An altruistic rhizo-microbiome strategy in crop-rotation systems for sustainable management of soil-borne diseases.

ABSTRACT: Crops leave a soil legacy with altruistic effects for subsequent crops but not for themselves. While research has focused on improvements in soil physicochemical properties and the suppression of non-host pathogens, the altruistic microbiome and its assembly mechanism driven by root exudates remain largely unknown. Here, we identified altruistic but self-detrimental phenomena when garlic was rotated with other crops based on meta-analysis and in vivo experiments. Studies utilizing a globally adopted garlic-pepper rotation system demonstrated density-dependent enrichment of key microbial taxa, especially the Penicillium genus, which supports the healthy growth of non-Allium plants but exhibits pathogenicity toward garlic. Furthermore, we found that garlic roots stably secrete diallyl disulf
