The early senescence phenotype of the serk4-1 mutant; (A) the leaf senescence phenotype of the five-week-old serk4-1 mutant and the wild-type plants; (B) phenotype of 12 detached rosette leaves from the serk4-1 mutant and the wild type; (C) The Fv/Fm of the serk4-1 mutant and the wild type; (D) the chlorophyll content of the serk4-1 mutant and the wild type; (E) the ion leakage of the serk4-1 mutant and the wild type; (F) the expression levels of SAG12 and RBCS in the number 6 rosette leaf of the serk4-1 mutant and the wild type. The ratios of SAG12 and RBCS gene expression level were calculated relative to the wild type, respectively. WT, wildtype. In D, E and F, the data are means ± SD of three biological repeats. *** p < 0.001 (t-tests).
