Extended Data Figure 9. Controls for the regulation of RP gene expression experiments.

a–i, Expression of the indicated genes in the leaves of independent transgenic lines was monitored by qRT–PCR. a, LIMYB expression in the limyb-32 mutant was examined. b, LIMYB expression in limyb-32 mutant restores wild-type expression of the RP genes. Expression of the S13a, L18A and L28e genes was monitored in three independently transformed limyb-32 knockout plants with the LIMYB gene. c–f, Expression of the unrelated gene AtWWP1 was monitored as a negative control in three independently transformed LIMYB-, RPL10- and T474D-overexpressing lines in addition to the limyb-32 mutant. g, The double-mutant inactive kinase, G4743V/T474A, does not downregulate the RP genes. The transcript accumulation of the indicated RP genes was quantified by qRT–PCR in two independently transformed nik1 knockout lines expressing the G4743V/T474A double mutant. h, i, Expression of LIMYB (h) and the transgene T474D (i) was monitored in the limyb-32 lines, which were transformed with T474D. a–i, Means ± 95% confidence intervals (n = 3) based on bootstrap resampling replicates of three independent experiments are shown.
