Abstract
Rice (Oryza sativa) is a crucial crop, achieving high yield concurrent pathogen resistance remains a challenge. Transcription factors play roles in growth and abiotic tolerance. However, rice phytochrome-interacting factor-like 1 (OsPIL1) in pathogen resistance and agronomic traits remains unexplored. We generated OsPIL1 overexpressing (OsPIL1 OE) rice lines and evaluated their impact on growth, grain development, and resistance to Magnaporthe oryzae. Multiomics analysis (RNA-seq, metabolomics, and CUT&Tag) and RT-qPCR validated OsPIL1 target genes and key metabolites. In the results, OsPIL1 OE rice lines exhibited robust growth, longer grains, and enhanced resistance to M. oryzae without compromising growth. Integrative multiomics analysis revealed a coordinated regulatory network centered on OsPIL1, explaining these desirable traits. OsPIL1 likely acts as a positive regulator, targeting transcriptional elements or specific genes with direct functions in several biological programs. In particular, a range of key signaling genes (phosphatases, kinases, plant hormone genes, transcription factors), and metabolites (linolenic acid, vitamin E, trigonelline, d-glucose, serotonin, choline, genistein, riboflavin) contributed to enhanced rice growth, grain size, pathogen resistance, or a combination of these traits. These findings highlight OsPIL1's regulatory role in promoting important traits and provide insights into potential strategies for rice breeding.
