Flowering seed plants (angiosperms) have evolved unique ways to protect their gametes from pathogen attack and from drying out. The female gametes (egg and central cell) are deeply embedded in the ...

Since the discovery of double fertilization over a century ago, proteins mediating gamete interactions in flowering plants have remained elusive. A lily protein located at the sperm-cell surface that ...

Mark Johnson, associate professor of biology, has joined a consortium of seven other researchers in four European countries to develop the fullest understanding yet of how fertilization evolved in ...

Researchers led by Dr. LI Hongju from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences have revealed that the female gamete in flowering plants controls ...

This depicts double fertilization and termination of the pollen tube attraction. Synergid cells play a key role in attracting pollen tubes. Disclaimer: AAAS and EurekAlert! are not responsible for the ...

The initiation of seed development in angiosperms typically requires double fertilization 1, during which two sperm cells are delivered by a pollen tube to the female gametophyte in the ovule (Fig. 1) ...
