MAPK, mitogen‐activated protein kinase; ROS, reactive oxygen species. Please see text for expansion of gene abbreviations.

*↓, affected (reduced); =, not affected.

†Phase in which each response reaches maximal expression. Early, maximal response up to around 1 h; late 1 and late 2, maximal response around 3 h and at least 8 h, respectively.
