RALEIGH, N.C. – Hardly articulate, the tiny strangleweed, a pale parasitic plant, can sense the presence of friends, foes, and food, and make adroit decisions on how to approach them.

Mustard weed, a common plant with a six-week life cycle, can't find its way in the world if its root-tip statolith - a starchy "brain" that communicates with the rest of the plant - is cut off.

 

SMARTS? The field of plant neurobiology is finding signs of intelligence across the flora spectrum.

The ground-hugging mayapple plans its growth two years into the future, based on computations of weather patterns. And many who visit the redwoods of the Northwest come away awed by the trees' survival for millenniums - a journey that, for some trees, precedes the Parthenon.

 

As trowel-wielding scientists dig up a trove of new findings, even those skeptical of the evolving paradigm of "plant intelligence" acknowledge that, down to the simplest magnolia or fern, flora have the smarts of the forest. Some scientists say they carefully consider their environment, speculate on the future, conquer territory and enemies, and are often capable of forethought - revelations that could affect everyone from gardeners to philosophers.

 

Indeed, extraordinary new findings on how plants investigate and respond to their environments are part of a sprouting debate over the nature of intelligence itself.

 

"The attitude of people is changing quite substantially," says Anthony Trewavas, a plant

 

biochemist at the University of Edinburgh in Scotland and a prominent scholar of plant intelligence. "The idea of intelligence is going from the very narrow view that it's just human to something that's much more generally found in life."

 

To be sure, there are no signs of Socratic logic or Shakespearean thought, and the subject of plant "brains" has sparked heated exchanges at botany conferences. Plants, skeptics scoff, surely don't fall in love, bake soufflés, or ponder poetry. And can a simple reaction to one's environment truly qualify as active, intentional reasoning?

 

But the late Nobel Prize-winning plant geneticist Barbara McClintock called plant cells "thoughtful." Darwin wrote about root-tip "brains." Not only can plants communicate with each other and with insects by coded gas exhalations, scientists say now, they can perform Euclidean geometry calculations through cellular computations and, like a peeved boss, remember the tiniest transgression for months.

 

To a growing number of biologists, the fact that plants are now known to challenge and exert power over other species is proof of a basic intellect.

 

"If intelligence is the capacity to acquire and apply knowledge, then, absolutely, plants are intelligent," agrees Leslie Sieburth, a biologist at the University of Utah in Salt Lake City.

 

For philosophers, one of the key findings is that two cuttings, or clones, taken from the same "mother plant" behave differently even when planted in identical conditions.

 

"We now know there's an ability of self-recognition in plants, which is highly unusual and quite extraordinary that it's actually there," says Dr. Trewavas. "But why has no one come to grips with it? Because the prevailing view of a plant, even among plant biologists, is that it's a simple organism that grows reproducibly in a flower pot."

 

But here at the labs on the North Carolina State campus, where fluorescent grow-rooms hold genetic secrets and laser microscopes parse the inner workings of live plants, there is still skepticism about the ability of ordinary houseplants to intellectualize their environment.

 

Most plant biologists are still looking at the mysteries of "signal transduction," or how genetic, chemical, and hormonal orders are dispersed for complex plant behavior. But skeptics say it's less a product of intelligence than mechanical directives, more genetic than genius. Some see the attribution of intelligence to plants as relative - an oversimplification of a complex human trait.

 

And despite intensifying research, exactly how a plant's complex orders are formulated and carried out remains draped in leafy mystery.

 

"There is still much that we do not know about how plants work, but a big part of intelligence is self-consciousness, and plants do not have that," says Heike Winter Sederoff, a plant biologist at N.C. State.

 

Still, a new NASA grant awarded to the university to study gravitational effects on crop plants came in part due to new findings that plants have neurotransmitters very similar to humans' - capable, perhaps, of offering clues on how gravity affects more sentient beings. The National Science Foundation has awarded a $5 million research grant to pinpoint the molecular clockwork by which plants know when to grow and when to flower.

 

The new field of plant neurobiology holds its first conference - The First Symposium on Plant Neurobiology - in May in Florence, Italy.

