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 ...

Imagine a photograph of your great-grandparents, grandparents and parents side by side. You’d see a resemblance, but each generation would look distinct from its predecessors. This is the process of ...

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 ...

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, ...

Imagine a photograph of your great-grandparents, grandparents and parents side by side. You'd see a resemblance, but each generation would look distinct from its predecessors. This is the process of ...

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 ...

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 ...

Challenge 1. Goldenrod and Gall Identification: Students must learn to identify the goldenrod that they choose to study and the types of galls on plants in their study system; in SE Pennsylvania, I ...
