W-12 is a virus that seriously harms the growth of grains and causes a large reduction in grain production every year. Scientists have found that inserting a gene extracted from W-12 into a grain gene that is susceptible to infection can make The grain produces antibodies to W-12, which greatly reduces losses.
When plants acquire antibodies against certain viruses through genetic mutations, they will increase their resistance to certain other viruses does not strengthen the above conclusion if the following items are true.