 

The debate is rapidly moving past the theoretical. In space, "smart plants" can provide not only food, oxygen, and clean air, but also valuable companionship for lonely space travelers, say some - a boon for astronauts if America is to go to Mars. Research on the workings of the mustard weed's statolith, for example, may one day yield a corn crop with 1-3/8 the gravitational force of Earth.

 

Some Earth-bound farmers, meanwhile, see the possibility of communicating with plants to time waterings for ultimate growth. A new gene, Bypass-1, found by University of Utah researchers, may make that possible.

 

Still, it can be hard for the common houseplant to command respect - even among those who study it most closely.

 

"When I was a postdoc, I had a neighbor who watched me buy plants, forget to water them, and throw them out, buy them and throw them out," says Dr. Sieburth. "When she found out I had a PhD in botany, I thought she was going to die."

I recommend the book

THE SECRET LIVES OF PLANTS.

So sorry, but I have no author at hand.

In this book, you find many examples of plant consciousness, for instance one about plant pathologists from the labs of the Agricultural Dept.

These people burn every specimen of plant they get, to determine their mineral content. when they were brought inside a room with plants, these plants 'shut down'- they do not give any reaction at all.

If you decide to cut off a plant's leaves, it will give a reaction at the mere thought.

all this was measured with a lie-detector.

I hope they have a master plan for the future of this planet. Because man seems to be a little slow on the uptake.

 

While I was gardening the other day, I was wondering if plants had any communication with the demigods, because they often just die a merciless death in droughts.

I have to admit it is amazing how they respond to a little love and respect.

It also is a cause for some wonder how Srimati Tulasi devi chooses to serve in such a way, that even Srimati Radharani gives credit to her for her own dedication to Krsna.

I have this book and read most of it. Truly fascinating. This universe is far more amazing than people can imagine.

I saw this demonstrated on tv in the late sixties. Somehow the plants can perceive our intentions. Amazing really. That instrument was developed by Jagadish Candra Bose around the 1890's or early 1900's.

 

A man ahead of his time even for a scientist. Anything that can help understand and become aware of the all-pervasiveness of life is very good.

TRANSLATION

This individual soul is unbreakable and insoluble, and can be neither burned nor dried. He is everlasting, present everywhere, unchangeable, immovable and eternally the same.

 

 

Present everywhere. We are living in an ocean of eternal life. Learning to see past the coverings is the trick.

J.C. Bose challenged the blurred line between living things and non-living things. He demonstrated that even so-called non-living things like metals respond to different stimuli. The only things lacking were sensitive instruments to empirically record those responses, and an open-mind to think the seemingly impossible.

 

Once, in front of a packed audience he sent radio waves that traveled through a wall to ring an electric bell 75 feet away. In one stroke, he ushered in the world of wireless as we know it. Two years latter, Marconi based his wireless on the work of Bose and got Nobel prize.

 

Bose knew about patents and could have patented his finding of wireless, but he never supported the idea of patenting.

 

Bose proclaimed, on a few occasions, that his work was not new, that the ancient sages and saints of India knew these undiscovered secrets of nature thousands of years ago and he was merely re-discovering them for himself.

Yes it is a blurred line. Mankind has barely opened its eyes enough to see life in anything other than born humans let alone everything else. Some still consider animals to be no more than biological machines with no sense of an independent I am. They will even argue the same about unborn humans and even humans in general. What to speak of plants.

 

I finally got a copy of the Secret Life of Plants by Thompkins and Bird. I love libraries. The first chapter is called Plants and ESP. This man named Baxter also proved that plants have a very high level of sentience through the use of a polygraph. Just after reading this one chapter I will never look at plant life the same again. Great book so far. Thanks to those that brought it up.

 

"...an open mind to think the seemingly impossible" is right. I always thought I had an open mind but this is a test. I really became aware of something within myself yesterday in a new way. A deep seated fear to become aware of the all pervasiveness of life. I have actually become accoustomed and comfortable to the idea that I am surrounded by the dead and inert. Makes me feel like I am just the tinest of sprouts who has just begun to emerge from the soil, irrestibly drawn to the sun, but not knowing what to expect.
