The development of the radicle at the basal portion of rice rygotic embryos was studied. Median sagittal sections and transverse sections indicated that a radicle tip arose at the ventral side of the...
Ultrastructure of Antipodal Cells of Rice (Oryza sativa) before Anthesis with Special Reference to Concentric Configuration of Endoplasmic Reticula
Antipodal cell Concentric configuration Endoplasmic reticulum Lobed nucleus Oryza sativa
2009/7/23
Before anthesis, rice antipodal cells are located between nucellar cells and a central cell, and have a large-sized lobed nucleus and many cell-wall ingrowths abutting the nucellar cells. An outstandi...
