How do you know the plants that should bloom in the early spring?
The mechanism responsible for the flowers emerge in spring is known as vernalization, and occurring at the exact time is essential for pollination to occur. According to a recent study by scientists at the University of Texas (USA), plants recognize this station because”remember” who have just undergone a long cold period thanks to along RNA molecule called COLDAIR.
According to the authors of the research, this molecule creates a memory cell to plants when you go from 30 to 40 days of cold. At that time, a gene called FLC, which has been engaged insuppressing the production of flowers in the fall and winter, is silenced, and the plant is preparing to bloom.
