observations of Krikorian and O’Connor look at plant material from flights STS-2 and STS-3 of the Space Shuttle. STS-2, among other things, carried a payload of Helianthus annuus, sunflowers. STS...

Crocus, saffron-omics and the highest value crop
Saffron, the stigma of Crocus sativus, is the highest priced agricultural product (often €/$25 or £15 per gram) and a good example of a profitable crop with sustainability, cultural and social values, and high labour...

Plant molecular cytogenetics in the genomic and postgenomic era
The way that we can address questions in genome evolution and expression has changed enormously in the last five years. We can get huge amounts of DNA sequence for any species for a budget within that of most labs. As...
Chromosome evolution in marginal Aegilops speltoides populations (Review)
Genome restructuring is an ongoing process in natural plant populations and the influence of environmental changes on the genome is crucial.
Faces of Plant Cell Biology: A series on PlantCellBiology.com from Anne Osterrieder
Anne Osterrieder has a new series on her blog called Faces of plant cell biologists, where we are asked a series of questions. So far, it has featured Charlotte Carroll (also an AoBBlog.com guest author here), Chris...
Free—open access paper: Chromosome number variation in two antipodean floras
Italy and New Zealand are very similar in shape, extension, altitudinal and latitudinal range but located in opposite hemispheres. This free—open access paper compares variation in chromosome number in these two...

Repetitive components of Fritillaria genomes
Repetitive components of Fritillaria genomes The genus Fritillaria (Liliaceae) comprises species with some of the largest genomes so far reported. Ambrožová et al. examine the contribution of major repetitive elements...
Translocation breakpoints in SSR-rich chromosomal regions
Translocation breakpoints in SSR-rich chromosomal regions Repetitive DNA sequences are thought to be involved in the formation of chromosomal rearrangements, which are important in polyploid speciation. Molnár et al...
