Phenotypes of transgenic plants overexpressing sORFs. (A) WT plant. (B) Mutant overexpressing sORF5491 showing a large adult plant phenotype. (C) Mutant overexpressing sORF5634 showing a small adult plant phenotype. (D) Overexpression of sORF3416 resulted in a pale green leaf phenotype. (E) Overexpression of sORF2813 resulted in a bent stem phenotype. (F) Overexpression of sORF5697 resulted in a penta-petal phenotype, whereas most WTs have tetra-petals. GO categories of biological process (G) and molecular function (H) with overrepresented numbers of coexpressed genes for 49 coding sORFs with phenotypic effects. Arrowheads point to subcategories. Red circles indicate categories with significantly (χ² test, FDR < 0.05) more genes among the coexpressed genes.
