  • 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
