• Information
  • Symbol: STR1
  • MSU: LOC_Os09g23640
  • RAPdb: Os09g0401100
• Publication
  • The half-size ABC transporters STR1 and STR2 are indispensable for mycorrhizal arbuscule formation in rice, 2012, Plant J.
• Genbank accession number
  • JN608807
• 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
  • 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
  • Malnutrition of the fungus underlying limited arbuscular growth was excluded by the absence of complementation of the str1 phenotype by wild-type nurse plants
  • 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

  • OsSTRL2, STR1, An atypical strictosidine synthase, OsSTRL2, plays key roles in anther development and pollen wall formation in rice., Comparative protein sequence analysis indicated that OsSTRL2 lacked the key catalytic residue found in a typical STR (STR1), although it possessed conserved β-propellers and α-helices formed the basic structure of STR1
