A composite view of 50 genes involved in meristem development and their main pathways aggregated from literature review. Genes characterized in A. thaliana are shown with a green background. Genes with known orthologs in A. thaliana and S. lycopersicum are in orange background. Genes initially characterized in S. lycopersicum are in a red background. Genes not involved in this study are shown with a grey background. Red arrows suggest a negative feedback between two gene entities. Grey arrows suggest activation. Colored circle highlight multiple genes from the same family (HD-ZIP, YABBY, LRR and SNF2). For candidate genes references, see Table 2.
