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 research collaboration has demonstrated the function of a genetic pathway for anther development, with this pathway proven in 2019 work to be present widely in the flowering plants that evolved over ...

Plant reproduction plays a vital role in our food systems and the balance of ecosystems, yet it remains a complex process. Plants exhibit a range of reproductive strategies: some are strictly male or ...

This separation of sexes in plants is called dioecy. One reason why dioecy may evolve is because of the negative effects that ...

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 ...

Organ pipe cactus (Stenocereus thurberi) is one of three species of bat‐pollinated columnar cacti that co‐occur along the Gulf Coastal region of the Sonoran Desert in northwestern Mexico. Its ...

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 ...

Terrestrial plants began making a permanent home on land from the sea at least 420 million years ago. Updated methodologies in genetic data research has determined this number could be as old as 500 ...

Background and aims The transition from outcrossing to selfing is a repeated pattern in angiosperm diversification and according to general theory this transition should occur quickly and mixed ...
