Aluminum (Al) toxicity in acidic soils poses significant challenges to crop growth and development. However, the response mechanism of Shatian pomelo (Citrus maxima ‘Shatian Yu’) roots Al remains poorly understood. This study employed root phenotype analysis, physiological index measurement, transcriptome quantitative PCR (qPCR) validation investigate effects on roots. The findings revealed that inhibited development, resulting reduced biomass, total length, surface area, volume, average diameter, tip count. Antioxidant enzyme activities (peroxidase, superoxide dismutase, ascorbate peroxidase, catalase activity) soluble protein content increased with rising toxicity, whereas malondialdehyde initially then declined. Additionally, stress (1439.25%) decreased boron (B, 50.64%), magnesium (Mg, 42.04%), calcium (Ca, 46.02%), manganese (Mn, 86.75%), iron (Fe, 69.92%) levels RNA sequencing (RNA-seq) analysis identified 3855 differentially expressed genes (DEGs) between 0 mmol/L (control) 4 (Al toxicity) concentrations, 1457 up-regulated 2398 down-regulated, indicating a complex molecular regulatory response. qPCR results further validated these findings. elucidates mechanisms stress, providing insights into pathways involved. offer valuable reference points for breeding Al-resistant varieties. this provide important genetic tools technical support screening highly resistant varieties pomelo. On one hand, by detecting key indexes (such as antioxidant activity nutrient absorption capacity) pomelo, excellent anti-Al characteristics can be selected. other study, such TFM1 ALERTFA0, used develop markers, assisted marker breeding, or transgenic accelerate process strains.

Nickel (Ni) toxicity can disorder plant growth and development, while silicon (Si) is important element in ameliorating heavy metal stress. This study investigated the effect of exogenous application Si (2 mM) on cabbage plants exposed to Ni (0.5 mM 1 mM). The impacts root morphology, enzymatic activities, proline glycine betaine (GB) accumulation, reactive oxygen species (ROS), other physiological parameters grown under stress were observed. Exogenous mitigated irreversible damage caused by improving enhancing regulating osmoprotectants (proline betaine), modulating ROC (O2- H2O2), supporting overall physiology. Furthermore, reduced content 67% 72% roots leaves, respectively, improved nutrients (Si, N, P, K) upregulation reducing oxidative findings suggest that foliar 2 enhance regulate nutrient uptake, play a crucial role accumulation. primarily attributed its contribution strengthening defense mechanisms against osmoregulation, thereby alleviating Ni-induced promoting growth.
