Many secondary plant compounds are synthesized in response to stressed growing conditions. We tested the feasibility of exploiting this feature in a novel strategy for the commercial production of the plant alkaloid galanthamine. Experimental lines of Narcissus pseudonarcissus were established under marginal upland permanent pasture at four different sites. Over 80% of bulbs successfully establ...

Narcissus tazetta var. chinensis M.Roem. (Chinese Narcissus) is a traditional and famous flower in China, its corona shows transition from green to yellow with the opening of flowers, which great ornamental value. To investigate molecular mechanism color-forming Chinese Narcissus, this study, MYB gene was screened transcriptome by bioinformatics analysis methods, named NtMYB9. The expression le...

The protein complement of chloroplasts, prochromoplasts, chromoplasts, and mitochondria of the daffodil (Narcissus pseudonarcissus) has been investigated comparatively by gel electro­ phoresis. Mitochondria do not share common proteins with plastids. On the other hand, there is a broad overlap of the protein complement of the three plastid types investigated, in spite of their different fine st...

Negative frequency-dependent selection is a major selective force maintaining sexual polymorphisms. However, empirical demonstrations of frequency-dependent reproductive success are rare, particularly in plants. We investigate this problem by manipulating the frequencies of style morphs in a natural population of Narcissus assoanus, a self-incompatible herb with style-length dimorphism and intr...
