Just like animals, plants can develop some diseases, such as the mosaic virus, verticillium wilt, etc. Some varieties of a plant are naturally resistant to those diseases. This is a valued trait, and plants may be bred that retain that characteristic. This prevents losing an entire crop when a plant disease sweeps through a field. Remember the famine in Ireland was caused by a plant disease that killed most of the potato crop in Ireland.

Why genetically modified crops are made?
Genetically modified crops are made in order to make a desired trait, such as high yield, disease resistance, large fruit etc. more pronounced and/or undesired traits, such as toxins and large seeds in fruit etc. less pronounced. For example, some crops may have a resistance to a certain disease that other crops do not have, the gene that causes the resistance to the disease can be introduced to another type of crop in order to create resistance in the other type of crop. Also some crops may have undesirable traits such as naturally occurring toxins which are a defence mechanism of the plant. Genetic modification can be used to stop the expression of the genes which cause these toxins to be produced, making crops safer for consumption.
Why have we developed gm crops?
To increase their resistance to disease and predation. To improve the yield. To allow crops to grow more quickly and in more adverse conditions. To reduce starvation in the world.

What invention did antonio carlos laurena?
Dr. Antonio Carlos Laurena was a Filipino scientist. He contributed largely to the study of agricultural crops and their biomechanical uses, and invented a method on how to improve the post-harvest disease resistance of crops.

Why do you think fungal diseases can spread so quickly among crops or other plants?
When a population of wheat, humans, or other living things is first exposed to a disease, the disease generally infects or kills a substantial portion of the population. Genetic resistance is resistance to a disease that arises after prior generations have survived it. The fungi spreads through the soil, water supply, air, infected tools and animals.
The resistance of an organism to disease is known as?
The resistance of an organism to disease is known as immunity. This defense mechanism helps protect the body from harmful pathogens such as bacteria, viruses, and parasites.
Are farm crops getting more resistant to insects disease and other pests?
Yes and no. More resistance is being both bred and engineered into crops all the time. However, the germplasm pool for the major crop classes such as corn, soybeans and wheat is shrinking all the time which leaves the worldwide supplies at more risk should a disease or insect adapt to existing varieties. This is why plant breeders are frequently trying to find new "landraces" (old original plant forms) of crops to breed into existing germplasm to create more varied resistance.
What are two characteristics biologists look for in crops?
Not 100% sure on this, but I would say productivity (the varieties ability to produce much fruit) and resistance (the plants ability to withstand drought, temperature changes, and disease).
