Characteristic of a transgenic crop: They contain a gene that was transferred into their DNA from a different species or organism.

Plant diseases usually occur when: The pathogen, susceptible host plant, and environmental conditions ideal for the pathogen are all present. Transgenic crops are characterized by the presence of a gene that has been transferred from a different species or organism into their DNA. This genetic modification is achieved through techniques such as genetic engineering. By introducing specific genes, scientists can confer desirable traits to crops, such as resistance to pests, diseases, or tolerance to environmental conditions. Plant diseases typically occur when all the necessary conditions are present. These conditions include the presence of a pathogen capable of causing the disease, the presence of a susceptible host plant that can be infected.
