A Carnation ringspot virus (CRSV) variant (1.26) was identified that accumulates virions but is incapable of forming a systemic infection. The 1.26 capsid protein gene possesses a Ser-->Pro mutation at amino acid 282. Conversion of 1.26 amino acid 282 to Ser restored systemic infection, while the reciprocal mutation in wild-type CRSV abolished systemic infection. Similar mutations introduced in...

The lipid microviscosity of microsomal membranes from senescing cut carnation (Dianthus caryophyllus L. cv. White Sim) flowers rises with advancing senescence. The increase in membrane microviscosity is initiated within 3 to 4 days of cutting the flowers and coincides temporaDly with petal-inroDling denoting the climacteric-like rise in ethylene production. Treatment of young cut flowers with a...

Salmon are keystone species to multiple environments and are heavily relied upon by many different organisms. This study compares the populations of rearing Coho salmon fry (Oncorhynchus kisutch) at pre-established sampling sections of Carnation Creek. This population data was collected during the summer as part of the more extensive Carnation Creek Watershed study, which is the longest continu...
