Morphology of wild-type and sORF-encoded peptide mutant lines. The phenotypes of psep1 KO and PSEP1 OE lines grown on BCD medium with 0.5% glucose: (A,D) wild type; (B,E) knockout of PSEP1; (C,F) overexpression of PSEP1. (G) Diameter of moss plants with overexpression of PSEP1 (Supplemental Fig. S14A–D; Supplemental Table S6). (H) Diameter of moss plants with knockout of PSEP1 (Supplemental Fig. S13A–C; Supplemental Table S6). The phenotypes of psep3 KO and PSEP3 OE lines grown on BCD medium: (I,L) wild type; (J,M) knockout of PSEP3; (K,N) overexpression of PSEP3. (O) Diameter of moss plants with knockout of PSEP3 (Supplemental Fig. S13G–I; Supplemental Table S6). (P) Diameter of moss plants with overexpression of the PSEP3 (Supplemental Fig. S14E–H; Supplemental Table S6). Scale bar: 0.5 mm. P-value was calculated by Student's unpaired t-test. (****) P-value < 0.0001, (***) P-value < 0.001, (*) P-value < 0.05.
