Biochemists have announced that they have mastered technology to effectively control Arabidopsis enzymes in plants. Using this technology, humans can change the smell of vegetables and fruits. Arabidopsis is a combination of two substances, including two Diene oxide and catalase, which can produce jasmine and green leaf volatiles GLV, the latter determines the aroma characteristics of vegetables and fruits. From this we can infer:. ['Jasmine contains more Arabidopsis enzymes than other flowers.', 'Humans cannot change the smell of plants before mastering this technology.', 'Vegetables and fruits will change smell if Arabidopsis enzymes are removed.', 'Diene oxide and catalase determine the smell of vegetables and fruits.']
