Plants Know Their Relatives And Like Them!
Plants Know Their Relatives And Like Them!

Unlike many human brothers and sisters, plant siblings appear to do their best to get along, sharing resources and avoiding competition.

In a study of more than 3,000 mustard seedlings, scientists discovered that the young plants recognize their siblings other plants grown from the seeds of the same momma plant using chemical cues given off during root growth. And it turns out mustard plants wont compete with their brethren the way they will with strangers: Instead of rapidly growing roots to suck up as much water and minerals as possible, plants who sensed nearby siblings developed a shallower root system and more intertwined leaves.

Its possible that when kin are grown together, they may balance their nutrient uptake and not be greedy, plant biologist Harsh Bais of the University of Delaware said in a press release. The work will be published in an upcoming issue of Communicative and Integrative Biology.

Two years ago, co-author Susan Dudley of McMaster University in Canada observed a similar pattern in the sea rocket, a common seashore plant that also appears to favor its siblings. But the initial studies of kin recognition have been criticized for failing to control for complicating factors, such as resource depletion caused by competition between the unrelated plants. And until now, the researchers didnt know how plants managed to identify their kin.

As seedlings grow, their developing root system gives off a variety of chemical signals, and the researchers guessed that these secretions might play a role in sibling recognition. To test their theory, the scientists grew wild Arabidopsis thaliana in a sterile liquid containing root extracts from sibling plants, unrelated plants or their own roots. Because each plant was grown in a highly controlled setup, the researchers could be sure any changes in growth were due to differences in the root extracts.

Edited on Thu Oct-15-09 07:45 PM by BrklynLiberal
how much "consciousness" plants do have...

Amazing book.....



THE SECRET LIFE OF PLANTS by Peter Tompkins and Christopher Bird is a wonderful book of wisdom about the plant world and life in general. Like many people my age, I cut my teeth on Disney's "Living Desert" back in the 1950s. That film killed the notion for me that nothing lives in Death Valley and if Death Valley can be alive what else is possible?

SECRET LIFE is like the old Disney films because the book describes science that challenges stereotypical mainstream thinking. Anyone who believes plants are sentient beings will love this book. If you've done much reading on this subject you've probably seen Tompkins and Bird quoted elsewhere.

In the first part of their book, the authors explore the attributes of plants and pretty much conclude they have everything in common with animals-except plants probably came first on the evolutionary ladder and prepared the way for animals. In fact, if earth was invaded by alien species, the authors suggest the aliens were probably plants. But, you say, plants have roots and stay put (for the most part) and plants produce chlorophyll. Shell fish (oysters, mussels) and sea anemones can be rooted to one spot and small protozoa-like creatures produce chlorophyll.

Probably the thing I like the best about this book is that finally, someone links the Chakras to real body parts-the seven endocrine centers--and explains the reasons why these "hot spots" are so important. Also, Tompkins and Bird explain the scientific reasoning behind Bach flower remedies and many other "new age" products you can find at Fresh Fields and other holistic stores.

Skeptics will always have doubts, but after 30 years of organic gardening and non-academic exposure to plants, I know Tompkins and Bird are onto something. So do many modern scientists who have discovered belatedly that much of what the authors described 30 years ago may be true afterall.

Cutting edge scientists are frequently ignored. Once upon a time some people thought George Washington Carver was a fruitcake because he thought plants had feelings (they do). Carver discovered many unusual things as did a number of other later Nobel winners, although sometimes folks like Gregor Mendel were not recognized until it was too late.

If you want to be a better person, a wiser consumer, a great gardener, and healthier, you owe it to yourself to read THE SECRET LIFE OF PLANTS. It isn't all about them.

28. Just because plants react to the enviroment doesn't make them "sentient"
Edited on Sat Oct-17-09 08:59 PM by Odin2005
Plant "behavior" is the result of hormones and cell and tissue-level interactions.

Chakras? :eyes:

Plants don't need sentience, nervous systemsare metabolically expensive and are not necessary when you don't move and hormones and cell-level processes are just as fine.

25. The heads of the Social Darwinists just exploded.
Too bad for them that biologists as far back as Darwin himself described how natural selection could create altruistic behavior. That was all ignored by people who liked the "nature red in tooth an claw" oversimplification of natural selection because it conformed with the ideological prejudices of the day.

27. And E.O. Wilson came along in the 1970s with Sociobiology.
Talked about altruistic behavior to keep the species going.

(Biology major here.) :D
