So yes, there are alterations to the plants' genotype and phenotype. The plant strains with the phenotypes we choose will certainly survive, as they will be grown, probably in monoculture, for as long as they remain useful. Humans, as a species will benefit too if there are better food crops for feeding the expanding world human population. In modern agriculture, gene transfer is only into 'elite' varieties of plants. Monoculture of these specially selected varieties goes on anyway, and has done so for most of this century.
Gene transfer is just an extension of the sort of breeding programmes that already happen.
Varieties are selected which best suit the environment in which they grow. We will work together with plant breeders to ensure that our original transgenic plants are crossed with the best Australian cultivars. There is often discussion or debate about issues associated with biotechnology. The whole subject of development of new varieties of plants raises issues of ownership of the new varieties. Genes and transgenic organisms are able to be patented in Australia and transgenic plants are protected by plant variety rights.
