Figure 6.

Effect of NO on the chlorotic phenotype of the ys1 and ys3 maize mutants. The ys1 and ys3 mutants were grown on vermiculite and watered with nutrient solution containing 100 μm Fe(III)-EDTA in the presence or the absence of 100 μm SNP. Representative photographs and chlorophyll content of the fourth leaves from 20-d-old ys1 (A) and ys3 (B) maize plants, either treated with SNP or untreated (control) are shown. Bar = 1 cm. Mean values and sds were calculated from four independent treatments.
