A gradient (red) in the concentration of auxin, a plant hormone, determines that only one of the eight undifferentiated nuclei in a plant's embryo sac will become an egg. (In this image, a large ...

The exchange of ideas and information between vegetation ecology and pollination ecology is relatively restricted, yet both fields have devised methods to detect the structure of species assemblages ...

This video segment adapted from NOVA explains how flowers play a central role in the reproductive cycle of plants. Their striking array of colors, patterns, fragrances, and nectar all require lots of ...

A gradient (red) in the concentration of the plant hormone auxin determines that only one of the eight nuclei in a plant's embryo sac will become an egg. (The blue island in the image is a cell ...

Asteraceae presents one of the most diverse and intricate reproductive systems among flowering plants. The family is typified by its composite inflorescences, which combine both ray and disc florets ...

Sex in the garden is more straightforward for the birds and the bees than it’s for the plants. Reproductive processes vary among flowering plants; for many, there is more than one option. When ...

Plant reproductive complexity increased in two, widely separated pulses likely driven by important evolutionary innovations, including the origin of seeds and flowers, according to a new study. These ...

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 ...

Studying plant vegetative reproduction is key to increasing crop yield and for bioengineering. Kobe University research is making progress in studying the genetic regulation of the process in ...

In plants, flowering is a crucial process for reproductive success and continuity of the species through time. Fruit production requires the perfect development of reproductive structures. Abscission, ...
