Identification of membrane proteins of human blood platelets with a hydrophobic photolabel
A photoactivable glycolipid probe, 12-(4-azido-2-nitrophenoxy)stearoyl[1-14C]glucosamine, was used to label proteins and lipids of platelet membranes. The proteins were analyzed by two-dimensional high-resolution ...
Sunlands irrigation scheme headworks upgrading, hydraulics of the water distribution system.
(Institution of Engineers, 1984-09-01)
High salinity levels on the River Murray have caused damage to irrigated crops due to salt toxicity. The toxic effects can be mitigated by irrigating at night only. On Sunlands irrigation scheme (700 hectares) the pumping ...
Labeling of phospholipids in vesicles and human-erythrocytes by photoactivable fatty-acid derivatives
The photoactivable glycolipid probes, 2-(4-azido-2-nitrophenoxy)palmitoyl[1-I4C]glucosamine (compound A) and 12-(4-azido-2-nitrophenoxy)stearoyl[1-14C]glucosamine (compound B) were synthesized essentially as described ...
Plasmids containing one inverted repeat of Tn21 can fuse with other plasmids in the presence of Tn21 transposase
In the presence of the Tn21 transposase, plasmids that contain a single Tn21 inverted repeat sequence fuse efficiently with other plasmids. This reaction occurs in recA strains, is independent of the transposon-encoded ...
Negatively supercoiled DNA from plants infected with a single-stranded DNA virus
A method for isolating covalently closed circular double-stranded DNA from plants infected with the geminivirus, tomato golden mosaic virus, is described. Ethidium bromide titration showed this DNA to be negatively supercoiled ...
Effect of cellulose xanthate on splash dispersal of Pseudocercosporella herpotrichoides spores
Cellulose xanthate reduced dispersal of Pseudocercosporella herpotrichoides spores from wheat straw by simulated rain.
Production and pathogenicity to wheat of Pseudocercosporella herpotrichoides conidia
Weekly estimates of numbers of Pseudocercosporella herpotrichoides conidia on naturally infected wheat straw, made from February to July 1982, showed there were most conidia (8.1 × 106 per straw) in February and least (1.9 ...
Studies on mechanisms of splash dispersal of spores, using Pseudocercosporella herpotrichoides spores
Simulated raindrops, 4 or 5 mm in diameter, fell 13 m onto target water films, with Pseudocercosporella herpotrichoides spores incorporated into either drops or targets. Resulting splash droplets were collected on fixed ...
