Narcissus: Visualising Information

It is becoming increasingly important that support is provided for users who are dealing with complex information spaces. The need is driven by the growing number of domains where there is a requirement for users to understand, navigate and manipulate large sets of computer based data; by the increasing size and complexity of this information and by the pressures to use this information efficie...

Infection of Narcissus Roots by Aphelenchoides subtenuis.

The widespread destruction of commercially grown bulbs of Narcissus tazetta papyraceus (Paper White) has been reported in Israel. This phenomenon is usually characterized by a premature yellowing of the foliage, accompanied by root rot and dark, sunken basal plates. This study confirmed thatAphelenchoides subtenuis is the main cause of the basal plate disease of Narcissus. In contrast to other ...

Two new alkaloids from Narcissus serotinus L.

The Amaryllidaceae family is well known for the presence of an exclusive group of alkaloids with a wide range of biological activities. Narcissus serotinus L. is a plant belonging to this family and its geographical distribution is mainly located along the Mediterranean coast. In the present work, specimens collected near Casablanca (Morocco) were used to study the alkaloid content of this spec...

Nucleotide sequence of narcissus mosaic virus RNA.

The nucleotide sequence of the genomic RNA of narcissus mosaic virus (NMV) was deduced from a set of cDNA clones and by direct sequencing of RNA. The genome, with a length of 6955 nucleotides [excluding the 3'poly(A) tail], contains six open reading frames (ORFs) with the capacity to code for polypeptides of more than 10K, with Mr values of 186284, 25845, 13998, 11059, 26097 and 10519. The firs...
