Crop Biotechnology: Genetic Modification And Genome EditingPlant molecular biology came to the fore in the early 1980s and there has been tremendous growth in the subject since then. The study of plant genes and genomes, coupled with the development of techniques for the incorporation of novel or modified genes into plants, eventually led to the commercialisation of genetically modified (GM) crops in the mid 1990s. This was seen as the start of a biotechnological revolution in plant breeding. However, plant
