How plants communicate using the underground information superhighway.

چکیده
The rhizosphere is a densely populated area in which plant roots must compete with invading root systems of neighboring plants for space, water, and mineral nutrients, and with other soil-borne organisms, including bacteria and fungi. Root-root and root-microbe communications are continuous occurrences in this biologically active soil zone. How do roots manage to simultaneously communicate with neighboring plants, and with symbiotic and pathogenic organisms within this crowded rhizosphere? Increasing evidence suggests that root exudates might initiate and manipulate biological and physical interactions between roots and soil organisms, and thus play an active role in root-root and root-microbe communication.

N orth American futurists and politicians alike see development of an electronic infrastructure for an information superhighway as an important national goal, much like development of railroads and other transportation systems in the 19th century. The information superhighway is supposed to enhance communications and commerce and lead to development of a modern information economy and a sophist...

متن کاملUpdate on Biotic Interactions in the Rhizosphere Biotic Interactions in the Rhizosphere: A Diverse Cooperative Enterprise for Plant Productivity
Microbes and plants have evolved biochemical mechanisms to communicate with each other. The molecules responsible for such communication are secreted during beneficial or harmful interactions. Hundreds of these molecules secreted into the rhizosphere have been identified, and their functions are being studied in order to understand the mechanisms of interaction and communication among the diffe...
متن کاملInterplant Communication of Tomato Plants through Underground Common Mycorrhizal Networks
Plants can defend themselves to pathogen and herbivore attack by responding to chemical signals that are emitted by attacked plants. It is well established that such signals can be transferred through the air. In theory, plants can also communicate with each other through underground common mycorrhizal networks (CMNs) that interconnect roots of multiple plants. However, until now research focus...
متن کاملSteering Strategic Decisions at London Underground: Evaluating Management Options with System Dynamics
System dynamics simulation models provide a powerful and rigorous means of evaluating management options in dynamically complex settings such as a metro subway system. This paper explores how a system dynamics model has been used over several years to address a variety of management challenges at London Underground. Several short case illustrations are described to demonstrate how such models a...
