• Publication
  • Adventitious root formation in rice requires OsGNOM1 and is mediated by the OsPINs family, 2009, Cell Res.
  • Over-expression of OsPIN2 leads to increased tiller numbers, angle and shorter plant height through suppression of OsLAZY1, 2012, Plant Biotechnol J.
  • Overexpressing OsPIN2 enhances aluminium internalization by elevating vesicular trafficking in rice root apex., 2015, J Exp Bot.
• Genbank accession number
  • AK101191
• Key message
  • The data suggest that OsPIN2 has a distinct auxin-dependent regulation pathway together with OsPIN1b and OsTAC1 controlling rice shoot architecture
  • The expression patterns of the auxin reporter DR5::GUS and quantification of auxin distribution showed that OsPIN2 over-expression increased auxin transport from the shoot to the root-shoot junction, resulting in a non-tissue-specific accumulation of more free auxin at the root-shoot junction relative to WT
  • Over-expression of OsPIN2 enhanced auxin transport from shoots to roots, but did not alter the polar auxin pattern in the roots
  • OsPIN2-over-expressing plants had suppressed the expression of a gravitropism-related gene OsLazy1 in the shoots, but unaltered expression of OsPIN1b and OsTAC1, which were reported as tiller angle controllers in rice
  • Over-expression of OsPIN2 leads to increased tiller numbers, angle and shorter plant height through suppression of OsLAZY1
  • Altering OsPIN2 expression by genetic transformation can be directly used for modifying rice architecture
  • Overexpressing OsPIN2 enhances aluminium internalization by elevating vesicular trafficking in rice root apex.
  • In this study, it was found that the rice OsPIN2 overexpression line (OX1) had significantly reduced Al content in its cell wall and increased Al concentration in cell sap only in rice root tips relative to the wild-type (WT)
  • Taken together, the data indicate that endocytic vesicular trafficking might contribute to Al internalization, and that overexpressing OsPIN2 enhances rice Al tolerance via elevated endocytic vesicular trafficking and Al internalization
  • Overexpressing OsPIN2 enhances aluminium internalization by elevating vesicular trafficking in rice root apex
• Connection

  • OsPIN2, TAC1, Over-expression of OsPIN2 leads to increased tiller numbers, angle and shorter plant height through suppression of OsLAZY1, The data suggest that OsPIN2 has a distinct auxin-dependent regulation pathway together with OsPIN1b and OsTAC1 controlling rice shoot architecture
  • OsPIN2, VLN2, VLN2 Regulates Plant Architecture by Affecting Microfilament Dynamics and Polar Auxin Transport in Rice, Together, our results demonstrate that VLN2 plays an important role in regulating plant architecture by modulating MF dynamics, recycling of PIN2, and polar auxin transport
