• Notably, transgenic rice plants with root-preferential overexpression of OsCCR10 exhibited higher grain yield than NT controls plants under field drought conditions, indicating that lignin biosynthesis mediated by OsCCR10 contributes to drought tolerance
• Transgenic rice plants overexpressing OsCCR10 showed improved drought tolerance at the vegetative stages of growth, as well as higher photosynthetic efficiency, lower water loss rates, and higher lignin content in roots compared to non-transgenic (NT) controls
• In contrast, CRISPR/Cas9-mediated OsCCR10 knock-out mutants exhibited reduced lignin accumulation in roots and less drought tolerance
• The OsCCR10 transcript levels were found to increase in response to abiotic stresses, such as drought, high salinity, and abscisic acid (ABA), and transcripts were detected in roots at all developmental stages
• Subcellular localisation assays revealed that OsCCR10 is a catalytically active enzyme that is localised in the cytoplasm

• OsCCR10, OsNAC5, Transcriptional activation of rice CINNAMOYL-CoA REDUCTASE 10 by OsNAC5, contributes to drought tolerance by modulating lignin accumulation in roots., Here, we report that the rice (Oryza sativa) gene CINNAMOYL-CoA REDUCTASE 10 (OsCCR10) is directly activated by the OsNAC5 transcription factor, which mediates drought tolerance through regulating lignin accumulation
• OsCCR10, OsNAC055, Transcription factor OsNAC055 regulates GA-mediated lignin biosynthesis in rice straw., Further ChIP-qPCR analysis and transient transactivation assays indicated that OsNAC055 directly activates rice lignin biosynthetic genes CINNAMOYL-CoA REDUCTASE 10 (OsCCR10) and CINNAMYL ALCOHOL DEHYDROGENASE 2 (OsCAD2) by binding to their promoters
