a Changes in Fv/Fm over time in leaves following infiltration of SGRL, SGR or Empty Vector constructs in comparison to non-infiltrated areas, maintained in ‘light’ or ‘dark’ conditions. b Phenotype of leaves showing effects of transiently expressed constructs (as in a), under ‘light’ (left) or ‘dark’ (right) conditions 144 h after infiltration c Chlorophyll concentration (a, b and total) of leaf areas following transient expression (see a) for 140 h. Pairwise t tests indicated significant differences in chlorophyll concentration between light- and dark-incubated samples (*p < 0.05, **p < 0.01) within the constructs and controls tested, as indicated by brackets
