abstract = {The photosynthetic, optical, and morphological
characteristics of a chlorophyll‐deficient
(Chl‐deficient) “yellow” soybean mutant (MinnGold)
were examined in comparison with 2 green varieties (MN0095
and Eiko). Despite the large difference in Chl content,
similar leaf photosynthesis rates were maintained in the
Chl‐deficient mutant by offsetting the reduced absorption
of red photons by a small increase in photochemical
efficiency and lower non‐photochemical quenching. When
grown in the field, at full canopy cover, the mutants
reflected a significantly larger proportion of incoming
shortwave radiation, but the total canopy light absorption
was only slightly reduced, most likely due to a deeper
penetration of light into the canopy space. As a
consequence, canopy‐scale gross primary production and
ecosystem respiration were comparable between the
Chl‐deficient mutant and the green variety. However, total
biomass production was lower in the mutant, which indicates
that processes other than steady state photosynthesis caused
a reduction in biomass accumulation over time. Analysis of
non‐photochemical quenching relaxation and gas exchange in
Chl‐deficient and green leaves after transitions from high
to low light conditions suggested that dynamic
photosynthesis might be responsible for the reduced biomass
production in the Chl‐deficient mutant under field
conditions.},
