Flowering plants naturally know when they need to spare or perish their cells. In a new study, an international group of plant biologists has examined the ovules of plant cells by live-imaging to ...

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 ...

Researchers found that attractant peptides released by female tissues initiate rapid depolymerization and repolymerization of actin at the leading edge of the pollen tube tip, steering its direction ...

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 ...

The fitness consequences of self-fertilization are largely determined by how self-pollination occurs. Within-flower self-pollination (autogamy) may be advantageous, since it can provide reproductive ...

AMOR was found to be responsible for activating pollen tubes to lead to fertilization. Moreover, through the collaboration between biologists and chemists, the group has synthesized a disaccharide, ...

Flowering plants naturally know when they need to spare or perish their cells. Scientists have now examined the ovules of plant cells to reveal a novel cell-elimination system based on an unusual cell ...
