Physiological implications of legume nodules associated with soil acidity

摘要: The mutualistic legume-rhizobia symbiosis that leads to nodule formation and ensuing nitrogen fixation is of great importance soil health agriculture sustainability. processes nodulation can improve the nitrogenous content overall structure rhizosphere; however, they are highly sensitive environmental parameters, such as acidity. Indeed, low pH conditions appreciably diminish benefits associated with legumes decrease their biomass yields. This considerable economic agricultural legume crop pasture species commonly grown on acidic soils. Acidic growing reduce fitness both host rhizobia partner, in addition directly hindering establishment structures. includes impairing signal exchange between two symbiotic partners inhibiting ability express critical genes. effect acidity growth addressed here, a focus development function. Practices help overcome limitations environments addressed, an emphasis how current biotechnology molecular genetic approaches could aid overcoming negative effects pH.
