SlCBL10 gene is involved in maintaining a suitably low Na⁺/Ca²⁺ ratio in tomato apex and flower under salinity conditions. Wild-type, Slcbl10 mutant, and RNAi SlCBL10 plants grown in a hydroponic system and salt-treated at the fifth fully developed leaf stage (HSTa assay). Na⁺ (A) and Ca²⁺ contents (B) were analyzed in upper adult leaf, apex and flower after 6 DST, and then the Na⁺/Ca²⁺ ratio was calculated (C). Values are the mean ± se of two independent assays, each with three biological replicates. Different lowercase letters represent significant differences (P > 0.05) calculated by ANOVA. D, Representative images of wild-type and Slcbl10 mutant flowers after 10 DST.
