High expression of ClTST2 increases sugar accumulation. ClTST2-specific mRNA relative levels determined by qRT-PCR in the mature fruit of 96 RILs (A) and 50 core germplasm accessions (B) selected from Supplemental Table S4. Basta resistance in seedling stage (shown in red circles) and fruit phenotype at 30 DAP for transgenic control (C) and representative ClTST2 overexpression T1 lines (D and E). In lines ClTST2 OE-2 and ClTST2 OE-5 with higher levels of ClTST2 mRNA, the fruit sugar contents increased significantly compared with the control (F).
