The effect of SLs on heavy metals in rice.

Treatment	Application	Effect	References
As	SL deficient rice	Severe growth abnormalities in trigolactone-deficient mutants while wild type showed reduced As uptake and accumulation and reduced phosphate-transporters encoding gene expression, enhanced transcript accumulation of CAT, SOD and APX genes and lowered expression of phosphate tranporter genes.	[55]
Cd or As	GR24	Effectively inhibited Cd or As uptake by rice plants but Cd accumulation and translocation from root to shoot was not decreased.	[58]
-	SLs	Play an active role in structuring rhizomicrobiome and mediation of distinct metabolic pathway.	[53]
Phosphate deficiency	Exogenously applied GR24 (1 µM)	GR24 restored normal leaf senescence in SL-deficient mutants.	[54]
