New tomato varieties developed in Belgium

According to the earth and Life Institute of Catholic University of Leuven, Belgium, a team led by researcher giannium developed a new tomato variety through gene transformation, which can not only grow in dry land, saline alkali land and other poor soil conditions, but also yield 30% higher than the common variety, and the fruit meets the requirements of food safety Jaynem said that the tomato has these advantages because the researchers only modified the genes of the root cells of the plant, and the whole plant's chromosomes did not change Therefore, the fruits of tomato are not affected, and the whole plant will not synthesize substances harmful to the natural environment When the team studied the plant's roots sending auxin messages to its stems and leaves, it locked in a gene called cytokinin, a substance that slows down plant death, Ghanem said When plants are short of water or facing unfavorable soil conditions, there will be a phenomenon of conditioned reflection - the root cells of plants will send information materials to the stems and leaves, and start self-protection mechanisms, such as reducing water consumption, resulting in reduced nutrient delivery, affecting fruit yield On the contrary, if the plant root has enough cytokinin, it can be more active in dealing with bad soil conditions, send more "positive and optimistic" information materials to the stem and leaf, and improve the adaptability of the plant.
