Plant biotechnology. Conceptual image of plant biotechnology or genetic engineering, showing a spurge seedling (Euphorbia characias wulfenii) with a petri dish. The aim of genetic engineering is to alter the plant's DNA (deoxyribonucleic acid) and thus change the plant's genetic code. This will alter the characteristics of the plant, possibly conferring protection against parasites and diseases, as well as increasing yield.
