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 ...

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 ...

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 ...

Scientists have discovered that a plant hormone called auxin is responsible for development of the egg cell in a plant's embryo sac. In unraveling this fundamental issue in plant biology, the work ...

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 ...

Researchers have discovered an ancient plant species whose reproductive biology captures the evolution from one to two spore sizes -- an essential transition to the success of the seed and flowering ...

Researchers at Purdue University and UC Davis have found that petunias cannot properly form reproductive structures without chemical signals delivered between different parts of the plant. The work ...

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 ...

Plants, as the base for ecological food chains, serve as the structural and functional foundation of natural and managed systems. The study of plant science and biotechnology provides opportunity in a ...
