Discussion

WOX8/9 genes are axis patterning genes, which WRKY2 is a direct transcriptional regulator. This regulation pathway was known for the regulation of asymmetric embryo lineage development which occurs after the division of the zygote. This paper states that it also regulates the polarity of the zygote itself.

The expression “transient symmetric state” is used in this paper to note the finding that the polarized state of the egg cell is not contiguous in the developmental stage, and re-polarization of the zygote requires WRKY2.

WOX8 and WOX9 genes are functional homologues. It is not shown in the paper how WOX8 expression is confined to the basal daughter.
