Fig. 4. A 180 bp insertion of the WH1 promoter in Hap1 contributes to its low transcriptional expression and resistance to UVB stress.

a Two haplotypes of WH1 are determined by the presence or absence of 180 bp insertion (red bar) in the promoter region. TSS: transcription start site. b The distributions of the two haplotypes of WH1 in relict and non-relict ecotypes. c WH1 negatively regulates UVB resistance. d Survival rates were collected after 4 days recovery. Data are mean ± SD from independent biological replicates (n = 3), and two tailed t-test was used for significance statistics. e The relative mRNA level of WH1 in two haplotypes. Data are mean ± SD from independent biological replicates (n = 3), and two tailed t-test was used for significance statistics. f Schematic diagram of reporters of transient dual-luciferase assay. LUC: Firefly Luciferase; REN: Renilla Luciferase; NOS: NOS terminator. WH1 promoter fragments (1550 bp) were cloned from Yilong-0 (Hap0) or Tibet-0 (Hap1) genomic DNA. g Transient dual-luciferase assay in N. benthamiana. Data are mean ± SD from independent biological replicates (n = 3). The letters ‘a’ and ‘b’ indicate statistically significant differences by one-way ANOVA Duncan’s test (p = 0.0074, 0.0030, 0.0107, and 0.0042 < 0.05). Source data are provided as a Source Data file.
