Functional validation of FZP in B. distachyon. FZP mutant screening identified two alleles with independent mutations (Bd8202 and Bd8972) located in the AP2/ERF domain (A), both exhibiting SSs not present in the wild type (WT, Bd 21-3; B). B. distachyon fzp mutants and wild-type plants show similar growth and architecture (C, left). Spikes with different penetrance of the SS phenotype can be observed in mutants (C, right; stars indicate SSs). D, Spikes in fzp mutants show spikelets with a single pedicel as observed in the wild type but with dichotomous or trichotomous rachilla.
