Diversity and characters in Ethiopian linseed Linum #PAGXXIII Negash Worku
Many people have talked about Orphan crops – those where there has been little genetic or other research – and the characterization, evaluation and exploitation of germplasm at the #PAGXXIII Plant and Animal Genome Conference this week. Today, I am talking about work by Negash Worku on the Diversity and Characters in Ethiopian Linseed Accessions….
Transposable Elements in the Musa and Banana Genome: PAGXXIII conference talk
There has been a lot of talk about transposable elements during the Plant and Animal Genome #PAGXXIII meeting this week. As half or more – often 75% – of all the DNA in a plant or animal genome is typically made of class I retrotransposons and class II DNA transposons, this widespread interest is right!…

Faisal Nouroz : Collaborator from Hazara University, Pakistan on genome organization
Dr Faisal Nouroz completed his PhD at the University of Leicester in 2012, working on mobile element evolution in two contrasting crop groups, Musa and Brassica. Dr. Faisal Nouroz held a Ph.D scholarship from the Higher Education Commission and Hazara University Mansehra, Pakistan and joined the Molecular Cytogenetics Lab, Department of Biology, University of Leicester…
Repetitive DNA in the edible button mushroom
I have a mental picture of the structure of a typical plant genome and typical animal genome, with their transposons (DNA and RNA), tandemly-repeated satellite sequences, minisatellites, microsatellites and other repeats. From this paper, I have a view of repeats in the second most important edible fungus (after yeast, Saccharomyces cerevisiae), the button mushroom Agaricus bisporus. Its genome, with n=13 chromosomes,…
