PlantCFG, a multi-species plant candidate flowering gene database, contains 112 species from 10 plant families. We performed a careful literature survey and 459, 71, and 112 reported flowering genes were curated in Arabidopsis thaliana, Glycine max, and Oryza sativa, respectively. The candidate flowering genes in other species were identified by using a combination of sequence similarity and conserved domain based approaches. It contains 82,104 candidate flowering genes, which were classified into 372  protein classes and 62 gene families. PlantCFG aims to collect, organize, display and compare flowering genes in multiple plants, including the following: (i) query the basic information of candidate flowering genes in 112 plants; (ii) explore the functions of genes involved in the ‘ABCDE’ model; (iii) carry out collinearity relationship, phylogenetic, sequence identity, and K_a/K_s analyses of candidate flowering genes in different species; and (iv) browse, search and batch download flowering gene lists and sequences. Furthermore, we provide a Submit module, where users can submit flowering gene, which will be reviewed and periodically updated to the database.

Notice

(i) The lists provided here are candidate flowering genes inferred from orthologous groups which DO NOT represent flowering genes from experimental work (in most species);
(ii) That most flowering time regulatory pathways in distant groups are likely to involve different genes, and that positive flowering time regulators in some species could have an opposite function in others.
