• Publication
  • The U-box E3 ubiquitin ligase TUD1 functions with a heterotrimeric G alpha subunit to regulate Brassinosteroid-mediated growth in rice, 2013, PLoS Genet.

• Genbank accession number

• Key message
  • The U-box E3 ubiquitin ligase TUD1 functions with a heterotrimeric G alpha subunit to regulate Brassinosteroid-mediated growth in rice
  • In this study, we report a D1 genetic interactor Taihu Dwarf1 (TUD1) that encodes a functional U-box E3 ubiquitin ligase
  • Histological observations showed that the dwarf phenotype of tud1 is mainly due to decreased cell proliferation and disorganized cell files in aerial organs
  • Genetic, phenotypic, and physiological analyses have shown that tud1 is epistatic to d1 and is less sensitive to BR treatment
  • In the dsg1 mutant (an allelic mutant of tud1), the lengths of the roots, internodes, panicles, and seeds were shorter than that in the wild-type, which was due to defects in cell division and elongation
  • These results demonstrate that DSG1 positively regulates cell division and elongation and may be involved in multiple hormone pathways
  • The dsg1 mutant is less sensitive to brassinosteroid treatment than the wild-type, and DSG1 expression is negatively regulated by brassinosteroids, ethylene, auxin, and salicylic acid

  • D1~RGA1, TUD1~DSG1, The U-box E3 ubiquitin ligase TUD1 functions with a heterotrimeric G alpha subunit to regulate Brassinosteroid-mediated growth in rice, Furthermore, we found that D1 directly interacts with TUD1
  • D1~RGA1, TUD1~DSG1, The U-box E3 ubiquitin ligase TUD1 functions with a heterotrimeric G alpha subunit to regulate Brassinosteroid-mediated growth in rice, Taken together, these results demonstrate that D1 and TUD1 act together to mediate a BR-signaling pathway
