NUANCES. “The transcriptional activation of male and female genomes in the zygote is critical for establishing apical–basal cell polarity over a long period of time before the first division. Our data suggest that unlike egg cell functioning in animals such as hamster, in Arabidopsis, a single spike of [Ca2+]cyt at fertilization with a duration that is much shorter than that observed during maize in vitro fertilization, might be sufficient for blocking polyspermy and initiation of the developmental programme.”
