PLANT BIOTECHNOLOGY APPLIED TO HORTICULTURAL CROPS |

| Abstract:
All artificial manipulation made on a plant, or only on a part of a plant, could refer to "plant biotechnology". In our review, we shall separate the numerous plant biotechnology applications into two groups. The first group is related to tissue culture and go from a single cell, or a specific tissue, to the whole plant. These technologies are founded on a very old concept "the cellular totipotency", stated by Haberlandt (1902), but only demonstrated by Steward in 1958. His research team was the first to be able to transform a carrot cell line in some "artificial embryos", later called "somatic embryos". The applications of the second group are more recent and derive from on excellent knowledge of the double helicoidal DNA structure proposed in 1953, by James Watson and Francis Crick. They base their strategy on the molecular biology science. | |
