Produção in vitro de enzimas extracelulares por fungos e sua relação com os sintomas descritos em planta hospedeira

Abstract: RESUMOOs fungos fitopatogênicos habitantes de solo causam perdas econômicas em muitas culturas e são difíceis de serem controlados. Esses fungos podem ser agrupados pelos sintomas comuns que causam nas plantas, bem como pelas enzimas extracelulares que podem produzir. O objetivo do trabalho foi verificar a produção in vitro de enzimas extracelulares por fungos de solo e tentar relacionar essas enzimas com os sintomas que cada fungo causa em planta hospedeira. O ensaio foi delineado em esquema inteiramente casu… Show more

“…These fungi cause major economic losses in agriculture, due to its defense structure, namely sclerotia which survive in the soil for years, thereby, making this pathogen difficult to control (Madhuri & Gayathri, 2014;Guerra et al, 2015;Sneha et al, 2016). A. rolfsii produces an extracellular enzyme, namely cellobiose dehydrogenase (CDH) used to penetrate the host plant, while S. rolfsii also produce six extracellular enzymes, including amylase, carboxymethyl cellulase, lipase, laccase, catalase and gelatinase which are used to infect plant tissues (Chaurasia et al, 2015;Elias et al, 2015;Sennoi et al, 2021). The macroscopic and microscopic morphology of the two species are the same and difficult to distinguish, hence, molecular identification is needed to differentiate between the species (Paul et al, 2017).…”
