Comparison of the host range and physical properties of Eola rasp leaf, tobacco ringspot and tomato ringspot viruses

Creator:: Liu, Kang-chien
Abstract:: Eola rasp leaf of cherry was first described by Milbrath and Reynolds in Oregon in 1961. Dr. Cadman of the Scottish Horticultural Research Institute suggested that this disease was incited by a strain of tomato ringspot virus (TomRSV), but since then controversial results with some isolates of EoIa rasp leaf...

Development of in vitro lily scale budlets as related to virus elimination

Creator:: Ruttum, Joanne C.
Abstract:: Lily hybrids vary in their ability to produce virus-free (VF) bulblets when grown from virus-infected scales in tissue culture. Asiatic hybrids typically produce a higher percentage of in vitro VF scale bulblets than do Lilium longiflorum cultivars. Three hypotheses concerning the cause of this variation are tested on five lily...

Studies on viruses isolated from roses with rose mosaic symptoms

Creator:: Watson, Thomas Ray
Abstract:: Previous work on the rose mosaic virus has produced uncertainty concerning the identity and properties of this virus. This work was undertaken to help establish the true identity of the virus and to determine some of its properties. A mechanically transmissible virus associated with rose mosaic virus disease of Rosa...

Amino acids in tissues from healthy and crown gall infected Kalanchoe pinnata

Creator:: Harris, Raymond Gene
Abstract:: Crown gall infected and healthy Kalanchoe pinnata (Lam.) Persoon plants were analyzed for soluble amino acids. Specifically the amino acids in young leaf, mature leaf, stem, root, and gall tissues were quantitatively measured. The plants were inoculated with the bacterium, Agrobacterium tumefaciens (Smith and Townsend) Conn., on one side of...

Light and electron microscopy of chloroplasts in Equisteum gametophytes

Creator:: Hook, Patricia Waynette, 1941-
Abstract:: Spores of Equisetum were germinated and the resulting gametophytes grown to maturity in standard microcultures. Light and electron microscope observations were made of the chloroplasts within the gametophytes. These chloroplasts were found to be oval to dumb-bell shaped organelles possessing organized grana. By means of time-lapse movies they were shown...

Ultrastructure of dormant and germinating conidia of Aspergillus nidulans

Creator:: Florance, E. R.
Abstract:: The cell wall of dry, dormant conidia of Aspergillus nidulans is three-layered. The wall of hydrated conidia is five-layered and the germ tube wall is continuous with the innermost layer. The outermost layer consists of rodlets measuring 10 nm in diameter. Mitochondria and endoplasmic reticulum increase in number and amount,...

Studies on the vesicular-arbuscular mycorrhizae of Easter lily in the Pacific Northwest

Creator:: Ames, Robert Norman
Abstract:: A study was conducted to characterize the vesicular-arbuscular (VA) mycorrhizal fungi of commercially grown Easter lily. Monthly field soil and root samples were collected from March through September, 1975, from five fields in the coastal area of southern Oregon and northern California. Soil sievings were inoculated onto clover, onion and...

Potato virus X : detection and inter-relationship with Verticillium dahliae and Colletotrichum atramentarium

Creator:: Goodell, Jody Jellison
Abstract:: Preliminary studies were run to determine the sensitivity and reliability of enzyme-linked immunosorbent assay (ELISA) for the detection of potato virus X (PVX). ELISA was found to be capable of detecting PVX in tobacco at a 1:3333 sample dilution. The reliability of ELISA for the detection of PVX in potato...

Purification and partial characterization of a virus associated with korogwe leaf spot disease of sisal

Creator:: Mpunami, Anatolia
Abstract:: Sisal Wave sisalana Perrine), one of Tanzania's main cashcrops, is severely affected by korogwe leaf spot disease (KLS).Infected plants show chocolate brown, concentric, scablike eruptions on both surfaces of mature leaves, and produce stained, low-quality fiber. A flexuous, rod-shaped virus was isolated from KLS-infected sisal leaves and studied at Oregon...
