Flowering is one of the most important biological phenomena in the plant. Pea (Pisum sativum) is a typical genetic experiment material, and flowering is one of its very important traits. In this study, we performed the identification and comprehensive comparative analysis of flowering genes from Pisum sativum and other 836 sequenced plant genomes. We established an extensive angiosperm flowering atlas, encompassing a staggering 183,720 genes across eight pathways, along with 10,155 ABCDE mode genes. An interaction network between flowering genes of the ABCDE model and corresponding upstream genes offered a blueprint for their regulatory mechanisms. Moreover, we explored the miRNAs and target genes linked to the flowering processes of each plant. Finally, we constructed a user-friendly web interface, the 'Plant Flowering-time Gene Database' (PFGD, http://pfgd.bio2db.com/). We believe that this database will serve as a cornerstone in the global research community related to the plant flowering, facilitating the in-depth exploration of flowering-time genes in the plants.
