The shoot apical meristem (SAM) is a complex organ responsible for the development of all above-ground structures. In the SAM, transcriptional activation of transposable elements (TEs) has been reported. This transcriptional activation of TEs during has also been reported in late reproductive stages, where it has been linked to epigenetic reprogramming, imprinting and transposon control in the germline. However, its consequence during meristem progression remains largely a mystery. My goal is to investigate this phenomenon using the tomato vegetative meristem as a model. High Throughput Sequencing data analysis will reveal possible effects and interactions of transcriptionally activate TEs with the transcriptome and the epigenetic machinery.
