Genes and territories.
Abstract
This brief article describes how genes have been redistributed from local landraces and ecotypes via selection to cultivars grown on a large scale. The advent of molecular biology has accelerated this process by improved selection and via genetic engineering will permit the spread of novel genes or genes foreign to the original plant. Biotechnology may also aid the breeding of varieties specifically adapted to a particular location if the size of the market is sufficiently large. In this way, genesallowing plants to grow more successfully in the abiotic and biotic conditions of a particular area may therefore become localized again.
