  • A null mutation of ROS1a for DNA demethylation in rice is not transmittable to progeny, 2012, Plant J.
• Genbank accession number
  • CT834898
• Key message
  • These T(0) plants exhibited no overt morphological phenotypes during the vegetative phase, and GUS staining showed ROS1a expression in pollen, unfertilized ovules and meristematic cells
  • Even in the presence of the wild-type paternal ROS1a allele, the maternal ros1a-GUS1 allele caused failure of early-stage endosperm development, resulting in incomplete embryo development, with embryogenesis producing irregular but viable embryos that failed to complete seed dormancy, implying non-equivalent maternal and paternal contribution of ROS1a in endosperm development
