Fig 4. RT-PCR analysis of selected differential splicing events in mpk4 and WT in mock- or flg22-treated plants.

RT-PCR was performed on 3 biological replicates and products were separated on the same gel. A black arrow marks the position of the alternative isoforms. Band intensity was normalized against the non-differential isoforms. Significant differences were calculated by t-test (*: p-value < 0.05).
