Abstract excerpt
The development of embryo sacs, a process regulated by an array of genes, significantly impacts seed setting rate and yield production in rice (Oryza sativa L.). The establishment of the single archesporial cell and single functional megaspore are crucial events during embryo sac development. Nevertheless, the molecular mechanisms controlling the number of archesporial cells and functional megaspore number remain...
