^aAll gametophytes were stained 7 days after shooting; each percent represents the average of three replicates; standard error is given in parentheses.^bthe differences between treatments for all pairwise comparisons are statistically significant (z>3.4, P < 0.0003) with the exception of 35S:senseCrChl+pFF19G and senseCrChl+pFF19G.^ctotal number of gametophytes displaying a phenotype and scored.^dthe average of 5 replicates.
