Complete sequence of the citrus tristeza virus RNA genome.
Phylogenetic analysis of the three replication-associated domains, MT, HEL, and RdRp, indicates that CTV and BYV form a separate closterovirus lineage within the alpha-like supergroup of positive-strand RNA viruses.

The relationship of total and methyl mercury concentrations in fish to those of sediments from corresponding locations was fish-species dependent, in addition to several abiotic factors, and among fish species analyzed, hardhead cat fish, gafftopsail catfish, and sand seatrout contained the highest concentrations of mercury.
The Continuous Challenge of Citrus Tristeza Virus Control
Detection of 'Candidatus Liberibacter asiaticus' in Diaphorina citri and its importance in the management of citrus huanglongbing in Florida.
The study suggests that discount garden centers and retail nurseries may have played a significant role in the widespread distribution of psyllids and plants carrying HLB pathogens in Florida.
Organization of the 3'-terminal half of beet yellow stunt virus genome and implications for the evolution of closteroviruses.
The double-stranded RNA "replicative form" of the BYSV was demonstrated to have a nontemplate G residue at the 3' terminus of the (+) strand, which suggests that these three viruses might represent three distinct but probably close stages in the closterovirus evolution.
Defective RNA molecules associated with citrus tristeza virus.
Northern hybridization analysis demonstrated that this 2.4-kb defective RNA is an abundant species among the other CTV-specific ss- and ds-RNAs in infected plants.
Fate of petroleum hydrocarbons taken up from food and water by the blue crab Callinectes sapidus
The hepatopancreas contained highly polar hydrocarbon metabolites, including diHydroxy-compounds and their conjugates, while blood contained both monohydroxy-and dihydroxy- Compounds, and no evidence was found of storage of hydrocarbons by any of the crab tissues.
Lipid composition of the copepod Calanus hyperboreas from the Arctic Ocean. Changes with depth and season

Gas-liquid chromatographic studies of the lipids showed that both the alcohols and fatty acids of the wax esters were highly variable with season and depth, whereas the phospholipid fatty acids were not affected by changes in these parameters.
Multiple species of defective RNAs in plants infected with citrus tristeza virus.
Northern blot hybridizations of dsRNAs extracted from serial passages of the Israeli VT isolate (CTV-VT) and from different plants infected with a single source of inoculum showed considerable variation both in the presence and in the relative abundance of the defective RNA (D-RNA) bands.
