Polyspermy Block in the Central Cell During Double Fertilization of Arabidopsis thaliana [PDF]
Frontiers in Plant Science, 2021 During double fertilization in angiosperms, two male gametes (sperm cells), are released from a pollen tube into the receptive region between two female gametes; the egg cell and the central cell of the ovule.

Identification and Analysis of Genes Involved in Double Fertilization in Rice [PDF]
International Journal of Molecular Sciences, 2021 Double fertilization is a key determinant of grain yield, and the failure of fertilization during hybridization is one important reason for reproductive isolation.

Transcriptional repression specifies the central cell for double fertilization [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Double fertilization is a key innovation of flowering plants. The central cell is the second female gamete, and its fertilization gives rise to the endosperm, the nurse of a seed. However, how this cell is specified and evolved in angiosperm

The beginning of a seed: regulatory mechanisms of double fertilization [PDF]
Frontiers in Plant Science, 2014 The launch of seed development in flowering plants (angiosperms) is initiated by the process of double fertilization: two male gametes (sperm cells) fuse with two female gametes (egg and central cell) to form the precursor cells of the two major seed ...

ECS1 and ECS2 suppress polyspermy and the formation of haploid plants by promoting double fertilization [PDF]
eLife, 2023 The current pace of crop plant optimization is insufficient to meet future demands and there is an urgent need for novel breeding strategies. It was previously shown that plants tolerate the generation of triparental polyspermy-derived plants and that ...

Double fertilization in Helianthus
Acta Societatis Botanicorum Poloniae, 2015 After controlled pollination of Helianthus annuus L. florets, the whole course of fertilization is described and documented on 24 microphotos. The timing of events is evaluated.

Live imaging of calcium spikes during double fertilization in Arabidopsis [PDF]
Nature Communications, 2014 Ca2+ waves and oscillation are key signalling elements during the fertilization process of animals, and are involved, for example, in egg activation. In the unique double fertilization process in flowering plants, both the egg cell and the neighbouring ...

Abortion occurs during double fertilization and ovule development in Paeonia ludlowii. [PDF]
J Plant Res, 2022 Paeonia ludlowii (Stern & Taylor) D.Y.Hong, an endangered species, is indigenous to Tibet, China and propagated only by seed under natural conditions. Its natural reproduction is constrained by low fecundity.

Behavior of Male Gamete Fusogen GCS1/HAP2 and the Regulation in Arabidopsis Double Fertilization [PDF]
Biomolecules, 2023 In the sexual reproduction of flowering plants, two independent fertilization events occur almost simultaneously: two identical sperm cells fuse with either the egg cell or the central cell, resulting in embryo and endosperm development to produce a seed.

Reactive Oxygen Species as Mediators of Gametophyte Development and Double Fertilization in Flowering Plants. [PDF]
Front Plant Sci, 2020 Reactive oxygen species (ROS) are toxic by-products of aerobic metabolism. In plants, they also function as important signaling molecules that regulate biotic and abiotic stress responses as well as plant growth and development.
