... Molecular Biology Revolutionized the Study of Plants In the second half of the 20th century the discovery of the structure of DNA and RNA, the steps in protein synthesis, and other great discoveries of molecular biology revolutionized the study of plants at all levels, from cells to ecosystems. Taxonomists, evolutionists, ecologists, physiologists, and developmental biologists are now using molecular techniques and are discovering many responses and mechanisms that were not accessible This paper was presentecl at the National Acaclemy of Sciences colloquium, "The Future of Evolution," held March 1 6-20, 2000, attheArnoicl and Mabel Beckman Center in Irvine, CA.

... It is now possible to identify, with much precision, the particular genes responsible for traits. And, with the techniques of molecular biology, scientists can introduce or eliminate genes for specific traits.
