The egg cell is preferentially fertilized in Arabidopsis double fertilization. [PDF]
J Integr Plant Biol, 2022 ABSTRACTIn flowering plants (angiosperms), fertilization of the egg cell by one sperm cell produces an embryo, whereas fusion of a second sperm cell with the central cell generates the endosperm. In most angiosperms like Arabidopsis, a pollen grain contains two isomorphic sperm cells required for this double fertilization process.

Exploring potential strategies for haploid induction based on double fertilization in plants. [PDF]
Plant Biotechnol JHaploid induction (HI), an indispensable procedure in doubled haploid breeding, has attracted increasing attention in crop genetic improvement due to its ability to rapidly fix desirable traits in a homozygous state, thereby shortening the breeding cycle.

Three Cell Fusions during Double Fertilization. [PDF]
Cell, 2015 Fertilization of both egg and central cell is a major distinguishing feature of flowering plants. Now, Maruyama et al. report a third cell fusion event between the persistent synergid and the fertilized central cell shortly after double fertilization in Arabidopsis. This causes rapid dilution of pollen tube attractant(s), preventing polytubey.

The WASP-Arp2/3 complex signal cascade is involved in actin-dependent sperm nuclei migration during double fertilization in tobacco and maize. [PDF]
Sci Rep, 2017 Sperm nuclear migration during fertilization in Arabidopsis and rice has recently been found to be actin-dependent, but the driving force behind this actin cytoskeleton-dependent motion is unclear. Here, we confirmed that the actin-dependent sperm nuclei

One-time double-layer placement of controlled-release urea enhances wheat yield, nitrogen use efficiency and mitigates N2O emissions [PDF]
Frontiers in Plant ScienceSimultaneously enhancing the crop yield and reducing nitrous oxide (N2O) emissions presents a critical challenge in sustainable agriculture. The application of nitrogen (N) fertilizer is a key strategy to enhance crop yield.

Frontiers in Plant Science, 2021 Asparagaceae’s large embryo sacs display a central cell nucleus polarized toward the chalaza, which means the sperm nucleus that fuses with it during double fertilization migrates an atypical long distance before karyogamy.
