Sentence examples for PSII quantum yield from inspiring English sources

For comparison with σPSII, and to facilitate future modelling efforts, we chose to estimate an effective target cross section for PSII photoinactivation (σi, nm2) by plotting the exponential decay of the PSII quantum yield FV/FM in the absence of repair versus the cumulative photon dose nm−2 (see Supplementary Data S1 and Figure S1 for justification).

The maximum PSII quantum yield was calculated as the ratio of variable to maximum fluorescence, Fv/Fm = (Fm Fo)/Fm.

Three variables maximum PSII quantum yield, Fv/Fm, maximum of relative electron transport rate rETRmax and photosynthesis-saturating irradiance Ek were calculated from RLCs (Fig. 4a c).

In the presence of actinic illumination, the current fluorescence yield (Ft = F), and the maximum fluorescence (Fm′) at the steady state, were determined, from which the effective PSII quantum yield, ΔF/Fm′ [(Fm′ − F /Fm′)] and ETR (PPFD × ΔF/Fm′ × 0.5 × 0.84) could be calculated.

The maximal PSII quantum yield was calculated as Fv/ Fm.

JS carried out the PSII quantum yield assays and helped draft the manuscript.

The resistant plants were characterized by lower PSII quantum yields at low temperature, combined with much higher energy flux for energy dissipation from the PSII reaction center.

However, the maximal PSII quantum yields (0.58 for apr1 and 0.66 for CC-425) and protein levels examined by Western blot analyses did not differ significantly from the wild type (Table 2, Figure 3).

Kitao et al. [ 9] suggested that excess Mn in white birch leaves affected the activities of the CO2 reduction cycle rather than the potential efficiency of photochemistry (Fv/Fm), leading to an increase in QA reduction state and thermal energy dissipation, and a decrease in photosystem II (PSII) quantum efficiency (quantum yield of PSII).

At each irradiance intensity, the actual (or effective) photosystem II (PSII) photochemical quantum yield in the light-adapted state, designated as YII was calculated as (Fm′ F′)/Fm′; it represents actual operational ability of photosynthesizing cells to convert light power into chemical energy.

The second parameter was used to isolate strains with either improved or unaltered PSII maximum quantum yield compared with WT.
