A reassessment of the genome size – invasiveness relationship in reed canary...
What is it that can make a plant invasive? There’s no clear answer because a combination of factors can help. Also, different traits may play a role at different stages of an invasion. Pulling apart...

Retrotransposons in holocentric chromosomes of Eleocharis with different...
Long terminal repeat-retrotransposons (LTR-RTs) comprise a large portion of plant genomes, with massive repeat blocks distributed across the chromosomes. Eleocharis (Cyperaceae) species have...

Establishing the cell biology of apomixis in Boechera
The genus Boechera (Brassicaceae) is comprised of both sexual and apomictic species, permitting comparative analyses of meiotic disturbances and parthenogenesis. Hybridization, polyploidy and...

Sexuality and apomixis in Hieracium are tightly associated with ploidy
Asexual reproduction via seeds (apomixis) is an important speciation mechanism in angiosperms, but its frequency is largely unknown. Mráz and Zdvořák used flow cytometric seed screening to unravel...

Cytogeography of Cystopetris fragilis complex
The widely distributed Cystopteris fragilis brittle bladder-fern, complex is a challenging system for studying polyploid evolution, cytotype diversity, distribution and ecology. Hanušová et al. screen...

Puzzles in Moss Genome Evolution
Some plants have pairs of chromosomes, they’re diploid organisms like us. Other plants have more than two copies of chromosomes, they’re polyploid. Strawberries can even be octoploid. Mosses can be...

A long-lasting connection? Links between genome size and stomata size in plants
The variation in genome size between different plant species is enormous, with a variation of 2300-fold in flowering plants alone. Whilst variation in plant genome size is well recorded, it is...

Move over Factor 50! Can increasing their number of chromosomes help protect...
UV-B radiation is not just dangerous to us, but is also a threat to plants growing in a variety of environments through its damaging effects on photosynthetic machinery and DNA. Whilst we can escape...

More DNA in golden-brown algae leads to bigger cells, but slower growth
Eukaryotes, like animals, fungi, plants, and you, carry nuclear DNA in within the nucleus of the cell. The amount of nuclear DNA varies from organism to organism, and some cells have to physically...
