Gene Details:

• MSU gene ID: LOC_Os03g21040
• RAPdb gene ID: Os03g0327600
• Gene Symbol: Osr40c1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Rice lectin protein Osr40c1 imparts drought tolerance by modulating OsSAM2, OsSAP8 and chromatin-associated proteins.
• In this study, it has been depicted that expression of Osr40c1 gene correlates with the drought tolerance potential of various rice cultivars.
• Transgenic rice plants overexpressing Osr40c1 were significantly more tolerant to drought stress over the wild-type plants.
• Silencing of each of these protein partners led to drought sensitivity in the otherwise tolerant Osr40c1 expressing transgenic tobacco lines indicating that these partners were crucial for the Osr40c1-mediated drought tolerance in planta.
• Moreover, the association of Osr40c1 with these partners occurred specifically under drought stress forming a multi-protein complex.
• Together, the present investigation delineated the novel role of Osr40c1 protein in imparting drought tolerance by regulating OsMNB1B, OsSAM2, and OsH4 proteins, which presumably enables OsSAP8 to induce downstream gene expression.
