Comparably High Transcript Levels in Independent Transgenic Lines Harboring Two Copies of a Particular Reporter Gene under the Control of the CaMV 35S Promoter.

RNA gel blot analyses of plants carrying GUS ([A] and [B]), SPT (A), or GFP (B) genes. Hemizygous plants were assayed for line GUS 2xf 113; in all other cases, 8-week-old homozygous plants were examined. The blots were hybridized with a probe corresponding to the ocs3′ end and with a probe derived from Arabidopsis actin genes 2 and 8 (An et al., 1996).
