Twenty mg of inoculum containing about 5000 spores was used to inoculate 15 day old Z. mauritiana seedlings using our previous method (Mathur & Vyas, 1995). The plants were grown in sterilized 20 cm diameter pots.…”

“…Increased PPO activity and a new PPO-isoform were detected in three species of Ziziphus inoculated with Glomus fasciculatum (Mathur and Vyas, 1995). Nevertheless, Pérez et al (2004) found increments in PPO activity at early colonization stages for tomato interaction with G. clarum and G. claroideum, but not with G. fasciculatum neither A. scrobiculata; whereas at late colonization stages only G. clarum and A. scrobiculata increased this activity.…”

In contrast, Fries et al (1996) and Pozo (1999) found only quantitative differences of root POX-isoenzyme patterns in the interactions corn-G. intraradices and tomato-G. mosseae.…”

Antioxidant system is involved in arbuscular mycorrhizal symbiosis, but its role during the colonization process is still poorly understood. To gain new insights into the role of antioxidant system during root colonization by arbuscular mycorrhizal fungi, the activities of key antioxidant enzymes were evaluated in tomato (Solanum lycopersicum L.) roots inoculated with six strains of different genera and species: two Glomus mosseae, Glomus cubense, Glomus intraradices, Glomus sp. and Acaulospora scrobiculata. Glomus cubense and A. scrobiculata strains reached the highest infectivity levels with maximum values of colonization frequency and intensity of 29-10.88% and 18-9.20%, respectively; G. mosseae strains showed an intermediate infectivity, both with 15% of colonization frequency and maximum intensities of 7.64-7.06%, respectively; while the infectivity levels of Glomus sp. and G. intraradices strains were the lowest with colonization frequency-13% and intensities-5.07 and 5.41, respectively. Some activity patterns of peroxidase, superoxide dismutase, and polyphenol oxidase enzymes were not specific for early or late colonization stages neither for the colonization level and type of strain. However, a unique superoxide dismutase-band presents at early colonization and the low level of guaiacolperoxidase activity at later stages presents in all inoculated roots indicate that these antioxidant responses are independent of colonization degree and strain. Taking together, our data suggest that alterations of the antioxidant enzyme activities are not general characteristics of the colonization process by arbuscular mycorrhizal fungi, probably having the key role on those responses the specific feature of each strain rather than colonization per se.

Mots c/es : peroxydases -reactions catalytiques -role physiologique.Abstract.-Peroxidases are heme proteins involved in the oxidization of a large variety of substrates, through the reaction with hydrogen peroxide. Plant peroxidases are class Ill peroxidases, according to nomenclature. Primary and tertiary structure, as well as principles of reactions catalyzed by such peroxidases are discussed. Class Ill peroxidases are involved in different physiological functions, such as cell wall metabolism, hormonal metabolism, responses to abiotic stresses, and plant-microorganisms interactions. Biotechnological applications are presented.
