Fig. 2From: Overexpression of PvCO1, a bamboo CONSTANS-LIKE gene, delays flowering by reducing expression of the FT gene in transgenic ArabidopsisPhylogenetic tree of COL proteins in Arabidopsis thaliana, Oryza sativa, Ph.violascens and Ph. heterocycla. Bootstrap analysis (1000 replicates) was performed to assess the support of each branch. Accession numbers of the CO proteins used to construct the phylogenetic tree are listed in Additional file 3: Table S3Back to article page
