Description Rice frizzy panicle (fzp) mutants don't form floret, but produce sequential rounds of branching and several rudimentary glumes are formed in each ectopic branch. The FZP gene was isolated by transposon tagging, it encodes an ERF transcription factor and is the rice ortholog of the maize BD1 (BRANCHED SILKLESS 1) gene. FZP expression is restricted to the time of rudimentary glumes differentiation in a half-ring domain at he base of which the rudimentary glume primordium emerged. The function of FZP is suggested to prevent the outgrowth of the axillary meristem within the rudimentary glume and maintain the transition from spikelet to floral meristem identity.
