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,…

Saffron crocus, cooking and Iran on the radio

The spice Saffron is valued worldwide for its flavor, aroma and color. I’ve just broadcast an interview with Robin Young produced by Jill Ryan for NPR’s Here and Now program which let me tell you something about my enjoyment of saffron both as a consumer and scientist. Saffron is unusual in that it is equally…

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….

Needs for understanding water and food security

“The earth’s land surface receives about 110,000 km3 of rainfall annually. More than half of this water is evapotranspired (transmitted from soils and through plants to the air); about 20,000 km3 falls on land that is cultivated in some form; and about 40,000 km3 becomes available in dams, lakes, rivers, streams and aquifers for human…
