Figure 7.
Quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis of transcription levels of the AM symbiosis-related marker genes in pea roots treated with 10−5 M CO5 for 24 h. As a control mock-treated plants were used. The relative expression was normalized against the constitutively expressed ubiquitin and actin genes. Values are means ± SEM of three technical repeats. The graphs show the results of one biological repeat, representative for three biological independent experiments. Asterisks indicate statistically significant differences compared with the respective mock-treated control: *** p < 0.001, * p < 0.05.
