Final answer:
A farmer can use DNA technology to combat the canna virus by transferring disease-resistant genes into crops, creating genetically modified organisms (GMOs) that withstand the virus better. Genomics help generate new hybrid strains and improve disease resistance in agriculture. This biotechnology enhances crop production and sustainability, leading to more efficient farming practices.
Step-by-step explanation:
Using DNA technology, a farmer dealing with canna virus could potentially save their crops by incorporating genetic resistance into the plants. Modern agricultural biotechnology enables the development of crops with specific genes that confer resistance to various stresses such as pests, diseases, drought, and saline soils. By identifying the genes responsible for disease resistance from other plants, scientists can transfer those genes into the affected crops, making them capable of withstanding the canna virus.
For example, genomics in agriculture allows for the improvement of disease resistance by generating new hybrid strains. Genomic data can also be utilized to produce GMOs (genetically modified organisms) that exhibit enhanced resistance against plant diseases. This not only helps in managing the current problem but also aids in future-proofing the crops against similar threats.
Additionally, crops engineered to tolerate specific herbicides can make weed control more efficient and cost-effective, contributing to cheaper and more manageable production. Thus, these biotechnological advancements can increase crop yields, quality, and sustainability in agriculture.
