A translocation in which part of one chromosome is exchanged with a part of a separate non-homologous chromosome. ~ s are the result of moving a section of the genetic material (chromosome) of the cell and attaching it to another chromosome.
Plants actually create these compounds to ensure a healthy, diverse population of bacteria lives near their roots to protect the plants. Decomposers are especially important in retaining nutrients in their cells thus preventing loss of those nutrients from the root zone. This is very important in the nitrogen cycle.
Each organism receives something from the other and gives back something in return. Rhizobia bacteria provide the legume plant with nitrogen in the form of ammonium and the legume plant provides the bacteria with carbohydrates as an energy source. The rate of N2-fixation is directly related to legume plant growth rate.
