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 ...

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 ...

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 ...

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 ...

Researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular “highways” that ensure the growth and functionality of the male ...

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 ...

The colonisation of land by plants was one of the most important evolutionary steps on earth; it subsequently affected all other terrestrial evolutionary processes. Leaving the aquatic environment ...

A long-standing mystery surrounding a fundamental process in plant biology has been solved by a team of scientists at the University of California, Davis. The group's ground-breaking discovery that a ...
