• Information
  • Symbol: OsAt10
  • MSU: LOC_Os06g39390
  • RAPdb: Os06g0594600
• Publication
  • Overexpression of a BAHD acyltransferase, OsAt10, alters rice cell wall hydroxycinnamic acid content and saccharification, 2013, Plant Physiol.
  • Overexpression of a rice BAHD acyltransferase gene in switchgrass Panicum virgatum L. enhances saccharification., 2018, BMC Biotechnol.
• Genbank accession number
  • CT836223
• Key message
  • An activation-tagged line, OsAT10-D1, shows a 60% reduction in matrix polysaccharide-bound FA and an approximately 300% increase in p-CA in young leaf tissue but no discernible phenotypic alterations in vegetative development, lignin content, or lignin composition
  • Biomass from OsAT10-D1 exhibits a 20% to 40% increase in saccharification yield depending on the assay
  • Thus, OsAt10 is an attractive target for improving grass cell wall quality for fuel and animal feed
  • Overexpression of a BAHD acyltransferase, OsAt10, alters rice cell wall hydroxycinnamic acid content and saccharification
  • Here we show that overexpression of the rice OsAT10 gene in switchgrass decreased the levels of cell wall-bound ferulic acid (FA) in green leaf tissues and to a lesser extent in senesced tissues, and significantly increased levels of cell wall-bound p-coumaric acid (p-CA) in green leaves but decreased its level in senesced tissues of the T0 plants under greenhouse conditions
