Latest Plant hormones Stories

2014-04-16 12:17:44

Floods and droughts are increasingly in the news, and climate experts say their frequency will only go up in the future. As such, it is crucial for scientists to learn more about how these extreme events affect plants in order to prepare for and combat the risks to food security that could result. Like animals, plants have hormones that send chemical signals between its cells relaying information about the plant's development or interactions with the outside world. One particular way in...

Broccoli With Better Anti-Cancer Benefits And Longer Shelf Life
2014-02-11 09:46:54

University of Illinois College of Agricultural, Consumer and Environmental Sciences (ACES) While researching methods to increase the already well-recognized anti-cancer properties of broccoli, researchers at the University of Illinois also found a way to prolong the vegetable’s shelf life. And, according to the recently published study, the method is a natural and inexpensive way to produce broccoli that has even more health benefits and won’t spoil so quickly on your refrigerator...

A tiny weed reveals an unexpected chemical connection between hormone pathways You might think you have nothing in common with mustard except hotdogs. Yet based on research in a plant from the mustard family, Salk scientists have discovered a possible explanation for how organisms, including humans, directly regulate chemical reactions that quickly adjust the growth of organs. These findings overturn conventional views of how different body parts coordinate their growth, shedding light on...

Ferns Herbivore Defense
2012-11-21 13:00:05

Max Planck Institute for Chemical Ecology Unlike flowering plants, bracken ferns do not release any odor signals to attract the enemies of their attackers for their own benefit. They dominated the earth for 200 million years and numerous different species can still be found all over the world: mosses, horsetails and ferns. Researchers from the Max Planck Institute for Chemical Ecology in Jena, Germany, have now found out that bracken ferns (Pteridium aquilinum) do not release any...

Crops Possibly Protected From Stressors Due To New Discovery
2012-08-31 16:37:30

Salk findings of a key genetic mechanism in plant hormone signaling may help save crops from stress and help address human hunger Scientists at the Salk Institute for Biological Studies have discovered a key genetic switch by which plants control their response to ethylene gas, a natural plant hormone best known for its ability to ripen fruit, but which, under stress conditions, can cause wilted leaves, premature aging and spoilage from over-ripening. The findings, published August 30 in...

Light is not only the source of a plant's energy, but also an environmental signal that instructs the growth behavior of plants. As a result, a plant's sensitivity to light is of great interest to scientists and their research on this issue could help improve crop yields down the road. Similarly understanding a plant's temperature sensitivity could also help improve agriculture and feed more people. Two new papers from Carnegie's Zhiyong Wang laboratory identify key aspects of the hormonal...

International collaboration puts molecular face on enzyme family that allows plants to adjust quickly to herbivore attack or changes in growing conditions Science has known about plant hormones since Charles Darwin experimented with plant shoots and showed that the shoots bend toward the light as long as their tips, which are secreting a growth hormone, aren´t cut off. But it is only recently that scientists have begun to put a molecular face on the biochemical systems that...

Tobacco Plants Advertise They Are Ready To Attack Leafhoppers
2012-05-23 10:25:32

Like blood-sucking insects, herbivores evaluate their host's readiness for defense Tobacco: actually pretty bad food for leafhoppers Empoasca sp. is not a typical pest of wild tobacco (Nicotiana attenuata). When this plant grows in its natural habitats in North America, however, it is attacked by tobacco hornworm larvae (Manduca sexta). This specialist insect is resistant to the toxic nicotine, which the plant produces as a defense against its enemies. When researchers from the Max...
