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. Therefore, fertilization has a very important role in the production of high-yield and well-quality hybrid of rice.

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 ...

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.

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.

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 remains unknown.

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.

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.

Fruit growth and development in apple: a molecular, genomics and epigenetics perspective
Frontiers in Plant Science, 2023 Fruit growth and development are physiological processes controlled by several internal and external factors. This complex regulatory mechanism comprises a series of events occurring in a chronological order over a growing season.

Removal of the endoplasma membrane upon sperm cell activation after pollen tube discharge
Frontiers in Plant Science, 2023 In pollen and pollen tubes, immotile sperm cells are enclosed by an inner vegetative plasma membrane (IVPM), a single endomembrane originating from the vegetative-cell plasma membrane.
