|a Cadmium (Cd) toxicity is a form of soil contamination that causes losses in plant growth and yield. Understanding the effects of Cd-induced changes in physiological and cellular processes will help scientists develop better scientific strategies for sugar beet plant improvement. Cd toxicity triggered a substantial decrease in morphological parameters and total soluble protein in sugar beets, as well as membrane damage and cell death. Furthermore, the SPAD score and photosynthetic OJIP parameters in leaves were severely affected due to Cd stress. This was correlated with the decreased FCR activity and BvIRT1 expression in roots, suggesting the adverse effect of Cd in Fe acquisition in sugar beet. Our findings also revealed that BvHMA3 and BvNRAMP3 were upregulated in Cd-exposed roots, indicating that these genes might be involved in Cd uptake in sugar beet. In silico analysis of BvHMA3 and BvNRAMP3 proteins showed close partnerships with several Arabidopsis genes mainly linked to metal tolerance protein, cation diffusion facilitator, vacuolar metal transporter, and vacuolar Fe transporter. Subsequently, Cd-exposed sugar beet showed severe sensitivity to oxidative damages resulted in elevated H2O2 and O2.- without possessed efficient antioxidant defense. Finally, growth retardation in Cd-exposed sugar beets is linked to photosynthetic inefficiency caused by low Fe levels and oxidative stress in cells. These results may be used to improve Cd-sensitive sugar beet plants by breeding or transgenic programs
