This article addresses the lifestyle of Pseudomonas and focuses on how Pseudomonas putida can be used as a model system for biotechnological processes in agriculture, and in the removal of pollutants from soils. In this chapter we aim to show how a deep analysis using genetic information and experimental tests has helped to reveal insights into the lifestyle of Pseudomonads. Pseudomonas putida is a Plant Growth Promoting Rhizobacteria (PGPR) that establishes commensal relationships with plants. The interaction involves a series of functions encoded by core genes which favor nutrient mobilization, prevention of pathogen development and efficient niche colonization. Certain Pseudomonas putida strains harbor accessory genes that confer specific biodegradative properties and because these microorganisms can thrive on the roots of plants they can be exploited to remove pollutants via rhizoremediation, making the consortium plant/Pseudomonas a useful tool to combat pollution.

本文介绍假单胞菌的生活方式，并着重介绍恶臭假单胞菌如何用作农业生物技术过程以及从土壤中去除污染物的模型系统。在本章中，我们旨在展示使用遗传信息和实验测试的深入分析如何帮助揭示对假单胞菌生活方式的见解。恶臭假单胞菌（Pseudomonas putida）是一种促进植物生长的根际细菌（PGPR），它与植物建立了共生关系。相互作用涉及由核心基因编码的一系列功能，这些功能有利于营养素动员，防止病原体发育和有效的生态位定植。某些恶臭假单胞菌菌株带有赋予特定生物降解特性的辅助基因，并且由于这些微生物可以在植物的根部上繁衍，因此可以利用它们通过根际修复来去除污染物，从而使联合体植物/假单胞菌成为对抗污染的有用工具。
