Abstract

Patente de Invenção: <B>"MUTANTES ESTáVEIS AO CALOR DE ENZIMAS DE BIOSSìNTESE DE AMIDO"<D>. A presente invenção diz respeito a novas moléculas de polinucleotídeos mutantes que codificam enzimas que têm aumentada estabilidade térmica. Estes polinucleotídeos, quando expressos em vegetais, resultam em aumentado rendimento em plantas cultivadas sob condições de tensão térmica. As moléculas de polinucleotídeo da invenção em questão da invenção em questão codificam atividades de enzima sintase de amido solúvel (SSS) e priofosforilase de glicose ADP (AGP) de endosperma do milho. Também são contempladas pela presente invenção as plantas e tecidos vegetais multiplicados para conter, ou transformados com, os polinucleotídeos mutantes, e expressando os polipeptídeos codificados pelos polinucleotídeos. A invenção em questão também se refere a métodos para isolar polinucleotídeos e polipeptídeos contemplados dentro do âmbito da invenção. Também são fornecidos métodos para a aumentar a produção em plantas cultivadas sob condições de melhor tensão.
