“…The results obtained here are consistent with earlier findings [7,11,31,32]. However, Carrier et al [33] reported that approximately 80% of Cd was found predominantly in the soluble fraction, and relatively little Cd was found in the cell wall (11%).…”

“…The high Cd concentrations of the toxic forms of Cd in the cell organelles could seriously damage the cells and the metabolic processes in plants [7]. In the present investigation we observed that the proportion of CdE and Cdw in roots is low when compared with the other Cd chemical forms.…”

“…CdNaCl represents 42% (10 μM Cd), 44% (50 μM Cd), and 32% (100 μM Cd). It was demonstrated that NaCl extractant binds to proteins and pectic acids, with Cd being fixed by pectic acids [7]. Vacuolar sequestration and cell wall binding play a major role in hyperaccumulation of heavy metals [8].…”

“…The cell wall is the first barrier protecting the protoplast from Cd toxicity because it is composed of polyoses and protein [42]. As Cd has a strong affinity to proteins or sulfhydryl compounds (-SH) and other side chains, it can easily combine with proteins [5] and disturb enzyme activity [7]. It was reported that the cell wall played a role in metal tolerance when the cell wall volume was high compared to the cytosol and vacuole [43].…”

“…Nonessential metals accumulated in the cell wall and vacuole is another detoxification process that prevents them from entering more sensitive cell metabolic sites [7]. The vacuole can be considered the most important component in the soluble fraction of a cell [8].…”

BACKGROUND Cadmium (Cd) contamination in farmland is a serious environmental and safety issue affecting plant growth, crop productivity, and human health. This study aimed to investigate genotypic variation in root morphology and Cd accumulations under moderate Cd stress among diverse maize genotypes. Twenty maize genotypes with contrasting root systems were assessed for Cd tolerance 39 days after transplanting (V6, six‐leaf stage) under 20 μmol L−1 CdCl2 using a semi‐hydroponic phenotyping platform in a glasshouse. RESULTS Cadmium stress significantly inhibited plant growth across all genotypes. Genotypic variation in response to Cd toxicity was apparent: shoot dry weight varied from 0.13 (genotype NS2020) to 0.35 g plant−1 (Dongke301) with deductions up to 63% compared with non‐Cd treatment (CK). Root dry weight of 20 genotypes ranged from 0.06 (NS2020) to 0.18 g plant−1 (Dongke301) with a deduction up to 56%. Root length ranged from 2.21 (NS590b) to 9.22 m (Dongke301) with a maximal decline of 76%. Cadmium‐treated genotypes generally had thicker roots and average diameter increased by 34% compared with CK. Genotypes had up to 3.25 and 3.50 times differences in shoot and root Cd concentrations, respectively. Principal component and cluster analyses assigned the 20 genotypes into Cd‐tolerant (five genotypes) and Cd‐sensitive (15 genotypes) groups. CONCLUSIONS Maize genotypes varied significantly in response to moderate Cd stress. Cadmium‐tolerant genotypes optimized root morphology and Cd accumulation and distribution. This study could assist in the selection and breeding of new cultivars with improved adaptation to Cd‐contaminated soil for food and feed or land remediation purposes. © 2022 The Authors.
