Chlorella vulgaris aqueous extracts are used for enhancing C. longa plant growth and rhizome yield. In C. longa, Chlorella vulgaris foliar spraying stimulates plant growth and yield, as well as changing the compositions of bioactive compounds. Plant growth, yield, photosynthetic pigment concentration, and nitrogen content all improved when the Chlorella vulgaris aqueous extract was added to the foliar spray. The CURS-1, -2, -3, and DCS genes were revealed to be differently upregulated by the Chlorella vudgaris aqueous extract treatments. The curcuminoid content (hisdenethoxycurcumin, dimethoxycurcumin, and curcumin) also increased when the plant was sprayed with the Chlorella vulgaris aqueous extract, which corresponded with the curcuminoid gene's expression level.
