We investigated cpDNA sequence and nuclear microsatellite variation among populations of the wild daffodil Narcissus triandrus to examine the role of historical vs. contemporary forces in shaping population structure, morphological differentiation and sexual-system evolution. This wide-ranging heterostylous species of the Iberian Peninsula is largely composed of two allopatric varieties (vars. ...

A one-step RT-PCR procedure was developed for specific detection of Narcissus latent virus (NLV) isolates. Following alignment of RNA sequences of three NLV isolates, the conserved sequence fragments were identified in viral polyprotein gene and 3’UTR region. Based on those fragments, a forward NLs1 and two reverse: NLa1 and NLSCPR2 primers were designed. Primer pairs NLs1-NLa1 and NLs1NLSCPR2 ...

Galanthamine, an acetylcholinesterase inhibitor marketed as a hydrobromide salt (Razadyne®, Reminyl®) for the treatment of Alzheimer's disease (AD), is obtained from Amaryllidaceae plants, especially those belonging to the genera Leucojum, Narcissus, Lycoris and Ungernia. The growing demand for galanthamine has prompted searches for new sources of this compound, as well as other bioactive alkal...
