A team of researchers at the University of California, Davis, has isolated and cloned the second of two genes that control vernalization _ the plant's ability to flower only after exposure to a cold winter.

This discovery also opened the door to manipulation of the process of vernalization, which could generate new, commercially significant varieties of wheat with shorter growing periods, earlier flowering or no flowering at all, said Dubcovsky.

Sonora in Mexico ), spring wheat ( not requiring a period of vernalization ) is also sown in the autumn ( November / December ) and harvested in late spring ( April-May ) the next year.

Later however, Lysenko inaccurately asserted that the vernalized state could be inherited, i . e . the offspring of a vernalized plant would behave as if they themselves had also been vernalized and would not require vernalization in order to flower quickly.

In 1927, at 29 years of age, working at an agricultural experiment station in Azerbaijan, he embarked on the research that would lead to his 1928 paper on vernalization, which drew wide attention because of its potential practical implications for Soviet agriculture.

The same group of researchers who last year cloned the first wheat vernalization gene _ VRN1, the gene that sets off the plant's flowering _ this year identified VRN2, the gene that tells the plant to wait through weeks of cold weather before flowering.

This is why Lysenko claimed vernalization would give greater productivity than it did; he believed the ability of his vernalized seeds to flower faster and produce more wheat would be passed on to the next generation of wheat seeds, thus causing vernalization to further amplify the process.

Domesticated chickpea is considered vernalization insensitive ( it can flower at all times of the year ), whereas wild " Cicer reticulatum " shows a considerable flowering advance ( of up to 30 days ) in response to vernalization which means that the plant would have to grow in areas where it is exposed to a prolonged period of cold before it can properly grow.
