“…Furthermore, the gelatinous matrix of egg masses of root-knot nematodes has been found to trigger production of proteolytic and chitinolytic enzyme by the fungus (Sharon et al, 2007;Golzari et al, 2011). Rajinikanth et al (2016) stated that chitinolytic enzyme chi18-5 of T. viride played a vital role in the induction of mycosis in the nematode eggs.…”

“…Dentre todas as enzimas produzidas por isolados de Trichoderma, as quitinases desempenham um importante papel no parasitismo de ovos de nematoides (RAJINIKANTH et al, 2016;SHARON et al, 2007;ZHANG et al, 2017)…”

“…demonstraram que na espécie T. harzianum os níveis de expressão dos genes chi18-5 (chit42) e chi18-12 (chit33), que codificam duas endoquitinases, aumentaram em poucas horas a partir do contato do fungo com os ovos dos nematoides. Assim, o fungo utiliza esse tipo de enzima para romper a casca do ovo do nematoide e completar o parasitismo(RAJINIKANTH et al, 2016).A porcentagem de parasitismo pode ser altamente variável dependo da cepa utilizada nos testes.Ferreira et al (2008) observaram taxas de parasitismo de ovos de M. exigua entre 33 e 53% quando utilizaram diferentes isolados de Trichoderma em teste in vitro. Nos estudos conduzidos por Eapen, Beena e Ramana (2005), a porcentagem de parasitismo de ovos de M. incognita por Trichoderma spp., variou entre 10 e 24%.…”
