• Key message
  • Simultaneous knockdown of the four rice SEP-like genes OsMADS1, OsMADS5, OsMADS7 and OsMADS8, leads to homeotic transformation of all floral organs except the lemma into leaf-like organs
  • In case of the loss-of-function mutation of OsMADS5, no defect in either panicles or vegetative organs was observed
  • Genetic and molecular analyses demonstrated that OsMADS1, OsMADS5 and OsMADS34 together regulate floral meristem determinacy, and specify the identities of spikelet organs by positively regulating the other MADS-box floral homeotic genes
  • Experiments conducted in yeast also suggested that OsMADS1, OsMADS5 and OsMADS34 form protein-protein interactions with other MADS-box floral homeotic members, which seems to be a typical, conserved feature of plant SEP proteins
  • OsMADS5 was expressed strongly across a broad range of reproductive stages and tissues
  • Our results reveal a role for OsMADS5 in panicle development, and show that OsMADS5 and OsMADS34 play similar functions in limiting branching and promoting the transition to spikelet meristem identity, in part by repressing RCN4 expression
  • We have generated loss-of-function and overexpression mutants of the paralogous OsMADS5 and OsMADS34 genes in rice (Oryza sativa), and analysed their panicle phenotypes
  • The osmads5 osmads34 mutant lines had significantly enhanced panicle branching with increased secondary, and even tertiary and quaternary, branches, compared to wild-type (WT) and osmads34 plants
  • Rice SEPALLATA genes OsMADS5 and OsMADS34 cooperate to limit inflorescence branching by repressing the TERMINAL FLOWER1-like gene RCN4.
