“…The reduced leaf damage observed in the resistant genotypes, could also be due to the decreased nutritive value of the plant parts that was reported to be increased by peroxidase activity (War et al, 2011a). Furthermore, increased formation of lignin, hinders the stylet penetration of the pest in the cell wall ( Whetten and Sederoff, 1995).…”

“…[4][5][6] Plants confront the herbivores both directly by affecting host plant preference or survival and reproductive success (direct defense), and indirectly through other species such as natural enemies of the insect pests (indirect defense). 1,7,8 Direct defenses are mediated by plant characteristics that affect the herbivore's biology such as mechanical protection on the surface of the plants (e.g., hairs, trichomes, thorns, spines, and thicker leaves) or production of toxic chemicals such as terpenoids, alkaloids, anthocyanins, phenols, and quinones) that either kill or retard the development of the herbivores.…”

“…1,12 Changes in defensive constituents of a plant on account of insect attack develop unpredictability in the plant environment for insect herbivores, which in turn, affects the fitness and behavior of the herbivores. 5,6,14 If induced response occurs very early, it is of great benefit to the plant, and reduces the subsequent herbivore and pathogen attack, besides improving overall fitness of the plant. 12 Plants with high variability in defensive chemicals exhibit a better defense compared with those with moderate variability.…”

“…Outras enzimas antioxidantes importantes incluem lipoxigenases, fenilalanina amônia liase, superóxido dismutase, entre outras. Indução de enzimas antioxidantes em plantas devido à herbivoria tem recebido atenção considerável nos últimos anos (HENG-MOSS et al, 2004;CHEN et al, 2009;RANI & JYOTHSNA, 2010;VANDENBORRE et al, 2011;WAR et al, 2011a;WAR et al, 2011b).…”

RESUMOMuitas plantas passam por mudanças bioquímicas significativas em resposta ao ataque de estressores bióticos, como patógenos ou insetos herbívoros. Ambos estressores bióticos quando atacam as plantas fazem com que estas respondam de forma rápida com uma "explosão oxidativa", que constituem na produção de espécies reativas de oxigênio (ERO), principalmente ânion superóxido (O 2•-) e peróxido de hidrogênio (H 2 O 2 ). O acúmulo destas substâncias nas células vegetais pode ser tóxico para ambos. Estas EROs acionam moléculas para a indução de genes de defesa e a polimerização de proteínas que compõe a parede celular, além de estimular a produção de enzimas antioxidativas ou de limpeza. Existe uma variedade destas enzimas que irão decompor as espécies reativas de oxigênio. Como por exemplo, temos superóxido dismutase (SOD), peroxidase (POX), catalase (CAT), polifenol oxidase (PPO), entre outras. Nesta revisão será abordado como a herbivoria e a patogenicidade desencadeiam uma explosão oxidativa ativando o sistema de defesa da planta com a ação das enzimas antioxidativas. PALAVRAS-CHAVE: catalase, peroxidase, estresse biótico, inseto, fungo. THE ROLE OF ANTIOXIDANT ENZYMES IN PLANT DEFENSE AGAINST HERBIVOROUS INSECTS AND PHYTOPATHOGENSABSTRACT Many plants suffer significant biochemical changes in response the attack of biotic stressors, such as phytopathogens or herbivorous insects. When any of these biotic stressors attack plants, this causes quick responses via an "oxidative burst", which constitutes the production of reactive oxygen species (ROS), particularly superoxide anion (O 2•-) and hydrogen peroxide (H 2 O 2 ). The accumulation of these substances in vegetal cells can be toxic to both the biotic stressors and plants. These ROS will trigger molecules for the induction of defense genes and polymerization of proteins that makes up the cell walls, as well as stimulate the production of antioxidant enzymes or scavenging. There are a variety of these enzymes that will decompose the reactive oxygen species; the superoxide dismutase (SOD), peroxidase (POX), catalase (CAT) and polyphenol oxidase (PPO) are some examples. This review will describe how herbivory and pathogenic triggers cause an oxidative burst stimulating the defense system of the plants with the actions of antioxidant enzymes.
