Estudio acerca de la correlación entre el contenido de K+, actividad arginina y ornitina descarboxilasa, y niveles de aminóacidos libres, putrescina y nicotina en cultivos de callo de tabaco

Abstract

El presente trabajo se ha dividido en cinco partes fundamentales. En la Introducción figura la información bibliográfica disponible acerca de: a) Funciones del K+ significativas para el cultivo in vitro, b) Aminoácidos presentes en especies de Nicotiana y su control biosintético, c) Significación y metabolismo de poliaminas en plantas, d) Síntesis de nicotina en tabaco Burley 21, e) Formación de metabolitos secundarios en cultivo in vitro, y f) Organogénesis del cultivo de callo. En la Parte experimental, se describen con detalle las condiciones para el cultivo hidropónico de las plantas, el aislamiento y el cultivo de los explantes para la obtención del tejido de callo y el subcultivo del callo inicial sobre los dos medios de cultivo utilizados. En esta parte se describen también los métodos seguidos para el estudio del crecimiento y organogénesis de los tejidos de callo y para la determinación cuantitativa en ellos de K+, aminoácidos libres, putrescina, proteina soluble, actividades enzimáticas (ARG, ADC y ODC) y nicotina, y para la separación de la fracción proteica soluble por PAGE-SDS. En las restantes partes del trabajo, se describen los resultados, expresados en forma de tablas y figuras, se hace una amplia y detallada discusión de los mismos, y se ofrece un resumen de las principales conclusiones.
