 Although oni1 showed organ fusions as is the case in Arabidopsisfdh, the oni1 mutants lacked a normal outermost cell layer (layer 1 or L1) and failed to maintain the shoot apical meristem (SAM).

	ONI1 gene is originally derived from Oryza sativa Japonica Group(cultivar: Nipponbare). It encodes an fatty acid elongase involved in the synthesis of very-long-chain fatty acids, which are the component of extracellular waxes<ref name="ref2" />.

	It's the key gene for correct acid composition and normal shoot development in rice. Mutation of ONI1 will induce a reduced amount of very-long-chain fatty acids<ref name="ref1" /> and failure of the maintenance of SAM and ectopic expression of SAM-specific KNOX genes in leaf. ONI1 was specifically expressed in the outermost cell layer of the shoot apical meristem and developing lateral organs. These results show that fatty acid elongase is required for formation of the outermost cell layer, and this layer is indispensable for entire shoot development in rice<ref name="ref3" />.
