plants communication?

Question

I've just saw that plants can communicate between them .
where can I find good info. about it ?

Answer 1

Plants are proficient at volatile production and release at great cost to themselves so there must be an adaptive function to the floral essences from leaves as well as fruit and flowers. In the past it was suggested it was primarily to control temperature. "The old English custom of covering brick walls with sprigs of rosemary for cooling has been supported by modern research, which shows rosemary has 74 times the cooling effect of fresh air (thyme has 68 times the cooling effect, lavender 60 times)."

However many volatiles are released only when the plant is attacked or seasonally. Only ethylene, was previously known to travel through the atmosphere to activate plant defensive genes. But when methyl jasmonate is topically applied to tomato plants it induces defensive proteins in the treated plants and in nearby plants as well. This paper shows that if Sage (Artemisia tridentata), a plant that has methyl jasmonate is grown in a closed green house with tomato plants, the same defensive mechanism is triggered. This demonstrates interplant communication occurs between species to activate the expression of defensive genes.

Interplant mycorrhizal connections may allow the transfer of signaling molecules as well as nutrients.

A well known occurrence is mass or gregarious flowering. Plietesial plants like bamboo grow for a number of years, flower gregariously, set seed and then die others flower every few years in repeated synchrony. The term from old European forests is mast flowering, named for Oak mast (acorns). Botanically it is called iteroparity when plants have offspring at intervals throughout their life cycle.
Certain clumping bamboos also reproduce in this episodic manner but once they flower they die. Historic mass flower and death in bamboo occurred in 919 & 1114 in China. In Japan it was 1716 & 1845 when the plants died. Since then the Phyllostachys bamboos have been growing in Europe and America. In 1960's stocks all over the world flowered, set seed, and died. These plants appear to have about 120 year seed cycle that is communicated across enormous spaces. An Asian bamboo species, Melocanna baccifera, erupts in flowers about every forty-eight years, an event known as the Mautam. The timing mechanism is unknown but the adaptive purpose has been postulated.
While the plant is in bloom it attracts herbivores that will eat the seeds. If to many are eaten before seeds drop and the plant dies it will die out. In mass flowering herbivores will still be attracted but there will be so many seeds that any one plant will still have a good chance of its seeds germinating. This is called predator satiation. Combined with the long interval between flowering prevents the predator population from surviving in high numbers between bloom years. While if plants produced a consistently healthy crop of seeds every year, populations of seed eaters would rise to the point where all the seeds would be eaten no matter how numerous. None would remain to grow. So the plants may be keyed to their seed eater population density. When the attacks drop below a certain level volatiles are not produced and this may stop repressing flowering. So why did bamboo aquire such a long interval? this may be manmade due to gardening. The clumps are regularly split and used in ornamental plantings. If this repeated disturbance caused repressive volatiles the natural periodicity may have been increased in response.

Answer 2

Plant communication is observed (a) within the plant organism, i.e. within plant cells and between plant cells, (b) between plants of the same or related species and (c) between plants and non-plant organisms, especially in the rootzone. Plant roots communicate in parallel with rhizobia bacteria, with fungi and with insects in the soil. This parallel sign-mediated interactions which are governed by syntactic, pragmatic and semantic rules are possible because of the decentralized "nervous system" of plants. As recent research shows 99% of intraorganismic plant communication processes are neuronal-like. Plants also communicate via volatiles in the case of herbivory attack behavior to warn neighboring plants. In parallel they produce other volatiles which attract parasites which attack these herbivores. In stress situations plants can overwrite the genetic code they inherited from their parents and revert to that of their grand- or great-grandparents.

Answer 3

heck yess.. my chile plant do not like the pepermint so they get stickey.. and the tea it tends to browns with the garlic around.. so yes they have their way of communication..

Answer 4

I think u can look at the link shown below.

Answer 5

"The force is a mystical energy field that binds all living things . . ." lol - i'm not sure, but it would be interesting to know if that is ture.
