• Information
  • Symbol: STR2
  • MSU: LOC_Os07g09384
  • RAPdb: Os07g0191600
• Publication
  • The half-size ABC transporters STR1 and STR2 are indispensable for mycorrhizal arbuscule formation in rice, 2012, Plant J.
• Genbank accession number
  • JN608806
• Key message
  • Mutation of either of the Oryza sativa (rice) ABCG transporters blocked arbuscule growth of different AM fungi at a small and stunted stage, recapitulating the phenotype of Medicago truncatula stunted arbuscule 1 and 2 (str1 and str2) mutants that are deficient in homologous ABCG genes
  • Strigolactones have previously been hypothesized to operate as intracellular hyphal branching signals and possible substrates of STR1 and STR2
  • However, full arbuscule development in the strigolactone biosynthesis mutants d10 and d17 suggested strigolactones to be unlikely substrates of STR1/STR2
  • The half-size ABC transporters STR1 and STR2 are indispensable for mycorrhizal arbuscule formation in rice
  • Analogous to STR1 and STR2, at the root cortex level, the antiSTR1 transcript is specifically detected in arbusculated cells, suggesting unexpected modes of STR1 regulation in rice
