Potential toxic element (PTE) pollution has emerged as a significant environmental and social concern in global agriculture. Chromium (Cr) occurs different oxidation states naturally, among them Cr(VI), which is highly toxic. This study carried out biochemical molecular tests to elucidate the accumulation of total soluble phenolics (TSPs) rice plants exposed Cr(VI) at 2.0, 8.0, 16.0 mg Cr/L, emphasizing interaction between polyamines (PAs) abscisic acid (ABA). The results revealed Cr tissues plants, hindered their growth. exposure increased ABA concentration, with higher levels detected shoots than roots. TSP concentration showed positive relationship supplied concentrations Cr(VI). measured PAs, including spermine (Spm), putrescine (Put), spermidine (Spd), exhibited varied responses stress, only Spm increasing concentrations. Real-time qRT-PCR PAs synthesis-associated genes such OsADC1, OsAIH, OsCPA1, OsCPA4 were significantly up-regulated shoot treated These are associated second pathway Put synthesis, originating from Arg. Almost all activated Met well. Moreover, involved interconversion three species completely exposure. Overall, analysis gene expression data indicate that likely enhance subjected toxicity.
