Gene expression and genetic complementation analyses of MTP11 gene copies in Arabidopsis and A. lyrata. A, Organ expression patterns of the two A. lyrata MTP11 homologous genes assessed by RT-qPCR analysis. B, Genetic complementation of the Arabidopsis mtp11 loss-of-function mutant with AL.MTP11A and AL.MTP11B gene copies. Seedlings were grown on Murashige and Skoog medium (1% Suc, 1× Murashige and Skoog medium, and 1.2% phytoagar) for 8 d and then transferred to agarose medium supplemented with 2 mm Mn2+. As predicted by the expression data, both homologs could complement the mutant phenotype. WT, Wild type.
