Web1 aug. 2024 · Plants have two types of meristems, as described below: Apical meristem: located at the tip of the shoot and the tip of the root. The apical meristem lengthens up and down. It is responsible for primary growth. Lateral meristem: located at branches to increase plant girth. It is responsible for secondary growth. Angiosperm Body Plan WebGenes that control switches in meristem identity Several genes identified through mutant analysis control the progressive specifi-cation of axillary meristem identity on the flanks of the inflorescence meristem. The switch from producing long branches to short branches (spikelet pairs) is controlled, in part, by ramosa1 (ra1). The ra1mutant blush cardigan bath and body works
