Relative transcript values were calculated using plant line f5 as calibrator. However, it has be taken into account that a supergene deposit can form by more than one of the processes described above, and thus hybrid systems are likely to occur. Ps also catalyze the hydroxylation of sesquiterpenes in chicory Cichorium intybus L. Thanks a lot.
