The study was published in Cell on Aug. 18. Seed production by fertilization is essential for plant reproduction and seed crop yield. As early as 1904, botanists observed the interesting phenomenon of ...

(A) Pollen grains generated from the stamen pollinate at the tip of the pistil. Pollen tubes grow inside the pistil towards the ovule located in the placenta. (B) The pollen tubes are guided to the ...

Scientists from Nagoya University, Yokohama City University and Chubu University have developed a system which enables the live imaging of the formation of the female gamete in plants. In flowering ...

New research challenges the idea that self-fertilization is an evolutionary dead end and points to a more complex story.
