RNA-sequencing Reveals Global Transcriptomic Changes in Nicotiana tabacum Responding to Topping and Treatment of Axillary-shoot Control Chemicals.

ABSTRACT: Removal of terminal buds (topping) and control of the formation of axillary shoots (suckers) are common agronomic practices that significantly impact the yield and quality of various crop plants. Application of chemicals (suckercides) to plants following topping is an effective method for sucker control. However, our current knowledge of the influence of topping, and subsequent suckercide applications, to gene expression is limited. We analyzed the differential gene expression using RNA-sequencing in tobacco (Nicotiana tabacum) that are topped, or treated after topping by two different suckercides, the contact-localized-systemic, Flupro(®) (FP), and contact, Off-Shoot-T(®). Among the differentially expressed genes (DEGs), 179 were identified as common to all three conditions. DEGs, largely
