Introduction: scientists in the United States have isolated a gene that controls the growth of seedlings from a mustard plant for laboratory research This gene can speed up the plant to jump over the vulnerable young stage The achievement was made by bellardini, a botanist at the University of Pennsylvania, and his colleagues In their experiment, they controlled the gene "squint" in the seedlings, and found that the seedlings grew rapidly into adult plants The researchers judge according to the characteristics of different shapes and types of leaves in different life stages of plants When the "squint" gene in the seedlings is inhibited, the leaves of mature plants will grow as soon as the seedlings grow, which means that the plants skip the young stage and directly enter the adult stage But the time of flowering and fruiting was not affected by gene change, and the changed gene was passed on to the next generation through seeds Eb2 scientists have confirmed that the "squint" gene exists in corn and rice, and may exist in all flowering plants The discovery could help to develop new types of corn and other crops that can jump over vulnerable growth stages Eb2
