Light harvesting capacity

One common feature in these mutants is the smaller photosynthetic unit size, as measured both by the Chl/P700 and Chl/Q ratios (Table 2). The important common feature, however, is the elevated PSII/PSI ratio in the mutants (Table 2). Since the mutation reduced primarily the light-harvesting capacity of PSII, elevated PSIl/PSI ratios may be thought of as a response of the plant in restoring the... 

In older low light plants, more light-harvesting capacity was available compared with photosystem II core complex (Table 1),...

In this photochemistry, the formation of the radical anion C02 has been demonstrated to be the key issue. The photomaterial used (ZnS) has the correct band gap, although Ru enhances the light harvesting capacity and drives the carboxylation reaction under sunlight irradiation.
