Fig. 1From: Genome-wide survey of the phosphofructokinase family in cassava and functional characterization in response to oxygen-deficient stressPhylogenetic relationship of PFK genes from cassava and four other species. The NJ tree was constructed with PFK proteins from cassava, Arabidopsis, potato, rice and castor bean using the Muscle programme of MEGA7 software with 1000 bootstraps. PFK protein was classified into two groups and five subgroups. The five subgroups are indicated with different background coloursBack to article page
