| abstract |
This invention discloses a novel process and vector therefore for producing a multicellular plant or plant cells having stably transformed plastids. This process comprises transforming plastids or plant cells via homologous recombination with a DNA molecule enabling DNA modification, whereby said DNA molecule comprises a fragment of a gene requiring for expression a sequence element of the host plastid. The invention also includes the use of novel selection inhibitors for plastic transformation and the possibility of performing multiple rounds of transformation without accumulation of resistance genes. |
