Item Zinc homeostasis and carbon sequestration as influenced by biofertilizers and CO2 enrichment in rice (Oryza sativa L.)(Department of plant pathology, college of agriculture ,Vellayani, 2023-07-21) Amrutha, E A.; Manju, R VThe study entitled "Zinc homeostasis and carbon sequestration as influenced by biofertilizers and CO2 enrichment in rice (Oryza sativa L.)" was undertaken with the objectives of assessing the impact of biofertilizers on Zn uptake, translocation and soil carbon sequestration and the mechanism of Zn transport as influenced by CO2 enrichment. The first experiment was conducted to study the influence of biofertilizers on Zn uptake, translocation, and carbon sequestration at IFSRS, Karamana. The experiment was laid out in RBD with eleven treatments and three replications. The treatments comprised of T1: PoP, KAU + Azolla, T2: PoP, KAU + AMF, T3: PoP, KAU + PGPR Mix I, T4: PoP, KAU + KSB, T5: PoP, KAU + PSB, T6: T1 + AMF, T7: T1 + PGPR Mix I, T8: T1 + KSB, T9: T1 + PSB, T10: Control and T11: PoP+ Zinc sulphate spray. The gene expression analysis revealed the down regulation of OsZIP4 genes under elevated CO2 compared to ambient CO2. Biofertilizer induced overexpression of OsZIP 4 genes is found to play significant role in improving Zn translocation. The study results could be helpful to formulate climate smart agricultural practices strategies to address the wide spread problem of limited availability of Zn among the population
