CYP11A1 and infection: Through five consecutive generations transgenic tobacco plants expressing heterologous sequence of the mammalian CYP11A1 cDNA have a distinct, clearly distinguishable phenotype characterized by the reduced period of vegetative development (early flowering and maturation of bolls), enlarged biomass and increased productivity (quantity and quality of seeds), and also greater resistance to biotic stresses: positive effect of CYP11A1 on resistance of transgenic tobacco plants to the infection by fungal phytopathogen Botrytis cinerea was for the first time detected.
