Figure 3. Transient expression of LSL-GUS gene in wild type Arabidopsis (cv. Columbia) either with or without Rep expression. Control is water treated leaf samples while Agrobacterium strain LBA4404 is used as a negative control. pBY031 was mixed with Agrobacterium harboring pBY003, pREP110, or p∂REP110. Leaf samples were harvested 1 and 3 DAI, and GUS enzymatic assay was performed.
