Experiments show that a wild-rice gene can help cultivated rice recover beneficial root microbes reduced during domestication.<\/p>\n

From 113 candidates, researchers selected the receptor-like kinase gene OsRLK and tested it with knockouts, overexpression lines and a synthetic microbial community.<\/p>\n

How candidates were found<\/h2>\n

Two recombinant inbred populations from wild rice crossed with japonica and indica rice were compared in fields. Rhizosphere profiles, quantitative-trait loci, genomes from 382 accessions and expression data narrowed the genes linked to ancestral microbes.<\/p>\n

Which microbes changed<\/h2>\n

OsRLK was strongly associated with Acinetobacter linked to nitrogen uptake. When overexpression and knockout plants received the same synthetic community, root-community composition and nitrogen-related responses shifted with the gene.<\/p>\n

What field trials showed<\/h2>\n

Overexpression lines improved yield-related traits under field conditions. One setting and genetic background cannot guarantee the same yield everywhere. Acinetobacter species and strains also differ, so a genus name alone does not prove a benefit.<\/p>\n

What comes next<\/h2>\n

Breeding tests must show stable microbial recruitment across soils and quantify any real fertilizer reduction. Non-target microbes, greenhouse-gas effects, long-term yield and biosafety also need testing before commercial claims are justified.<\/p>\n
