Existng inequalities in the world pattern of plant germplasm exchange (1) are associated with the way Wastern acience spread in the New Worly and (2) have always been shaped by strategies influenced by the level of development of science over time. The paper puts in historical perspective the struggle for control over plant genetic resources (1) from the Great ColumbianExchange, suported by economic botany, (2) to the Green Revolition, suported by Mandelian genetics, (3) to the  Biorevolution, suportedby molecular genetics. The introductio of equal procedures for plant intellectual property protection worldwide will(1) further the contradictions which already exist in North-North, North-South and South-South agricultura-related relations and (2) open up the possibility for the commodification of nature in the 21st century.  abreeding  aGenética  aMelhoramento  aPesquisa  aPlanta  aAspecto politico-economico  aGenetic  aGermoplasm  aPlant  aPolitic-economy aspects  aResources
