Abstract

Cadmium (Cd) contamination in vineyards necessitates the identification of cultivars that can maintain food safety through metal exclusion. This study investigates the energetic trade-off between vegetative development and molecular detoxification in the ‘Summer Black’ grapevine seedlings. We hypothesized that this cultivar prioritizes survival through a resource-intensive, biphasic defense mechanism at the expense of primary growth. Accordingly, this study assessed bioaccumulation and translocation indices, morphological and physiological characteristics, biochemical indicators, nutritional levels, and targeted gene-expression profiles of 'Summer Black' grapevine seedlings exposed to a Cd gradient (0–20 mg kg⁻¹) for a duration of 28 days. Elevated Cd exposure significantly decreased photosynthetic efficiency, vegetative biomass, and leaf area. Cadmium-treated plants exhibited elevated oxidative stress markers, increased osmolyte accumulation, and enhanced antioxidant enzyme activity. Transcriptional profiling demonstrated that a coordinated, biphasic defense mechanism governs stress alleviation. Mild Cd exposure significantly increased the expression of genes related to xenobiotic detoxification, vacuolar sequestration, and secondary metabolism ( VvGST4, VvABCC1, VvCHS1 ). Conversely, intense Cd stress resulted in a protracted and substantial activation of ROS-scavenging mechanisms ( VvSOD, VvCAT, VvAPX ) to mitigate significant oxidative damage. Regression analysis verified dose-dependent and non-linear responses along the Cd gradient. The roots accumulated the majority of Cd, based on heavy metal partitioning. Transport to aerial tissues was constrained by the translocation factor, which consistently remained below 1.0. Multivariate analysis revealed a systematic conflict between vegetative growth and Cd-induced stress responses, highlighting the energetic trade-off between vegetative growth and stress defense. The ‘Summer Black’ grapevine functions as a "metal excluder," enabling the phytostabilization of contaminated soils instead of phytoextraction. In conclusion, further field studies are required to validate its capacity for Cd immobilization in naturally contaminated vineyard soils.
