Topping and grafting affect the alkaloid content and gene expression patterns of tobacco (Nicotiana tabacum L.).

ABSTRACT: In this study, we aimed to determine molecular mechanisms underlying the effects of topping and grafting in tobacco (Nicotiana tabacum L.) by comparing the alkaloid contents and enrichment pathways of differentially expressed genes (DEGs) among plants subjected to different combinations of topping and grafting treatments. Plants of the tobacco variety "Zhongyan 100" and eggplant (Solanum melongena L.) were grafted in four combinations as scions and rootstocks, respectively. The four treatment groups were tobacco with topping, tobacco without topping, topped tobacco grafted onto an eggplant rootstock, and non-topped tobacco grafted onto an eggplant rootstock. Tobacco leaves were collected on the day of topping, at 7 days after topping, and after flue curing, the alkaloid conte
