Gene Transfer in Woody Plants: Perspectives and Limitations

  • Chapter
Somatic Cell Genetics of Woody Plants

Part of the book series: Forestry Sciences ((FOSC,volume 30))

Abstract

Conventional and more recently unconventional methods have been employed for transfer of genes in plants. Hybridization involving backcrosses has been effectively utilized in plant species for transfer of specific genes. However, this procedure takes too long, and would be impractical in long-lived tree species. By employing unconventional approaches involving Agrobacterium mediated gene transfer, or by direct gene transfer, transgenic plants have been produced in a number of plant species, including a tree species Populus. Dominant selectable markers (kanamycin resistance), herbicide tolerance and insecticidal genes, originally cloned from bacteria, have been transfered and expressed in plants. In some cases the transmission of the foreign genes to the progeny has been demonstrated. Unexpected genetic variability may be associated with foreign gene transfer in plants. This variability may be a cause of concern in long-lived tree species, following foreign gene transfer. Perspectives and limitations of foreign gene transfer will be discussed in plants, in particular tree species.
