As soon as spring blooms, the scientists have found through research that the signalling principle of the arrival of plants in spring after the winter. According to an article published in the latest issue of Science magazine, a protein in plants can respond to light, triggering a series of actions and opening the door to flowers. Previous studies have reported that a protein called CONSTANS is responsible for managing the flowering process of plants. It is very sensitive to the length of the day. In this latest study, Steve Keyi of the American Scripps Research Institute discovered the second protein, FKF1, which can control the activity of CONSTANS while grasping the flowering time of plants. Through animal hybridization experiments, the researchers found that FKF1 can interact with a transcription factor (CDF1) and use this process to inhibit CONSTANS. Since FDF1 can reduce the number of CDF1, mutant plants lacking the FKF1 gene will have higher CDF1. In addition, their flowering time is later than that of normal plants, and CONSTANS activities are relatively few. According to the research report, in the wild plants, with the advent of spring, daylight hours will be extended during the day, and the light-sensitive FKF1 will destroy more CDF1 in the afternoon, thus limiting CONSTANS in the critical period of flowering, but the scientists The principle of this process is still poorly understood.
