Figure S1. Validation of gene expression levels in Ler and dyt1 anthers using RT-PCR and real-time PCR.
(a) RT-PCR of DYT1-regulated genes. UBQ1 was used as an internal control. (b) Real-time PCR of 7 genes
coding for enzyme and 9 genes encoding transcription factors down-regulated in dyt1. Normalized
expression levels in Ler were set to 1 when compared with those in dyt1.
Figure S2. DYT1 binds to gene promoter sequences containing the consensus binding site. (a) Probes
(oMC6808-oMC6819) representing promoter regions containing TCACGTGA sites. Putative binding sites
are underlined. (b) Gel shift assay demonstrating that DYT1 could bind to pMS1 (positive control) and
probes listed in (a).
Figure S3. MYB35-RNAi abnormal anthers and MYB35-SRDX normal male meiosis. (a-e) Wild-type (WT)
anthers. (f-j) Anthers from the MYB35-RNAi transgenic plant. (a) WT anther showing stained mature
pollen grains. (f) MYB35-RNAi anther lacking stained pollen grains. (b-e) WT anthers of stage 6-9. (g-j)
MYB35-RNAi anthers of stage 6-9. (k-o) WT and (p-t) MYB35-SRDX male meiosis. Prophase I (k, p),
metaphase I (l, q), anaphase I (m, r), anaphase II (n, s), and telophase II (o, t). MYB35-SRDX shows no
obvious abnormal phenotype in meiosis. Scale bars, 50 m in (a) and (f); 10 m in (b)-(e) and (g)-(j); 10
m in (k)-(t).
