“土壤免疫力”是最近几年发展起来的概念，用以描述土壤通过调节功能微生物的活动抵抗病原物侵染保持内部稳定性的能力。最近，王丽琨博士与李小方研究员在Critical Reviews in Microbiology发表概念论文，将土壤面临病原菌侵害和污染物毒害后所表现的恢复能力统一纳入到了“土壤系统恢复力”的概念中，进一步丰富了土壤作为“viable entity”的学科认知。
The role of soil microbiome and plant genetics in suppressing soil-borne pathogens and reducing contamination (taking heavy metals as an example).①Pathogen antagonistic microbes in soil inhibit the infection of soil-borne pathogens into plant root systems. ②In a specific genotype of plants, adsorption of heavy metals induces the defense responses of plant host against pathogen. ③Plant exudates attract beneficial microorganisms. ④In a specific genotype of plants, adsorption of heavy metals increases the susceptibility of plant towards pathogens, and the plant host failed to secrete particular root exudates to recruit beneficial microorganisms.
