Genbank accession number

• SCF OsFBK1 E3 ligase mediates jasmonic acid induced turn-over of OsATL53 and OsCCR14 to regulate rice anther and root lignification.
• SCF OsFBK1 mediates turn-over of OsATL53 in cytoplasm and nucleus, while of OsCCR14 in the nucleus as validated by cell-free degradation assays
• Currently, we have identified OsATL53, a member of ATL family of RING-H2 proteins interacting with OsCCR14 in cytoplasm
• Biochemically, OsATL53 decreases enzymatic activity of OsCCR14 and sequesters it in the cytoplasm thereby regulating the lignification process
• Knock-down rice transgenics of OsATL53 display increased lignin deposition in the anthers and roots vis-a-vis wild-type, while those of OsCCR14 have decreased lignin content

• OsCCR14, OsFBK1, SCF OsFBK1 E3 ligase mediates jasmonic acid induced turn-over of OsATL53 and OsCCR14 to regulate rice anther and root lignification., SCF OsFBK1 E3 ligase mediates jasmonic acid induced turn-over of OsATL53 and OsCCR14 to regulate rice anther and root lignification.
• OsCCR14, OsFBK1, SCF OsFBK1 E3 ligase mediates jasmonic acid induced turn-over of OsATL53 and OsCCR14 to regulate rice anther and root lignification., We have shown earlier the F-box protein, OsFBK1, mediating turn-over of a cinnamoyl CoA-reductase, OsCCR14, to regulate rice anther and root lignification
• OsCCR14, OsFBK1, SCF OsFBK1 E3 ligase mediates jasmonic acid induced turn-over of OsATL53 and OsCCR14 to regulate rice anther and root lignification., SCF OsFBK1 mediates turn-over of OsATL53 in cytoplasm and nucleus, while of OsCCR14 in the nucleus as validated by cell-free degradation assays
• OsCCR14, OsFBK1, SCF OsFBK1 E3 ligase mediates jasmonic acid induced turn-over of OsATL53 and OsCCR14 to regulate rice anther and root lignification., These data show OsATL53 affects activity of OsCCR14, and their JA induced degradation by SCF OsFBK1 regulates lignification of rice anthers and roots
