Abstract
Los carotenoides son un grupo de pigmentos isoprenoides sintetizados por todos los
organismos fotosintéticos y algunas bacterias y hongos. Los animales y otros
organismos que no los producen in vivo deben incluirlos en su dieta ya que, por
ejemplo, son responsables de la coloración del plumaje y de algunas aves y precursores
de compuestos esenciales como la vitamina A. Además, su capacidad antioxidante y
sus aplicaciones nutraceúticas les hacen ser productos de una alta importancia
económica.
La manipulación genética de la microalga Chlamydomonas reinhardtii es la principal
herramienta en el que se basa este trabajo. Mediante la expresión de genes exógenos,
pretendemos incrementar el contenido en carotenoides y obtener un conocimiento más
profundo de las enzimas involucradas en esta ruta y su regulación in vivo. Además,
diferentes condiciones de estrés ambiental han sido utilizadas para clarificar la
respuesta funcional de esta ruta en esta clorofita.
Carotenoids are a wide group of lipophylic isoprenoid compounds synthesised by all photosynthetic organisms and also by sorne non photosynthetic bacteria and fungi. This is the reason why animals and other organisms that do not synthesise them de novo must include them in their diet to acquire their characteristic colours or as precursors for essential compounds. Carotenoids have been described as indispensable in light collection and energy transmission during photosynthesis and their antioxidant capacity and applications in nutraceuticals andas feed additives make them be ofhigh economical valuable products. The genetic manipulation ofthe microalga Chlamydomonas reinhardtii is the principal tool on the basis ofthis work. By means ofthe exogenous gene expression, we expect to in crease the carotenoid content and obtain a deep understanding of the enzymes involved in the pathway and its in vivo regulation. Also, different environmental conditions have been used to clarify the functional response of the route in this microalga.
