Resumen
Descripción
An experiment was conducted in order to study enzymes related to defense and stress mechanisms under controlled conditions, following dynamics of induction of PO and PPO in tomato plants var. Amalia using four species of mycorrhizal-arbuscular fungus (Glomus clarum, Glomus fasciculatum, Glomus claroideum and Acaulospora scrobiculata), and the expression of these enzymes was determined. These enzymes are induced in a differential way in time as much as in magnitude. Mycorrhizal specific isoforms for some of these species were observed.
