Evidence for an evolutionary hourglass pattern in herbivore-induced transcriptomic responses

Kenetics of herbivore induced responses in Nicotiana attenuata leaves Gene expression in leaves of Nicotiana attenuata wild type plants were measured at different time points (0.5 h, 1 h, 2 h, 5 h, 6 h, 11 h, 13 h) after elicitation with oral secretions (OS) of Manduca sexta larvae. Three independent experiments were performed for control plants and plants treated with OS.
