Fig. 5
The diagram of the chlorophyll metabolism pathway. A The chlorophyll metabolism pathway is presented in a way of successive reaction steps. The circle denotes a chemical compound. The gene name upon the arrow denotes RNA or protein. The normalized gene expression is shown in a box with colors. The direction of the arrow means activation. Colour gradients from green to red represents the Log2FC of the genes. B The chlorophyll concentrations in sugarcane leaves of control and chlorosis samples. Each value represents a sample. The red line indicates the mean value of each group. An unpaired t-test was used to compare the differences between the two groups. p-value = 0.024. ** denotes highly significant. hemA, glutamyl-tRNA reductase; hemL, glutamate-1-semialdehyde 2,1-aminomutase; hemB, porphobilinogen synthase; hemE, uroporphyrinogen decarboxylase; hemF, coproporphyrinogen III oxidase; hemY, protoporphyrinogen/coproporphyrinogen III oxidase; chlH, magnesium chelatase subunit H; bchM, magnesium-protoporphyrin O-methyltransferase; chlE, magnesium-protoporphyrin IX monomethyl ester (oxidative) cyclase; por, protochlorophyllide reductase; DVR, divinyl chlorophyllide a 8-vinyl-reductase; chlG, chlorophyll/bacteriochlorophyll a synthase; CLH, chlorophyllase; HCAR, 7-hydroxymethyl chlorophyll a reductase; NOL, chlorophyll (ide) b reductase; CAO, chlorophyllide a oxygenase
