Plants develop lateral organs such as leaves and flowers throughout their post-embryonic life from a structure called the shoot apical meristem (SAM), located at the plant shoot apex. This process is highly dynamic, and therefore in order to understand meristem and organ development, it is critical to be able to analyze these processes with high temporal and spatial resolution. Although several protocols have been published for imaging the Arabidopsis inflorescence meristem, gaining access to the vegetative meristem for imaging has been considered more difficult. Here we describe a method to dissect young Arabidopsis seedlings in order to obtain a clear view of the vegetative meristem and young leaf primordia using confocal microscopy.
