The environmental conditions play a crucial role in determining crop yield, which is essential for ensuring food and nutritional security. However, rapid climate change is exacerbating global environmental stress, leading to severe biotic pressures on crops. Therefore, enhancing crop resilience to pathogens has become one of the most pressing challenges for humanity.

OsICS1 but not OsICS-L is directly upregulated by OsWRKY6. Rice (Oryza sativa) is a staple crop for about half of the global population and is particularly important in the diets of people living in Asia, Latin America, and Africa.

During this process, signaling components are modulated by central regulators of various signal transduction pathways. Protein phosphorylation by kinases is one of the most important events transmitting signals downstream, via the posttranslational modification of signaling components.
