• Information
  • Symbol: OsMsr9,OsFBX257
  • MSU: LOC_Os07g37400
  • RAPdb: Os07g0561300
• Publication
  • OsMsr9, a novel putative rice F-box containing protein, confers enhanced salt tolerance in transgenic rice and Arabidopsis, 2014, Molecular Breeding.
  • Stress-induced F-Box protein-coding gene OsFBX257 modulates drought stress adaptations and ABA responses in rice., 2022, Plant Cell Environ.
• Genbank accession number
  • EU276058
• Key message
  • Overexpression of OsMsr9 in Arabidopsis and rice showed enhanced salt stress tolerance displaying increased shoot and root elongation, higher survival rates in transgenic plants compared with wild type
  • In a previous study, it has been shown that OsMsr9 was induced by cold, drought and heat stresses
  • Here, we report that OsMsr9 plays roles in salt tolerance in plants
  • Quantitative real-time PCR (qPCR) analysis revealed that OsMsr9 was also rapidly and strongly induced by salt stress
  • OsMsr9 might act as a positive regulator of plant salt tolerance with reinforced expression of stress-related genes, such as RD29A, DREB2A and RAB18 in transgenic plants under salt conditions
  • These results indicate that OsMsr9 could be a useful gene in developing transgenic crops with enhanced salt tolerance
  • OsFBX257 expression level modulates root architecture and drought stress tolerance in rice
  • OsFBX257 knockdown (OsFBX257(KD) ) lines show reduced total root length and depth, crown root number, panicle size and survival under stress
  • Stress-induced F-Box protein-coding gene OsFBX257 modulates drought stress adaptations and ABA responses in rice.
  • OsFBX257 is a promising breeding target for alleviating drought stress-induced damage in rice
  • OsFBX257 is co-expressed in a network involving protein kinases and phosphatases
  • We show that OsFBX257 can bind the kinases OsCDPK1 and OsSAPK2, and that its phosphorylation can be reversed by phosphatase OsPP2C08
