Figure 7. Variation of expression of LbGAP and LbGAPy.
PCR experiments were performed on genomic DNA (+) to assess the specificity of the LbGAP- and LbGAPy-specific primers, and on serial dilutions of cDNA templates (1, 1/10, 1/100) to determine whether the variation of expression of LbGAP and LbGAPy is under the control of cis- or trans-acting elements. The ITS2 ribosomal sequence was used as control to assess the quantity of the DNA and RNA samples. (−) Negative control.
