Dynamic induction of some defense systems in the AMF-tomato (Lycopersicon esculentum Mill.) interaction var. Amalia. I. Induction of PR2, PR3 and phenyl alanine ammonialyase in tomato roots
Main Article Content
Abstract
biochemical mechanisms of plant defense in mycorrhizaltomato
interaction, levels of activation of local defense induced
by arbuscular-mycorrhizal fungi (AMF) were determined and
the time of these responses are sustained in tomato plants var.
�??Amalia�?�. Under semicontrolled conditions, four AMF were
studied: Glomus clarum, Glomus fasciculatum, Glomus
claroideum and Acaulospora scrobiculata; those species induce
PR2, PR3 and phenyl alanine ammonialyase differently
as in time and magnitude. G. fasciculatum and G. clarum were
the species which induce the highest levels of these enzymes.
