Variation in non-photochemical quenching (NPQ) in natural Arabidopsis accessions, a PsbS mutant (npq4) and a PsbS overexpresser (oePsbS). A In the field and B in a growth chamber. C Correlation (scatter plot) between NPQ levels for the accessions grown in growth chambers and in the field. Data represent means ± SE for leaves from at least six plants grown in two batches.
