Domestication, polyploidy and genomics of crops and weeds PAGXXV
Plant and Animal Genome Conference in San Diego #PAGXXV each January is the chance to join 3500 people working in genomics. I presented a talk on the molecular cytogenetics group’s work, starting with consideration of early stages of crop domestication, and then thinking about how we can make agriculture more sustainable. I also considered weeds,…

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….
Molecular cytogenetics research group October 2014
At our lab. meeting a couple of weeks ago, we were happy to welcome two new PhD students to the group. Here we all are in the lobby of our Adrian Building. We are from six countries, and work on a diverse range of molecular cytogenetics projects. From left to right, left of DNA molecule:…

Worku Mhiret: Biodiversity and its exploitation in Ethiopian Linseed
Worku Mhiret from the University of Gondar, Ethiopia and Pat Heslop-Harrison (University of Leicester, UK) are working on linseed or flax: measuring the diversity of accessions from Ethiopia and comparing this with varieties from Ireland, Canada and elsewhere. We are also making crosses between lines and between cultivars and wild species of Linum; these are…
Nouf Alsayied: PhD student with Saffron Crocus at the University of Leicester and faculty member Umm Al-Qura University, Kingdom of Saudi Arabia
My research focuses on understanding the origin and diversity of the genus Crocus (Iridaceae), with particular emphasis on a triploid sterile plant, Crocus sativus (2n=3x=24) that yields Saffron, one of the most expensive spices on earth. The saffron is the stigmas of the flowers, and nearly 200,000 must be collected to give 1kg of spice,…
The origin of saffron: Crocus sativus
Our research projects are studying the origins and diversity in several polyploid crops: banana, wheats, Brassica, Panicum millets, Nicotiana and the saffron crocus, Crocus sativus. The spice saffron is the stigmas of the flowers, and widely appreciated in Indian and Mediterranean cooking. Saffron crocus is a sterile triploid, with 2n=3x=24 chromosomes – that is, 3…
