美国农业研究服务局的两位植物遗传学家沃特金和路德,首次在大豆基因中发现了可移动的成份。可移动基因又称为“跳动基因”,它们能改变在染色体上的位置。由于基因的这些可移动成份能在有机体的DNA(脱氧核糖核酸)中移动,因而可嵌入基因并创造出突变。如果突变是可以观察到的,如异常的矮株或高株,花色或其它性状的变异,遗传学家就可以知道可移动基因嵌入了控制这一性状的基因。 Two plant geneticists from the U.S. Agency for Agricultural Research Services, Watkins and Luther, first discovered a moveable ingredient in soybean genes. Movable genes, also known as “beating genes,” alter their location on chromosomes. Because these mobile components of a gene can move in the organism’s DNA (DNA), the gene can be embedded and mutations can be created. If mutations are observable, such as aberrant dwarf or tall plants, variations in flower color or other traits, geneticists know that the transgene is embedded with the gene that controls the trait.
