Reproduction in the animal kingdom has historically been sexual. Cloning the sheep Dolly in 1997 moved us closer to the possibility of duplicating other animals or humans asexually, but the practice ...

CORVALLIS, Ore., Jan. 3 (UPI) -- A plant preserved in 100 million-year-old amber has revealed the oldest evidence of sexual reproduction in a flowering plant, U.S. and European researchers say.

Researchers have identified a genetic sequence that is essential for plant reproduction. As this region is found in all plant species, it is expected to contribute to future crossbreeding initiatives ...

Scientists have discovered a sexual reproduction process in microalgae that helps them better understand algae and plant evolution. Their discovery could lead to new industrial applications for ...

Two groups of plant molecular biologists have long studied how pollen tubes and pistils, the male and female parts of flowers, communicate to achieve fertilization in plants. Now they report that they ...

Self-incompatibility (SI) is a sophisticated reproductive strategy that prevents self-fertilisation and maintains genetic variability in flowering plants. This mechanism involves highly specific ...

American Journal of Botany, Vol. 96, No. 5 (May, 2009), pp. 904-911 (8 pages) According to life-history theory, reproductive investments involve costs in terms of growth, future fecundity, and/or ...
