mRNA relative accumulation of genes putatively involved in phenylpropanoid metabolism in elicited citrus fruits. The expression level was determined by Northern blot (●) or microarray (□) hybridizations. In general, a reference value of 1.0 was assigned to the nontreated flavedo, except for COMT1 and SAD genes as a result of a lack of expression in nontreated flavedo. Values from microarray hybridizations represent the average of three biological replicates ± SD. NT, nontreated fruits; I1, fruits infected with Penicillium digitatum during 1 day; IC, infected and cured fruits at 4, 5 and 7 days after the beginning of the experiment.
