“…Hence, plants must see and react to changes in their surroundings and adjust to water shortages in order to survive and thrive. Plants have developed intricate mechanisms to respond to drought stress in order to sustain optimum development under circumstances of water scarcity [38,39] N. tabacum is an important economically crop, plant bioreactor and model plant for biological study grown in more than 120 countries [23,40]. N. tabacum exhibits a significant requirement for water during its reproductive phase, with varying levels of demand observed across different stages of reproduction [26,41].…”

The development and growth of plants are significantly impacted by adverse surroundings, particularly drought conditions. The yield and quality of plants, in particular, are heavily reliant on the presence of favorable growth conditions. Here, we performed comprehensive research to investigate phenotype, physiological characteristics, transcriptomic and metabolomic changes in Nicotiana tabacum (N. tabacum) in responses to drought stress (DS). This work aimed to investigate the detailed responses of N. tabacum to DS under different drought conditions (CK, well-watered; LD, light drought; MD, moderate drought and SD, severe drought). N. tabacum grew normally under CK but was inhibited under LD, MD and SD stress; the relative water content, transpiration rate and protective enzyme activity significantly influenced under DS. In the LD/CK, MD/CK and SD/CK comparison groups, there were 7483, 15558 and 16876 differentially expressed genes (DEGs), respectively, and 410, 485 and 523 differentially accumulated metabolites (DAMs), respectively. The combined analysis of transcriptomic and metabolomic data unveiled the significant involvement of phenylpropanoid biosynthesis in the N. tabacum's response to drought stress. These findings characterized the key metabolites and genes in responses to drought stress in N. tabacum, hence offering valuable insights into the underlying mechanisms driving these responses to DS and maintaining plant health under climate change.
