Exploring regulatory roles of putrescine-doped zinc oxide nanoentities on ethylene signaling, redox imbalance, and programmed cell death in drought-stressed rice (Oryza sativa L.) seedlings

Exploring regulatory roles of putrescine-doped zinc oxide nanoentities on ethylene signaling, redox imbalance, and programmed cell death in drought-stressed rice (Oryza sativa L.) seedlings

We investigated the synergistic effects of putrescine-doped zinc oxide nanoparticles (PUT-nZnO) on drought-stressed rice seedlings. Our results demonstrate that PUT-nZnO enhances drought stress (DS) tolerance by improving redox balance, chloroplast integrity, and polyamine (PA) metabolism, offering...
