Transcriptional analysis on the effect of the overexpression of VvSUC11,VvSUC12,or VvSUC27 in tomato on the growth of fruit

Purpose: We used transcriptome sequencing to study the regulated mechanism of VvSUC11,VvSUC12,or VvSUC27 on tomato fruit growth. Methods: the 35S:: VvSUC11, VvSUC12, and VvSUC27 constructs were introduced into transgenic tomatoes (Micro-Tom) by the Agrobacterium-mediated transformation, 5 DPA (days after anthesis) fruit was collected, 3 replicates per group. Extract total RNA, detect RNA quality, library preparation, sequencing, and analyze data. Results:Reads were obtained for each sample using Illumina Hiseq X Ten sequencing. After discarding the low-quality reads, corresponding to over 40 million clean reads obtained from sequencing were mapped on the reference genome of Solanum lycopersicum. High Pearson's correlation coefficients of FPKM distribution between the three biological replicates for each sample were detected (1> R2 > 0.99, P < 0.001) , reflecting the robustness of our library preparation from tomato RNA samples. Compared with WT lines, there were 2459 DEGs in the VvSUC11-overexpressing lines, of which 1283 genes were upregulated and 1176 genes were downregulated. Whereas, there were 1369 DEGs in VvSUC12-overexpressing lines, including 544 upregulated and 825 downregulated genes. In the meanwhile,there were 1777 DEGs in VvSUC27-overexpressing lines, including 623 upregulated and 1154 downregulated genes. Overall design: Deep-sequencing using Illumina, in triplicate, yielded 5 DPA tomato fruit mRNA expression profiles from WT lines, VvSUC11-, VvSUC12-,and VvSUC27-overexpressing lines.
