Summary of results. Ovals represent gene abbreviations. Rectangles represent key compounds. The histogram shows the relative content of key factors. Wild-type (n = 3) is shown in blue, HrHEMA overexpression (n = 3) is shown in red, HrPOR overexpression (n = 3) is shown in green, and HrCAO overexpression (n = 3) is shown in purple. * represents p < 0.05, ** represents p < 0.01; # represents p < 0.05, compared with 2000 lx; & represents p < 0.05, compared with 6000 lx of the same gene. ALA, aminolevulinic acid; Chla, chlorophyll a; Chlb, chlorophyll b
