International ClassesC12N 015/00A01H 001/00 A01H 001/02 AbstractA novel method for efficiently carrying out pollen-mediated gene transformation of flowering plants is described. Utilizing novel DNA constructs incorporating exogenous DNA fragments coding for specific enzymes, the method can product transformed plants exhibiting novel, useful traits. Confirming hybridization tests have been carried out to identify the exogenous DNA transformed into the plant.Other References
