Plant culture laboratory. Female technician examining a tissue culture of a strawberry plant, Fragaria sp., in a plant culture laboratory. The cultures are grown under carefully controlled conditions for research on nutrition, pest resistance, gene mapping and genetic engineering. Gene mapping allows more efficient breeding of strawberry plants for desirable qualities. Similarly genetic engineering can produce new varieties with improved yield and resistance to pests and pollution.
