Nicotiana tabacum cultivar:Yunyan 87 Raw sequence reads

Tobacco (Nicotiana tabacum) is a valuable industrial and commercial crop, and the leaf is its primary product. Topping (removing terminal buds) is a common agronomic practice that significantly improves the yield of tobacco leaves. Potassium (K+) plays an important physiological role in tobacco growth and leaf traits, including combustibility, aroma and safety in cigarette products, and its levels are significantly decreased after topping. Here, to present global spatial-temporal gene expression profiles and gene regulatory networks of the core elements of potassium uptake, leaves and roots from topped and intact plants at short- and long-term time points after topping were sampled for transcriptome analysis.
