Figure 5.
Expression profile of MtCAMTA genes during the early phase of S. meliloti infection. The expression levels of the MtCAMTA genes were analyzed by qRT-PCR at different time points (6/12/24/48/72 hpi) after S. meliloti infection. The expression levels of MtCAMTA genes in uninfected seedlings were normalized to a value of 1. Each bar represents the mean of five biological replications with standard error. Asterisk denotes significance at P < 0.05 (Student's t-test) compared with the expression levels of MtCAMTA genes in uninfected seedlings.
