LOC_Os11g32100 is a rice (*Oryza sativa*) gene encoding a protein implicated in stress response and developmental regulation. It belongs to the plant-specific DUF1645 protein family, characterized by a conserved domain of unknown function. Studies suggest its involvement in abiotic stress tolerance, particularly drought and salinity, through modulation of cellular osmoregulation and antioxidant pathways. The gene is expressed in roots, shoots, and reproductive tissues, with expression upregulated under stress conditions.
Recombinant LOC_Os11g32100 protein has been produced in *E. coli* or yeast systems for functional studies. Purification typically involves affinity tags (e.g., His-tag) due to its low molecular weight (~20 kDa) and soluble expression under optimized conditions. Structural analyses predict an α-helix-rich fold, though its precise molecular mechanism remains unclear. Interaction studies indicate potential binding to signaling molecules like calcium ions or kinases, suggesting roles in stress signal transduction.
Research highlights its importance in rice breeding programs aiming to enhance climate resilience. Overexpression lines exhibit improved root architecture and water retention under drought, while knockout mutants show heightened sensitivity to oxidative stress. However, its pleiotropic effects on growth require further investigation. Current work focuses on elucidating its interactome and downstream targets using recombinant protein-based assays. These efforts aim to bridge the gap between genetic data and actionable agronomic traits for sustainable rice cultivation.
