Ratooning rice is an economical alternative to the second seasonal rice, thus increasing the yield of ratooning rice is highly important.<h4>Results</h4>Here we report an applicable transgenic line constructed through the manipulation of <i>osa-MIR156f</i> expression in rice shoot using the <i>OsGA3ox2</i> (<i>D18</i>) promoter. In seasonal rice, the D18-11 transgenic line showed moderate height and more effective tillers with normal panicle. In ratooning rice, axillary buds outgrew from the basal node of the D18-11 transgenic line before the harvest of seasonal rice. More effective tillers produced by the outgrowth of axillary buds contributed to the plant architecture improvement and yield inBiological procedures onlineManipulating <i>osa-MIR156f</i> Expression by <i>D18</i> Promoter to Regulate Plant Architecture and Yield Traits both in Seasonal and Ratooning Rice.PMC68272589131731231570372Xiao LZhu YWang RLiu QGaballah MSu YHong BPeng KfalseManipulating <i>osa-MIR156f</i> Expression by <i>D18</i> Promoter to Regulate Plant Architecture and Yield Traits both in Seasonal and Ratooning Rice.<h4>Background</h4>Rice (<i>Oryza sativa</i> L.) feeds more than half of the world's population.
