Unrooted NJ tree of Gossypium spp. PHYC -related genes based on a 1022 bp consensus alignment of amplification products from primers PHYdeg-F and PHYC_1R_DFCI. Distances (uncorrected "p") and most parsimonious number of nucleotide changes are indicated for each branch (to the left and to the right of the/, respectively). Bootstrap support (500 replicates) is indicated where >50%.
