Stability of Southern Bean Mosaic and Carnation Mottle Viruses during the Preservation by Freeze-drying
The infectivity of purified southern bean mosaic virus (SBMV) in 10mM sodium phosphate buffer, pH 7.0, decreased to 11% after freeze-drying. Such partially swollen virions were found to be markedly susceptible to RNase and sodium dodecyl sulfate (SDS). However, in the preparations supplemented with 0.5% lysine prior to freeze-drying the conformational changes of the virions were suppressed and ...
متن کاملImmunological classification of poliomyelitis viruses isolated in Japan.
Poliomyelitis viruses have been immunologically grouped into three types, Brunhilde, Leon and Lansing. Although much of effort has been devoted to isolate poliomyelitis virus in Japan1-2), little is revealed concerning the immunological property of the strains isolated3). After World War II, the existence of poliomyelitis virus •gLansing•h strain in Japan was suspected from the results obtained...
متن کاملRole of cytokinins in carnation flower senescence.
Stem and leaf tissues of carnation (Dianthus caryophyllus) plants appear to contain a natural antisenescence factor since removal of most of these tissues from cut carnation flowers hastened their senescence. However, kinetin (5-10 mug/ml) significantly delayed senescence of flowers with stem and leaf tissues removed. In addition, the life span of cut flowers with intact (30-cm) stems was incre...

Comparison o f sensitivity to exogenous ethylene and of ethylene binding. Scientia Hortic., 48:109-116. Flowers o f the 'Sandra' and "Chinera" cultivars o f carnation (Dianthus caryophyllus L. ) last about twice as long ( 14 days) as those o f 'Whi te Sim' cultivar (7 ...
متن کاملRole of the Ovary in Carnation Senescence
Mot, Y., Reid, M.S. and Kofranek, A.M., 1980. Role of the ovary in carnation senescence. Scientia Hortic., 13: 377--383. Ovary growth in carnation flowers was inhibited by pre-treatments with silver thiosulfate which retarded petal senescence. Although the start of ovary growth preceded visible wilting of untreated flowers, the ovary does not appear to control carnation senescence. Its removal ...
