- Key message
- Rice GDP-mannose pyrophosphorylase OsVTC1-1 and OsVTC1-3 play different roles in ascorbic acid synthesis.
- Our work demonstrates an important link between excessive root NH(4) (+) efflux and OsVTC1-3-mediated protein N-glycosylation in rice grown under NH(4) (+) nutrition and identifies OsEIL1 as a direct genetic regulator of OsVTC1-3 expression
- Connection
- OsVTC1-3~OsMPG3, OsVTC1-8, Rice GDP-mannose pyrophosphorylase OsVTC1-1 and OsVTC1-3 play different roles in ascorbic acid synthesis., The rice genome encodes three GMPase homologs OsVTC1-1, OsVTC1-3 and OsVTC1-8, but their roles in AsA synthesis are unclear
- OsVTC1-3~OsMPG3, OsVTC1-8, Rice GDP-mannose pyrophosphorylase OsVTC1-1 and OsVTC1-3 play different roles in ascorbic acid synthesis., The overexpression of OsVTC1-1 or OsVTC1-3 restored the AsA synthesis of vtc1-1 in Arabidopsis, while that of OsVTC1-8 did not, indicating that only OsVTC1-1 and OsVTC1-3 are involved in AsA synthesis in rice
- OsVTC1-3~OsMPG3, OsVTC1-8, Rice GDP-mannose pyrophosphorylase OsVTC1-1 and OsVTC1-3 play different roles in ascorbic acid synthesis., Unlike OsVTC1-1, the expression level of OsVTC1-3 was high in roots and quickly induced by the dark, while the transcription level of OsVTC1-8 did not show obvious changes under constant light or dark treatments
- OsVTC1-3~OsMPG3, OsVTC1-8, Rice GDP-mannose pyrophosphorylase OsVTC1-1 and OsVTC1-3 play different roles in ascorbic acid synthesis., The enzyme activity showed that OsVTC1-1 and OsVTC1-3 had higher GMPase activities than OsVTC1-8 in vitro
- OsEIL1~MHZ6, OsVTC1-3~OsMPG3, OsEIL1 protects rice growth under NH4 + nutrition by regulating OsVTC1-3-dependent N-glycosylation and root NH4 + efflux., OsEIL1 constrains NH(4) (+) efflux by activation of OsVTC1-3, but not OsVTC1-1 or OsVTC1-8
- OsEIL1~MHZ6, OsVTC1-3~OsMPG3, OsEIL1 protects rice growth under NH4 + nutrition by regulating OsVTC1-3-dependent N-glycosylation and root NH4 + efflux., OsEIL1 binds directly to the promoter EIN3-binding site (EBS) of OsVTC1-3 in vitro and in vivo and acts to increase the transcription of OsVTC1-3
- OsEIL1~MHZ6, OsVTC1-3~OsMPG3, OsEIL1 protects rice growth under NH4 + nutrition by regulating OsVTC1-3-dependent N-glycosylation and root NH4 + efflux., Our work demonstrates an important link between excessive root NH(4) (+) efflux and OsVTC1-3-mediated protein N-glycosylation in rice grown under NH(4) (+) nutrition and identifies OsEIL1 as a direct genetic regulator of OsVTC1-3 expression
- OsMPG1~OsVTC1-1, OsVTC1-3~OsMPG3, OsEIL1 protects rice growth under NH4 + nutrition by regulating OsVTC1-3-dependent N-glycosylation and root NH4 + efflux., OsEIL1 constrains NH(4) (+) efflux by activation of OsVTC1-3, but not OsVTC1-1 or OsVTC1-8
- OsVTC1-3~OsMPG3, OsVTC1-8, OsEIL1 protects rice growth under NH4 + nutrition by regulating OsVTC1-3-dependent N-glycosylation and root NH4 + efflux., OsEIL1 constrains NH(4) (+) efflux by activation of OsVTC1-3, but not OsVTC1-1 or OsVTC1-8
- OsMPG1~OsVTC1-1, OsVTC1-3~OsMPG3, OsVTC1-1 Gene Silencing Promotes a Defense Response in Rice and Enhances Resistance to Magnaporthe oryzae., The OsVTC1 gene has three homologs in the rice genome: OsVTC1-1, OsVTC1-3, and OsVTC1-8
