    Notes: Abstract Chitinases were studied in an endomycorrhiza-resistant mutant and wild type pea (Pisum sativum L. cv. Frisson) in order to characterize plant hydrolases specific to pathogenic (Aphanomyces euteiches andChalara elegans) or mycorrhizal (Glomus mosseae) root interactions. Stimulation of constitutive and induction of new chitinase activities was detected by native PAGE for acidic proteins in both pea genotypes inoculated with pathogenic fungi. In contrast, a different additional chitinase isoform was induced inG. mosseae-colonized roots. This isoform was also not elicited in chemically-stressed roots, confirming its mycorrhiza-specificity. Investigations of basic chitinase andβ-1,3-glucanase activities provided further evidence for differential pea responses during pathogenic and symbiotic interactions.

    Plant hydrolytic enzymes (chitinases and β-1,3-glucanases) in root reactions to pathogenic and symbiotic microorganisms (1996)
    Springer
    Plant and soil 185 (1996), S. 211-221

    Notes: Abstract Within the last decade, a great deal of attention has been devoted to the role of chitinases and β-1,3-glucanases in plant/microbe interactions. While there is strong evidence that these hydrolases are antifungal proteins, there are also recent indications of roles in both plant morphogenesis and plant/microbe signal perception. This paper reviews recent findings pertinent to root/microbe interactions, and discusses the nature and significance of specific hydrolase isoforms in symbioses with arbuscular mycorrhizal (AM) fungi.
