It's a Jungle Out There! How Plants Communicate to Get Their Needs Met

Do plants really communicate with each other? What is really happening in their words, but a dynamic world? Are they like some of their neighbors better than others? Are they really able to fend off insects attack? Over the past 10 years, with some fascinating research delved into what is actually happening in the plant communities and interactions within and between different species of plants and even insects. Studies have also documented a lively communication between plants and microbes - such as fungi and bacteria - the proportion of living space in the root zone of plants. Other studies have shown that there are overhead mechanisms plants use to signal each other, often in times of trouble.

...

Scientists have discovered that in many cases, the chemical communicators are secreted from the roots of plants. When I was a student in horticulture, our research team looked at what proved to be a positive outcome of this type of interaction. We grew the seeds of 250 strains of old, never hybridized garden pea (Pisum sativum) in test tubes also contain a common weed seeds. Wow! We were delighted by the fact that 13 strains (originating from countries such as Ethiopia, Nigeria, and Peru) was killed invading weeds through natural herbicides, such as chemicals given off its roots.

Can plants protect themselves from the population of potentially deadly germs? Although we still have a lot to learn about these complex interactions, we also have some answers. The plants are remarkable natural ways to fending for themselves. They are often faced with an arsenal of attack pathogens and win in the struggle to create their own chemical weapons to secrete from their roots. On the battlefield, they are 'front line' of the family, but living cells (aptly called boundary cells) that give off a dizzying array of biological chemicals that thwart the progress of the enemy.


Plants are dependent on the 'good guy' bacteria and fungi that live in the root zone to provide biological control of diseases. That is why it is always a good idea to use non-chemical measures to prevent and minimize damage caused by the disease as possible, relying on chemical controls only as a last resort. As we learn more about what makes plants tick 'we can better appreciate the mutually beneficial nature of plants and microscopic organisms. Fungi that form symbiotic relationships with plant roots in natural settings (mycorrhizae) were found to enhance water and nutrient intake biljaka.Najčešći they enter the stem cell is estimated to be 80-90% of trees, shrub, flower, grass and crop plant species found on earth.A fascinating form of plant-to-plant communication are used for defense against insects include 'conversation' between different plant species.


is an example of a recent experiment carried out by researchers at the University of California, Davis, who performed surgery on sagebrush leaves to mimic the insect štetu.Podrezan sagebrush responded by sending out a chemical SOS signals, picked up a neighboring tobacco plants. On the other hand, tobacco plants cranked out large amounts of enzymes that greatly reduced the tastiness of their leaves. Their intelligence is paid off. Many hungry grasshoppers and caterpillars soon discovered that what was once a favorite restaurant really gone downhill. It is not too discouraged, most traces of the far more palatable to grow tobacco with unclipped sagebrush! (In fact, tobacco plants near clipped sagebrush is 60% less damage than plants near pristine sagebrush .)

There has never been a better opportunity for scientists to apply the lessons learned from the nature of communication systems, modern agricultural and horticultural urban settings than in today svijetu.Brzo broader base of knowledge will probably lead to more biological control of pests, reduce reliance on synthetic pesticides, breeding and selection of resistant varieties and genetically modified plants that are able to avoid or keep attacking organisms.
