摘要: Summary Inflorescence architecture is one of the most important agronomical traits. Characterization rice aberrant panicle organization 1 (apo1) mutants revealed that APO1 positively controls spikelet number by suppressing precocious conversion inflorescence meristems to meristems. In addition, associated with regulation plastchron, floral organ identity, and determinacy. Phenotypic analyses apo1 homeotic double demonstrate regulates class-C genes, but not class-B genes. Molecular studies encodes an F-box protein, ortholog Arabidopsis UNUSUAL FLORAL ORGAN (UFO), which a positive regulator Overexpression caused increase in branches spikelets. As mutant inflorescences flowers differed considerably between ufo, functions UFO appear have diverged during evolution.
