The egg cell is preferentially fertilized in Arabidopsis double fertilization [PDF]
Journal of Integrative Plant Biology, 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.

Double fertilization: a personal view
Sexual Plant Reproduction, 1998This year marks the 100th anniversary of the discovery of double fertilization by Nawaschin in St. Petersburg, Russia and, independently, Guignard in France. This discovery came at the end of a period of controversy about fertilization in angiosperms and ushered in a new period of intense research.

Double fertilization in flowering plants: 1898–2008
Cytology and Genetics, 2008 The present article gives a brief survey of results of studies in the area of plant embryology directly associated with the discovery made by S.G. Navashin in 1898 of double fertilization in vivo and in vitro. These studies utilized methods of electronic and fluorescence microscopy, cytophotometry, and cultures of isolated ovules, sperm, and the embryo

Developmental and evolutionary hypotheses for the origin of double fertilization and endosperm
Comptes Rendus De L'Académie Des Sciences Série 3, Sciences De La Vie, 2001The discovery of a second fertilization event that initiates endosperm in flowering plants, just over a century ago, stimulated intense interest in the evolutionary history and homology of endosperm, the genetically biparental embryo-nourishing tissue that is found only in angiosperms.

Double fertilization on the move
Current Opinion in Plant Biology, 2012Double fertilization is a flowering plant mechanism whereby two immotile sperm cells fertilize two different female gametes. One of the two sperm cells fertilizes the egg cell to produce the embryo and the other fertilizes the central cell to produce the endosperm.

Double fertilization – caught in the act
Trends in Plant Science, 2008In flowering plants, fertilization is unique because it involves two pairs of male and female gametes, a process known as double fertilization. Here, we provide an overview of the field and a detailed review of the outstanding recent advances, including in vivo imaging of double fertilization and the identification of a signaling pathway controlling ...

Male–Female Crosstalk during Pollen Germination, Tube Growth and Guidance, and Double Fertilization
Molecular Plant, 2013 Sperm cells of flowering plants are non-motile and thus require transportation to the egg apparatus via the pollen tube to execute double fertilization.

Double fertilization in vitro and the origin of human chimerism
Fertility and Sterility, 1990A human embryo consisting of two cells, each containing two pronuclei, was found in the IVF laboratory. The most likely explanation for this phenomenon is a parthenogenetic activation of an oocyte leading to immediate cleavage and followed by double fertilization. Human chimerism may originate in this way.

Fertility of doubled monoploids ofSolanum phureja
American Potato Journal, 1992Thirteen anther-derived doubled monoploids and their heterozygous diploid anther donor were evaluated in the greenhouse for flowering, fruit set, seed set and pollen fertility. Doubled monoploids varied for number of days to flower, duration of flowering, abundance of flowers and general flower quality. Fruit set on the doubled monoploids in controlled
