Phenotypic deviations in transgenic plants of chrysanthemum (Dendranth
ema grandiflora Tzvelev.) cv. 'White Snowdon' carrying either whole pT
iB6S3 T-DNA or the GUS gene construct were evaluated. Morphological di
fferences in comparison with the controls were observed not only in re
generated transgenic plants carrying Agrobacterium tumefaciens B6S3 T-
DNA, but also in transgenic plants carrying the GUS gene. The phenotyp
ic changes were stable through several cycles of clonal propagation.
