After 2 weeks cultivation in liquid MS medium, cucumber hairy roots were collected. Untransformed, sterile cucumber seedlings and hairy roots induced by wild-type
A. rhizogenes 15834 were used as controls. LA, LC and
DLC (Fig. 1) were used as a substrate for determination of
CGH activity. The activity of the rcgh-transformed hairy
roots was in all cases higher as that of hairy roots induced
by wild-type A. rhizogenes 15834
