When the plant senses the light, it gets rid of extra energy and creates more leaves. When the plant is in shade, the protective system is turned off, but the process is slow. s genes, the scientists were able to increase the amount of leaf growth on plants between 14 and 20 percent. s genes in order to make it use sunlight more quickly.
