What method is used to make golden rice Plasmid Vector or Biolistic?

Golden rice is primarily developed using a plasmid vector method, specifically through genetic engineering techniques. Scientists introduce genes that encode for beta-carotene biOSynthesis into the rice genome using plasmids, which are circular DNA molecules. Although biolistic methods (gene gun) can also be used for plant transformation, plasmid vectors are more commonly employed for creating genetically modified crops like golden rice.
