Identification of the CsWRKY7 in transgenic Arabidopsis. (A,B) Overexpression of CsWRKY7 delayed Arabidopsis flowering in different developmental stages: (A) Representative photographs of 25-day-old-plant of WT and transgenic lines (L8, L10, and L14) growing in normal conditions. (B) 35-day-old-plant. Each line included four seedlings. Experiments were performed in five biological replicates. (C) Expression patterns of flowering-related genes in CsWRKY7-overexpressing and wild type Arabidopsis. Leaf samples were harvested from 25-day-old transgenic lines and WT. The error bars indicate the means ± S.E. (n = 5), * indicates that the differences are significant (p < 0.05), ** indicate that the differences are highly significant (p < 0.01).
