Transcriptome dataset for comparative analysis of differentially expressed genes between wild type and transgenic potato plants overexpressing Nuclear Factor Y subunit A7.

Nuclear Factor Y (NF-Y) is divided into three different types of subunits, A, B, and C. NF-Ys play crucial roles in plants for controlling gene expression associated with various developmental processes and abiotic stresses, but it is mostly unknown the downstream genes regulated by NF-Ys in plant. One of the potato NF-Y genes, , increased potato's drought tolerance when overexpressed under the control of constitutive promoter. Therefore, it was of interest what genes are regulated by the increased expression level of . To investigate the downstream genes of , the transcriptome sequencing was carried out for four potato lines, including L 'Superior' as wild type (WT), empty vector control (VC), and two overexpressor lines (designated to #19 & #26). The RNA sequencing data was produced by the Illumina NovaSeq 6000 sequencing system. The number of total raw reads obtained from the RNA sequencing was 36.7 million for WT, 36.2 for VC, 29.3 for StNF-YA7 #19, and 29.5 million for #26, respectively. The length of total raw reads for each sample was between 5.92 Gb ( #19) and 7.42 Gb (WT), and after filtering raw quality reads, the total length was between 5.81 Gb ( #19) and 7.29 Gb (WT). Each filtered clear read set of four transcriptomes was mapped on the potato reference genome, SolTub_3.0, and the percentage of mapped reads ranged from 89.8 % (VC) to 90.3 % (WT). GC contents range between 43.01 % ( #19) and 42.44 % ( #26). Q20 quality score ranges between 98.63 % ( #26) and 98.74 % (VC).
