yield of light-induced nonphotochemical quenching Y (NPQ) and quantum yield of nonregulated energy dissipation Y (NO) ( Kramer et al., 2004 ). Although ΦII was lower in hy than those in WT, Y (NPQ) was much higher than WT ( Table 2 ). Table 2

quenching (qP), and nonphotochemical quenching (NPQ), were measured using a chlorophyll fluorescence imager (CF Imager; Techologica, Essex, UK). All fluorescence measurements were performed five times following the first NPs treatment, once every 10 d. The

photosynthetic system II (PSII) ( Huner et al., 1998 ; Lichtenthaler et al., 2005 ): the maximal quantum yield ( F v / F m ) = ( F m − F o )/ F m ; the effective quantum yield (Φ PSII ) = ( F m ′ − F s )/ F m ′; nonphotochemical quenching (qN) = ( F m − F m

harvesters of photons. These energized compounds and the processes they drive (photosynthesis, nonphotochemical quenching) affect metabolism and therefore develop metabolic product states that are sensed and used as information within the cell. Retrograde

nonphotochemical quenching (NPQ) of chlorophyll fluorescence], which possibly limits the formation of chlorophyll triplets and prevents ROS from being produced ( Demmig-Adams and Adams, 1992 ). Lutein and β-carotene are also key components of the light
