Expression of the maize proteinase inhibitor (mpi) gene in rice plants enhances resistance against the striped stem borer (Chilo suppressalis): effects on larval growth and insect gut proteinases

Abstract: SummaryThe maize proteinase inhibitor ( mpi ) gene was introduced into two elite japonica rice

“…Although the level of StPin1A in the hemizygous cotton plants was ≈1,000-fold lower than NaPI the presence of StPin1A still improved protection against insects in field trials. Combinations of PIs that target different classes of digestive proteases have shown promising results in planta (34,35), but individual inhibitors also have been reported to improve plant resistance to insects (36,37).…”

“…As plantas podem usar os inibidores de proteases como defesa direta contra os insetos, constitutiva ou induzida, inibindo as enzimas proteásicas nos intestinos de suas pragas (CARLINI e GROSSI-DE-SÁ, 2002;LAWRENCE e KOUNDAL, 2002). Assim, a inibição de proteases irá diminuir a biodisponibilidade de aminoácidos para a síntese de proteínas necessárias ao crescimento e desenvolvimento do inseto, acarretando, dessa forma, sua morte (HILDER et al, 1987;RYAN, 1990;VILA et al, 2005). Pilon et al (2006) verificaram que lagartas alimentadas com uma dieta contendo inibidores de proteases tiveram desenvolvimento reduzido em relação às lagartas alimentadas com a mesma dieta sem o inibidor.…”

“…Ovaj odgovor može ukazivati na adaptaciju na hranu koja je deficitarna u nekim esencijalnim nutrijentima i/ili sadrži štetne količine drugih (Coudron & Kim, 2004). Pokazan je veliki diverzitet i različita ekspresija gena za aminopeptidaze lepidoptera zavisno od prisustva različitih proteaznih inhibitora biljaka (Vila et al, 2005;Angelucci et al, 2008;Zhang et al, 2009;Crava et al, 2010). Mada je poznavanje nutrigenomike insekata još uvek nepotpuno, jasno je da je odgovor insekatskog genoma ima sposobnost finog podešavanja u odgovoru na dijetu (Yocum et al, 2006).…”

“…Pokazan je veliki diverzitet insekatskih aminopeptidaza u odgovoru na ishranu različitim povoljnim i nepovoljnim biljkama domaćinima, kao i različita ekspresija gena u odgovoru na proteazne inhibitore (Angellucci et al, 2008;Crava et al, 2010;Zhang et al, 2009). Kod Helicoverpa armigera i Cillio suppressalis pokazano je značajno povećanje aktivnosti aminopeptidaza na nepovoljnim biljkama domaćinima i smanjenje aktivnosti serinskih proteaza (tripsina i himotripsina), što može omogućiti izbegavanje toksičnih efekata usled nutritivnog disbalansa i regulaciju nivoa enzima u zavisnosti od sastava dijete (Vila et al, 2005;.…”
