Humans rely on crop plants for food, medicine, clothing and many other functions. The Hagenblad lab studies how crop plants have spread across the world and how they have adapted to different climates and cultivation methods.

In this article, the researchers conducted a genetic analysis of archaeological barley grains from Gran Canaria, examining the changes in a single cultivated population over 1400 years.

Thousand-year-old seeds, and traces hidden in the soil for more than 5,000 years, provide clues to how people and their crops were affected by climate change. This knowledge may help us adapt to changes in our lifetime and in the future.

Have you tried the national dish gofio while on holiday on the Canary Islands? If so, you have eaten the same food as the original inhabitants ate, nearly 2,000 years ago.

The 200-year-old malting barley variety 'Chevalier' was for a long time world-leading in beer brewing and is thought to have originated from a single plant. Researchers have investigated this claim in a new study.

Differences in long-distance trade can have significant effects on genetic diversity in agriculture. A study of 120-year-old seed samples from Jämtland shows that unique local varieties can develop when seed exchange instead takes place locally.

Is it possible that a single individual influenced which crops were cultivated over large areas of Fennoscandia? In a new study, clues from DNA from old barley indicate that the priest Lars-Levi Laestadius may have played an important role.

Have you ever eaten a potato onion? It’s highly likely, but you probably called it a ‘shallot’. Now researchers have studied this lesser known relative of the common bulb onion, and we may be seeing a renaissance of this venerable vegetable among...
