Title

Silicon modification improves biochar’s ability to mitigate cadmium toxicity in tomato by enhancing root colonization of plant-beneficial bacteria

Other claims from this paper (10)

Observation Silicon modification altered biochar physicochemical properties.
Observation Silicon-modified biochar contained more silicon.
Intervention effect Silicon-modified biochar increased plant-available soil silicon.
Mechanism Microbiome transplant results indicated rhizosphere microbiome changes contributed to mitigation of cadmium toxicity by biochar.
Intervention effect Raw biochar altered tomato rhizosphere bacterial community composition.
Intervention effect Silicon-modified biochar altered tomato rhizosphere bacterial community composition differently from raw biochar.
Intervention effect Both biochars promoted Sphingomonas, Lysobacter and Pseudomonas, especially silicon-modified biochar.
Observation Cultured bacteria promoted by biochar mitigated cadmium toxicity in tomato.
Intervention effect Both biochars stimulated tomato recruitment of beneficial bacteria, with a stronger effect from silicon-modified biochar.
Mechanism The authors inferred biochar benefits to beneficial bacteria were partly mediated through tomato.
