New Insight on Cereal's Vernalization

August 28, 2013

A new research finding by European scientists revealed that flowering plants came into being when duplications took place in the genome of their ancestors. The researchers found large numbers of DNA duplications in the very parts of the genome that are unique to flowering plants. Furthermore, the study provides insight on cereal's vernalization, a process wherein plant acquires the ability to flower in the spring after its long exposure to  winter.

The vernalization gene – the so-called FLC gene, seen in other plants requiring a cold period in order to be able to flower – has not previously been found in winter cereals. However, now that the researchers knew exactly where they had to look, they were able to find genes related to FLC genes. This gave new direction to the study of vernalization in cereals.
