because respiration as well
as photosynthesis are metabolic pathways that produce chemical
energy (i.e.ATP and redox equivalents) tomeet cell energy
demands for growth and maintenance (Noguchi & Yoshida
2008). The reductions in A390 were linked to reductions in total
plant dry mass at the final stage as well as grain yield (Fig. 3).
Plant harvest index, the ratio of grain weight to total plant
weight, was similar between wild-type and transgenic plants
(Fig. 3). As a result, there was a strong positive correlation
between total plant dry mass and grain yield (Fig. 4).
