• Publication
  • Expression profiling of starch metabolism-related plastidic translocator genes in rice, 2006, Planta.
  • Analysis of the rice ADPglucose transporter OsBT1 indicates the presence of regulatory processes in the amyloplast stroma that control ADPglucose flux into starch, 2016, Plant Physiol.
  • OsBT1 encodes an ADP-glucose transporter involved in starch synthesis and compound granule formation in rice endosperm., 2017, Sci Rep.
• Genbank accession number
  • NM_001052765
• Key message
  • The osbt1 mutant showed a white-core endosperm and a significantly lower grain weight than the wild-type
  • The formation and development of compound starch granules in osbt1 was obviously defective: the amyloplast was disintegrated at early developmental stages and the starch granules were disperse and not compound in the endosperm cells in the centre region of osbt1 seeds
  • OsBT1 encodes an ADP-glucose transporter involved in starch synthesis and compound granule formation in rice endosperm.
  • Furthermore, the expression of starch synthesis related genes was also altered in the osbt1 mutant
  • These findings indicate that OsBT1 plays an important role in starch synthesis and the formation of compound starch granules
  • Map-based cloning of OsBT1 indicated that it encodes a putatively ADP-glucose transporter
