From: Lactic acid induced defense responses in tobacco against Phytophthora nicotianae
Effect of exogenous 7 mM lactic acid pretreatment for 7 days on (A) H2O2 content, (B) protein content, (C) total phenolic content, (D) lignin content, (E) CAT activity, (F) POD activity, and (G) PAL activity in tobacco leaves after inoculation with P. nicotianae (P. nic). (DW + Mock) Sprayed with DW/mock inoculation; (DW + P. nic) Sprayed with DW/inoculated with P. nicotianae; (LA + Mock) Sprayed with lactic acid/mock inoculation; (LA + P.nic) Sprayed with lactic acid/inoculated with P. nicotianae. Data (means ± SE, n = 4) followed by different letters above the bars indicate significant differences (p < 0.05).
