Combinations of genotypes and growth conditions used to obtain the five subdata sets

Subdata set	Genotype	Growth mediuma		Phenotypes
		Primary	Secondary
#1	WT	A	B	No apparent Anths
#2	WT	A	Cb	Accumulate Anths
#3	ch1-3	A	B	Chl b-deficient mutant, no apparent Anths
#4	ch1-3	A	Cb	Chl b-deficient mutant, accumulate Anths
#5	tt4	A	B	Anth-deficient mutant

Plants germinated on the primary medium were transplanted on day 8 to the secondary medium. They were grown for another 6–10 d before being subjected to hyperspectral reflectance imaging and chemical pigment analysis. WT, wild type.

^aCompositions of growth media indicated by each symbol are as follows: A, 1× MS (0/1× NH₄NO₃, 1× KH₂PO₄), 1% (w/v) sucrose; B, 1× MS (0/1/2× NH₄NO₃, 1×KH₂PO₄), 0/1/5 μM norflurazon; C, 1× MS (0/1/2× NH₄NO₃, 10⁻³× KH₂PO₄). 1× concentrations for NH₄NO₃ and KH₂PO₄ are 20.6 and 1.25 mM, respectively. Nutrient concentrations regarded as ‘normal’ are indicated in bold.

^bSome of the plants were wounded in root tissues after being transplanted to the secondary medium.
