Figure 7: Temporal pattern of accumulation of salicylic acid in two-day old pearl millet seedlings harvested at 0, 3, 6, 9, 12, 24, 48 and 72 h with (inoculated) or without (uninoculated) Sclerospora graminicola inoculation.

Quantification of SA was done by wavelength scan identification of elicitation wavelength of 312 nm and an emission wavelength of 415 nm Resistant – Seedlings of downy mildew resistant cultivar, Chitosan-Seedlings treated with Chitosan, T. hamatum UOM 13-Seedlings treated with the endophyte T. hamatum UOM 13, Control: Seedlings of downy mildew susceptible cultivar. Data of enzyme activity are means ± SE of three different experiments. The values were the means of three replicates of three different experiments. Bars indicate standard errors; means with different superscripts are significantly different, as shown by Tukey’s HSD test (P = 0.05).
