Plants bind solar energy to organic matter via photosynthesis and assimilation of carbon dioxide from the atmosphere and comprise the major source of nutrition and bioenergy. Plant biotechnology contributes to solution of important constraints in food and feed production and creates new technologies and applications for the sustainable use of plant resources. Genome-wide approaches such as massive parallel sequencing and microarrays to study gene expression, molecular markers for selection of important traits in breeding, characterization of genetic diversity with the aforementioned approaches, and somatic hybridization and genetic trans form at ion are important tools in plant biotechnology. In this paper, studies carried out on enhanced resistance to viruses and tolerance of cold stress in potato, genetic modification of flower pigmentation and morphology in gerbera, production of edible vaccines in transgenic barley seeds, and expression of heterologous proteins for pharmaceutical purposes from vector viruses were chosen to exemplify the general utility of biotechnological approaches and also how plant biotechnology research has developed on cultivated plants at University of Helsinki. The studies reveal cellular and genetic mechanisms and provide scientific information that can be used for widening the uses of crop plants. They can also be used to detect any putative risks associated with the use of the biotechnological application in agriculture and horticulture and to develop practises which reduce any inadvertent negative consequences that plant production may have to the environment.
