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 ...

In the flowering plant world, reproduction means an intricate succession of events. It begins when a pollen grain that carries the sperm cells lands on the top of the pistil, the female reproductive ...

Question: We have a crape myrtle tree in our southwest back yard. It gets plenty of water, and I fertilized it last month with some Miracle-Gro flowering fertilizer. At the time, there were some ...

Pollen tube guidance towards the ovule is an important step for fertilization in flowering plants. In order for this to happen, a pollen tube attractant peptide LURE guides the pollen tube precisely ...

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 peptide, named NON-DEFENSIN PEPTIDE ATTRACTANT 1 (NPA1), represents the first non-defensin-type attractant identified in dicots and expands the known diversity of fertilization cues in flowering ...

Today, more than a century after a German-Polish botanist first described the process of fertilization in flowering plants, scientists have identified an elusive molecular signal critical to that ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 117, No. 51 (December 22, 2020), pp. 32757-32763 (7 pages) After eukaryotic fertilization, gamete nuclei migrate ...

Fertilization in flowering plants is dependent on a protein that is secreted by the egg cell and activates incoming sperm. Stefanie Sprunck at the University of Regensburg in Germany and her ...
