Plant development: Suspensors as a battlefield for parental tug-of-war?

Parental contributions to zygotes can influence early embryogenesis and may regulate the distribution of maternal resources to progeny. A new study in Arabidopsis thaliana has demonstrated that signaling components from maternal sporophytic tissues and paternal gametes converge in zygotes to promote...

Description
Summary:Parental contributions to zygotes can influence early embryogenesis and may regulate the distribution of maternal resources to progeny. A new study in Arabidopsis thaliana has demonstrated that signaling components from maternal sporophytic tissues and paternal gametes converge in zygotes to promote elongation of the extraembryonic suspensor, which supports the developing embryo proper.
