The tetraploid potato genotype Longshu No. 5 seedlings were advised with 500 mmol/L NaCl in the salt-stress experiment. Except for slight blade rolling, which was empiric afterwards 48 h of NaCl stress, Longshu No. 5 looked agnate to ascendancy seedlings developed afterwards NaCl, while astringent abode and bent were empiric in the salt-sensitive genotype Qingshu No. 9 afterwards 24 h (Fig. 1a). To access complete gene announcement advice for the salt-stress acknowledgment in S. tuberosum, we analysed the transcriptome contour of Longshu No. 5 (4 weeks bulb age) developed in tissue boilerplate complete 500 mmol/L NaCl (High alkali group, HS) or 0 mmol/L NaCl (Control group, CK) for 24, 48, 72, and 96 h (Fig. 1b).
Material and schematic of the beginning design. (a) Phenotypes of Longshu No. 5 advised with 500 mmol/L NaCl (HS) or 0 mmol/L NaCl (CK) for 0, 24, 48, 72 and 96 h. Qingshu No. 9 was salt-sensitive control. (b) Schematic assuming the beginning architecture and nine sampling credibility for Longshu No. 5. Plants were calm from three replicates at anniversary time point, and point ① is Longshu No. 5 at the 0 h time point.
RNA was extracted from the salt-treated bulb samples (HS groups; 24, 48, 72 and 96 h) and the basic samples (CK groups; 0, 24, 48, 72 and 96 h) with three replicates per time point (total of 27 samples). The extracted RNA was complete to be of acceptable affection (Supplementary Fig. S1; Supplementary Table S1). Subsequently, 27 libraries were complete and sequenced application the Illumina HiSeqX10 belvedere with the 150-cycle paired-end sequencing protocol26. Through clarification raw abstracts and assessing quality, an boilerplate of 11.74 G apple-pie bases (77.89 actor paired-end reads) per sample were obtained. The Q30 allotment (the admeasurement of bases with a affection amount greater than 30) was 95%–97%, and added than 84.4% of the RNA-seq reads could be mapped to the DM advertence genome (Supplementary Table S2).
