Phenotypic differences in transgenic plants of chrysanthemum

Abstract Phenotypic deviations in transgenic plants of chrysanthemum ( Dendranthema grandiflora Tzvelev.) cv. ‘White Snowdon’ carrying either whole pTiB6S3 T‐DNA or the GUS gene construct were evaluated. Morphological differences in comparison with the controls were observed not only in regenerated transgenic plants carrying Agrobacterium tumefaciens B6S3 T‐DNA, but also in transgenic plants carrying the GUS gene. The phenotypic changes were stable through several cycles of clonal propagation.
