• Here, a member of the rice Aux/IAA family genes, OsIAA11 (LOC_Os03g43400), was isolated from a rice mutant defective in lateral root development
• The gain-of-function mutation in OsIAA11 strictly blocks the initiation of lateral root primordia, but it does not affect crown root development
• The expression of OsIAA11 is defined in root tips, lateral root caps, steles, and lateral root primordia
• Taken together, the results indicate that the gain-of-function mutation in OsIAA11 caused the inhibition of lateral root development in rice
• A gain-of-function mutation in OsIAA11 affects lateral root development in rice
• The auxin reporter DR5-GUS (beta-glucuronidase) was expressed at lower levels in the mutant than in wild-type, indicating that OsIAA11 is involved in auxin signaling in root caps
• The transcript abundance of both OsPIN1b and OsPIN10a was diminished in root tips of the Osiaa11 mutant
• Rice Inositol Polyphosphate Kinase (OsIPK2) Directly Interacts with OsIAA11 to Regulate Lateral Root Formation.
• Furthermore, expressing additional OsIPK2 or its N-terminal amino acid sequence enhanced the accumulation of OsIAA11 protein in transgenic plants, which in turn caused defects in lateral root formation and auxin response

• OsCYP2~OsCyp2-P~LRT2, OsIAA11, Peptidyl-prolyl isomerization targets rice Aux/IAAs for proteasomal degradation during auxin signalling., Here we show that peptidyl-prolyl isomerization of rice OsIAA11 catalysed by LATERAL ROOTLESS2 (LRT2), a cyclophilin-type peptidyl-prolyl cis/trans isomerase, directly regulates the stability of OsIAA11
• OsCYP2~OsCyp2-P~LRT2, OsIAA11, Peptidyl-prolyl isomerization targets rice Aux/IAAs for proteasomal degradation during auxin signalling., NMR spectroscopy reveals that LRT2 efficiently catalyses the cis/trans isomerization of OsIAA11
• OsCYP2~OsCyp2-P~LRT2, OsIAA11, Peptidyl-prolyl isomerization targets rice Aux/IAAs for proteasomal degradation during auxin signalling., The lrt2 mutation reduces OsTIR1-OsIAA11 interaction and consequently causes the accumulation of a higher level of OsIAA11 protein
• OsCYP2~OsCyp2-P~LRT2, OsIAA11, Peptidyl-prolyl isomerization targets rice Aux/IAAs for proteasomal degradation during auxin signalling., Moreover, knockdown of the OsIAA11 expression partially rescues the lrt2 mutant phenotype in lateral root development
• OsIAA11, OsIPK2~IPK2~IP6K, Rice Inositol Polyphosphate Kinase OsIPK2 Directly Interacts with OsIAA11 to Regulate Lateral Root Formation., Rice Inositol Polyphosphate Kinase (OsIPK2) Directly Interacts with OsIAA11 to Regulate Lateral Root Formation.
• OsIAA11, OsIPK2~IPK2~IP6K, Rice Inositol Polyphosphate Kinase OsIPK2 Directly Interacts with OsIAA11 to Regulate Lateral Root Formation., Here, we show that OsIPK2, a rice (Oryza sativa) inositol polyphosphate kinase, directly interacts with an Aux/IAA protein OsIAA11 to repress its degradation
• OsIAA11, OsIPK2~IPK2~IP6K, Rice Inositol Polyphosphate Kinase OsIPK2 Directly Interacts with OsIAA11 to Regulate Lateral Root Formation., Furthermore, expressing additional OsIPK2 or its N-terminal amino acid sequence enhanced the accumulation of OsIAA11 protein in transgenic plants, which in turn caused defects in lateral root formation and auxin response
