“…The discovery of the plant hormone indole-3-acetic acid, the development of improved nutrient solutions, informed choice of plant material, and appreciation of the importance of aseptic cultures led to sustained growth of callus tissues of carrot and hybrid tobacco. This significant milestone was achieved by Roger Gautheret (1939) and Pierre Nobécourt (1939) in France and Philip White (1939a) in the USA within weeks of each other. Nevertheless, with the onset of World War II, they remained unaware of each others' work for many years.…”

The groundbreaking research carried out by Philip R. White in the 1930s and 1940s played a critical early role in the development of modern plant biotechnology and the production of biotech crops. He gained instant fame and became a historical figure early in his career by becoming the first person to attain unlimited growth of cultured plant tissues. White was one of the best known and most influential figures of his generation in plant cell culture research. His tireless and lifelong efforts to promote the use of plant cell culture systems inspired a generation of scientists and stimulated much scientific activity. White was not only a brilliant and visionary scientist but also a highly principled man who spoke courageously about the great moral and political issues of his day. He was admired as much for his science as for his humanity. His belief that plant cell culture research was not well represented at national and international meetings, and his deeply held conviction that science had to be international and without borders in order to be of service to humankind led to the founding of the International Association for Plant Biotechnology in 1963, currently the largest forum for the international plant biotechnology community. This tribute honors and celebrates Philip R. White for his inspiring science, for his kind and generous mentoring of young scientists, for his advocacy of plant cell culture research and its applications, for his promotion of international scientific exchange and cooperation, and for his leadership in the founding of the International Association for Plant Biotechnology.

“…The development of improved nutrient solutions, informed choice of plant material, and appreciation of the importance of aseptic cultures, led to long-term or indefinite cultures of excised tomato roots, and cambial tissues of tobacco and carrot, by White (1934White ( , 1939 in the United States, andGautheret (1934, 1939) and Nobécourt (1939) in France. The discovery of the naturally occurring auxin indole-3-aetic acid (IAA) and its beneficial effects on plant growth (Went 1928;Kögl et al 1934;Thimann 1935), soon led to its incorporation in plant nutrient media (see White 1943;Gautheret 1985).…”

The foundations of modern plant biotechnology can be traced back to the Cell Theory of Schleiden (Arch Anat Physiol Wiss Med (J Müller) 1838:137-176, 1838) and Schwann (Mikroscopische Untersuchungen über die Ü bereinstimmung in der Struktur und dem Wachstum des Tiere und Pflanzen. W Engelmann: Leipzig No 176, 1839), which recognized the cell as the primary unit of all living organisms. The concept of cellular totipotency, which was inherent in the Cell Theory and forms the basis of plant biotechnology, was further elaborated by Haberlandt (Sitzungsber K Preuss Akad Wiss Wien, Math-Naturwiss 111: 1902), who predicted the production of somatic embryos from vegetative cells. This brief historical account traces the development of technologies for the culture, regeneration and transformation of plants that led to the production of transgenic crops which have become central to the many applications of plant biotechnology, and celebrates the pioneering men and women whose trendsetting contributions made it all possible.

“…It can be said that senescence is less apparent when organization and ontogenetic morphogenesis is less complete. Extrapolation to the cellular level would support this idea, since meristems are capable of indeterminate growth under SD conditions, and in vitro cultures of tissues of other species (Gautheret, 1939;White, 1939) are apparently capable of indeterminate multiplication. On the other hand, only one-celled organism escape senescence (Hartman, 1921;Molisch, 1938;Strehler, 1962).…”
