Gene Details:

• MSU gene ID: LOC_Os04g38870
• RAPdb gene ID: Os04g0462500
• Gene Symbol: GF14b OsGF14b
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsGF14b Positively Regulates Panicle Blast Resistance, but Negatively Regulates Leaf Blast Resistance in Rice.
• Previous research demonstrated that OsGF14b plays different roles in panicle and leaf blast resistance.
• Furthermore, mutation and overexpression of OsGF14b affected the expression of stress-related genes under normal growth conditions and/or drought stress conditions.
• Involvement of OsGF14b Adaptation in the Drought Resistance of Rice Plants.
• In this study, we researched the function of OsGF14b in drought resistance in rice.
• In comparison with wild type (WT), the OsGF14b mutant exhibited improved resistance to drought and osmotic stress by changing the content of stress-relevant parameters, complementation of the OsGF14b mutant restored the drought sensitivity to WT levels, whereas the OsGF14b-overexpression lines exhibited enhanced sensitivity to drought and osmotic stress.
• We have demonstrated that OsGF14b is involved in the drought resistance of rice plants, partially in an ABA-dependent manner.
• Here, we report that OsGF14b was strongly induced by soil drought stress.
• The OsGF14b mutant plants were hypersensitive to abscisic acid (ABA), while the OsGF14b-overexpression plants showed reduced sensitivity to ABA.
• Rice G protein γ subunit qPE9-1 modulates root elongation for phosphorus uptake by involving 14-3-3 protein OsGF14b and plasma membrane H + -ATPase.
• Moreover, the overexpression of OsGF14b in WYJ8 (carrying the qpe9-1 allele) partially increased primary root length under LP conditions.
• These results suggest that the G protein subunit qPE9-1 in rice plants modulates root elongation for phosphorus uptake by involving the 14-3-3 protein OsGF14b and PM H+ -ATPase, which is required for rice P use.
• The serine acids (Ser258Ser259) residues of OsGF14b play an essential role in BR-mediated responses and plant development.
• qGL3/OsPPKL1 Induces Phosphorylation of 14-3-3 OsGF14b to Inhibit OsBZR1 Function in Brassinosteroid Signaling.
• Genetic and molecular analyses indicated that OsGF14b functions as a negative regulator in BR signaling and represses the transcriptional activation activity of OsBZR1.
• OsGF14b is involved in regulating coarse root and fine root biomass partitioning in response to elevated [CO(2)] in rice.
• Our results indicate that knockout of OsGF14b may improve the response to elevated [CO(2)] in rice by enhancing carbon allocation to coarse roots and to fine lateral roots.
• Similar to OsPLC1, OsGF14b also positively regulates rice salt tolerance, and their interaction can be promoted by NaCl stress.
• Under salt stress, the OsPLC1 protein level in OsGF14b was lower than the corresponding value of WT, whereas overexpression of OsGF14b results in a significant increase of OsPLC1 stability.
• Taken together, we propose that OsGF14b can interact with OsPLC1 and promote its activity and stability, thereby improving rice salt tolerance.
