Human uses of plants or dried flowers. Ornamental plants have sometimes changed the course of history, as in tulipomania. Basic biological research has often been done with plants. In genetics, the breeding of pea plants allowed Gregor Mendel to derive the basic laws governing inheritance, and examination of chromosomes in maize allowed Barbara McClintock to demonstrate their connection to inherited traits. The plant "Arabidopsis thaliana" is used in laboratories as a model organism to understand how genes control the growth and development of plant structures. NASA predicts that space stations or space colonies will one day rely on plants for life support. Scientific advances
Journal of Heredity Journal of Heredity The Journal of Heredity is a peer-reviewed scientific journal concerned with heredity in a biological sense, covering all aspects of genetics. It is published by Oxford University Press on behalf of the American Genetic Association. The trends in topics that have been published in the journal reflect the history of the discipline of genetics. Early issues included many papers on eugenics, particularly under the editorial leadership of the journal's first two editors-in-chief, Paul Popenoe and R. C. Cook. Emphasis on eugenics in the journal declined throughout the 1940s and 1950s as support for the topic waned in
