Esta Tesis estudia la regulación de la síntesis de carotenoides en el hongo Phycomyces blakesleeanus. El tipo silvestre del hongo produce casi exclusivamente β-caroteno, pero las cantidades acumuladas dependen de factores ambientales, como la luz, diversos productos químicos, la vecindad del sexo opuesto y las condiciones de cultivo.Se han...

Production of fl-carotene by wild-type Phycomyces blakesleeanus can be stimulated by light, chemicals, regulatory mutations, and sexual interaction between mycelia of opposite sex. Through genetic manipulations, we have isolated strains which have simultaneously and constitutively incorporated several of these stimulatory effects. In the dark...
