Mediation of a GDSL esterase/lipase in carotenoid esterification in tritordeum suggests a common mechanism of carotenoid esterification in Triticeae

Abstract

Los carotenoides son responsables de muchos de los colores entre el amarillo y el rojo de frutas, verduras y flores. Tienen funciones esenciales en la recolección de luz, la protección contra el exceso de energía lumínica y el daño oxidativo. El consumo de carotenoides se ha asociado con un menor riesgo de desarrollar algunas enfermedades y cánceres, pero los humanos no somos capaces de sintetizarlos, por lo que su suministro depende de la dieta. El tritórdeo (×Tritordeum martinii A. Pujadas), anfiploide derivado del cruce entre Hordeum chilense Roem. et Schultz. y trigo duro, tiene un alto contenido de carotenoides en grano. Además, gran parte de esos carotenoides se encuentran esterificados con ácidos grasos, lo que incrementa su estabilidad durante el almacenamiento y su capacidad de acumulación en las células vegetales. Trabajos previos del grupo habían localizado el gen de esterificación en el cromosoma 7 de H. chilense y habían identificado genes candidatos para el control de este carácter en trigo harinero. El objetivo es identificar el gen responsable de la esterificación de carotenoides en H. chilense mediante una estrategia de genes candidatos.
