Soils in many areas suppress certain plant diseases. Understanding the basis for this disease suppressiveness could lead to improved plant health in less favorable areas. Some forms of disease suppression may be caused by bacteria in the genus Pseudomonas which aggressively colonize root surfaces. Increased plant growth and yield are closely associated with the capacity of some of these bacteria to produce iron-binding compounds called siderophores. This article addresses the biological characteristics of these soil-bome root epiphytes, their contribution to plant health, and their potential use in biotechnology.
许多地区的土壤能抑制某些植物病害。了解这种抑病性的基础原理，可能会使在条件较差的地区提高植物健康水平成为可能。某些形式的病害抑制可能是由假单胞菌属的细菌引起的，这些细菌会积极地定植在根表面。一些细菌产生的铁结合化合物（称为铁载体）与增加植物生长和产量密切相关。本文介绍了这些土生根外生菌的生物学特性、它们对植物健康的贡献，以及它们在生物技术中的潜在应用。
