Relative gene expression of the three expressed Bna.SRR1 copies in emerging and developed leaves and petioles in the accessions Manitoba (winter-type) and Korall (spring-type) without vernalization from rosette material with approximately 5 developed leaves. (a) Emerging leaves, (b) developed leaves, (c) petioles. The values were calculated from RT-qPCR using the ΔCt method and represent mean of 3 biological replicates. Error bars show standard error of mean. Asterisks show the level of significance based on the Student’s t-test (*p-value< 0.05, **p-value< 0.01, ***p-value< 0.001)
