Plants can also send messages. how can they be transmitted? Experiments have proved that polypeptides can transmit plant defense messages.
Plants can also send messages! Chen Yong'an, a student at Taichung No. 1 Middle School, explored how the model organism "Arabidopsis thaliana" conveys defense messages through "salt stress", proving that the "winning peptide" between amino acids and proteins can be used as plant signal transmission, and found that it is helpful to the development of farming technology. he won the silver medal in the 10th Tunisia International Engineering and Technology Festival with the study of the root transmission of defense messages between Arabian mustard individuals.
Chen Yong'an said that biological defense mechanisms are very important for the survival of ethnic groups, and plant defense mechanisms are less explored than animals. Because plants are unable to move freely and avoid environmental pressures such as diseases and insect pests and salinity, they develop more complex defense mechanisms than animals and take Arabian mustard as the object of study under the advice of the instructor.
Chen Yong'an said that during the experiment, after creating a "salt stress" with a high salinity solution, a small number of Arabian mustard secreted winning peptides, which were received by other plants that did not suffer from salt stress, and there were signs of salt stress in other plants. this also confirms that when a small number of plants suffer from stress, they can use polypeptides to warn the surrounding unaffected plants to defend in advance.
Chen Yong'an said that although his research is to confirm the role of peptides through salt stress, diseases and insect pests are also the direction of future research. He pointed out that environmental stress is an important factor affecting crop yield, and a better understanding of the mode of action of peptides in the future will help to develop emerging pest control technologies.
