Tobacco Plants That Stay Young Forever - Science News - redOrbit | Erba Volant - Applied Plant Science | Scoop.it

Tobacco plants bloom when they are just a few months old – and then they die. Now, researchers have located a genetic switch which can keep the plants young for years and which permits unbounded growth.

"Just like humans, plants suffocate and die," Gilroy says. "Plants can grow in space, but it may be that they don't grow very well. And one of the reasons is trying to cope with this oxygen depletion."

Scientists join forces to bring plant movement to light | e! Science News | Erba Volant - Applied Plant Science | Scoop.it
Leading plant scientists explore one of the most fundamental processes in plant biology -- plant movement in response to light, water, and gravity -- in a January Special Issue of the American Journal of Botany. Plant movements, known as tropisms, are crucial for plant survival from the second a plant germinates to how a plant positions its flowers for pollinators and seed dispersal.

Newly Discovered Carnivorous Plant Eats Prey Underground

Newly Discovered Carnivorous Plant Eats Prey Underground | Erba Volant - Applied Plant Science | Scoop.it

While studying the plants with the Philcoxia genus – native to the tropical savannah region of Cerrado – in Brazil, scientists were puzzled by one apparent paradox: the plants appeared to have flesh-eating features, but there was no evidence of prey being trapped. Recently, a team of researchers found the explanation, published this week in the Proceedings of the National Academy of Sciences: the plant captures and devours its victims through leaves buried in the sand.

 

It’s the first time that researchers find a plant of this kind, though it is believed that many other species with similar characteristics may be discovered now. It is currently accepted that 0.2% of flowering plant species are carnivorous, but the percentage may be incremented due to the new finding, authors say.

 

“This leads to the question of whether there are other carnivorous plants out there in families not known for carnivory,” says Peter Fritsch, a botanist and curator at the California Academy of Sciences in San Francisco, US, and co-author of the research.

 

This peculiar way of capturing worms may be a result of evolution, given the fact that the region of Cerrado where the plants live is covered with rocky outcrops and sand, and therefore spare in nutrients. The researchers, coming from different universities and laboratories in Brazil, Australia and the US, will now study how other plants search for nutrients in relatively desolate landscapes.

Very Chilly Cushions – A Common Plant Adaptation to Life in the Cold

Very Chilly Cushions – A Common Plant Adaptation to Life in the Cold | Erba Volant - Applied Plant Science | Scoop.it
I am not sure why, but lately I’ve been thinking a lot about how plants adapt to extremes of cold, both in the arctic and the alpine regions. I’m sure it has nothing to do with the fact...
