Resumen

Antibodies raised against Trichoderma harzianum conidia prevented accumulation of Phenylalanine ammonia-lyase PAL, E.C. 4.3.1.5. in Citrus. The observed effect of the antibodies is produced by a delay in the formation of the fungal germination tube. An increase of PAL activity of ca. 7 fold in C. limon and C sinensis seedlings, and of ca. 2 fold in C. paradisii seedlings was found, as an hypersensitive response to inoculation with T. harzianum conidia. This increase in activity was due to <> synthesis of the enzyme as demonstrated by the effect of protein-synthesis inhibitors and by immunotitration.Nota general
