Genes essential for female gametogenesis, fertilization, and seed development are present in the embryo sac transcriptome datasets. (a) Chromosomal locations of 35 essential genes. Five genes that are described in the current work are shown in blue. Description of the mutants and corresponding references are given in Additional data file 5. (b) Five genes and the locations of corresponding mutant alleles described in this work. Exons are shaded in orange. The genes were named after the following Goddesses: KERRIDWIN, the Welsh triple Goddess of trinity known for nurturing children; OMISHA, Indian Goddess of birth and death; FREYA, the Norse Goddess of fertility; and ILITHYIA, the Greek Goddess of childbirth. HOG1, HOMOLOGY DEPENDENT GENE SILENCING 1; LB and RB, left and right borders of the T-DNA. (c) Mutants were identified based on infertile ovules (ken-1) or seed abortion (hog1-6, oma-1, fey-1, and ila-1). The arrows identify the defective ovules. Scale bar: 100 μm in panel c.
