Fusarium culture filtrates induce THI2.1p:uidA. THI2.1p:uidA is induced by jasmonates in meristems and the first true leaves of young seedlings and expresses β‐glucuronidase (GUS), which hydrolyses the indigogenic substrate 5‐bromo‐4‐chloro‐3‐indoxyl‐β‐d‐glucuronic acid (X‐Gluc) (Vignutelli et al., 1998). GUS activity in seedlings of THI2.1p:uidA (left), allene oxide synthase (aos) THI2.1p:uidA (middle) and aos (right) is stained blue by X‐Gluc 1 day after treatment with culture filtrates of Fusarium strains, F. oxysporum f. sp. matthioli (FOM) race 2, F. oxysporum f. sp. conglutinans (FOC) race 1, F. oxysporum f. sp. raphani (FOR), F. oxysporum f. sp. tulipae (FOT), F. oxysporum f. sp. lycopersici (FOL) race 2 and F. graminearum (FG) or methyl jasmonate (MeJA). Results with FOL race 2 and race 3 (not shown) were similar.
