Name fzp (GENE SYMBOL)
Synonyms (4)
GRAMENE GENEGR:0060339
Type Gene
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
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.
