Observations on chytridiaceous parasites of phanerogams
(Springer-Verlag, 1964-06)
A reexamination of Physoderma maculare Wallroth the type species of the genus, on Alisma , confirms Clinton's (1902) account of the production of an epibiotic stage from resting spore zoospores. The latter on mature host ...
The Thai variant and the distribution of alleles of 6-phosphogluconate dehydrogenase and the distribution of glucose 6-phosphate dehydrogenase deficiency in Thailand
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1968-11)
The samples were taken from 3185 subjects from ten provinces throughout Thailand. In 1577 males the frequency of glucose 6-phosphate dehydrogenase deficiency was 11.98%. In the far south the gene frequency was 2.83%; in ...
The production of superoxide anion radicals in the reaction of reduced flavins and flavoproteins with molecular oxygen
(Elsevier, 1969-09-10)
The generation of O2-- in the reaction of reduced flavins and several flavoproteins has been shown. This has been demonstrated by the ability to catalyse the aerobic reduction of cytochrome and the inhibition of this ...
Molecular localization of frog retinal receptor photopigment by electron microscopy and low-angle X-ray diffraction
(Elsevier, 1969-02-14)
Low-angle X-ray diffraction patterns were obtained from ordered ultracentrifugal pellets of wet receptor disk membranes which had been either treated with antirhodopsin serum, normal rabbit serum, serum albumin, or untreated ...
Synthesis and maturation of phage P22 DNA : I. Identification of intermediates
(Elsevier, 1968-06-28)
Two intermediates in the synthesis and maturation of phage P22 DNA have been identified by sedimentation of lysozyme-detergent lysates of induced lysogens or infected cells through sucrose density-gradients. Intermediate ...
Observations on chytridiaceous parasites of phanerogams
(Springer-Verlag, 1961-09)
Resting spores of the chytrid parasite of Claytonia virginica or “Spring Beauty”, Physoderma claytonianum var. sparrowii , were overwintered in plastic containers buried at the site of collection near Ann Arbor, Mich., ...
Structure of normal and contracted tail sheaths of T4 bacteriophage
(Elsevier, 1967-07-28)
The structural arrangement of protein subunits in extended and contracted tail sheaths of T4 bacteriophage has been studied by optical diffractometry of electron micrographs. The analysis of such diffraction patterns shows ...
Infrared method for determining circadian patterns of carbon dioxide release
(Springer-Verlag, 1969-06)
Using an infrared technique based on the continuous monitoring of a characteristic infrared absorption band, temporal variations in the circadian patterns of carbon dioxide release were examined in two species of noctuid ...
Chromosome number in the lizard genus Uta (family Iguanidae )
(Springer-Verlag, 1968-12)
A chromosome number of 34 (12 macro- and 22 microchromosomes) was found to be characteristic of the bone marrow in 47 animals including males from the species Uta antiquus , and both males and females from the following ...
