cytodifferentiation in the rosy mutant of drosophila melanogaster.in the rosy mutant of drosophila melanogaster, two types of autofluorescent cytoplasmic inclusions are found in the cells of the posterior region of the fatbody at the prepupal stage. bright yellow autofluorescent granules accumulating within larger inclusions clearly demarcate this area of the fatbody which also contains cobalt blue fluorescent globular material. such inclusions were not noted in the normal ore-r strain at this stage nor in the series of mutant strains examined other than the r ...196214492629

arsenates: effect on fecundity in some diptera.four species of adult diptera, rhagoletis pomonella (walsh), drosophila melanogaster mg., drosophila hydei sturt., and musca domestica l. showed varying degrees of reduced fecundity when sublethal doses of arsenic were included in their food. the possible influence of the frequent use of arsenicals on arthropod populations is discussed.196317829544
electron microscopic studies on the indirect flight muscles of drosophila melanogaster. ii. differentiation of myofibrils.the differentiation of the indirect flight muscles was studied in the various pupal stages of drosophila. fibrillar material originates in the young basophilic myoblasts in the form of short myofilamants distributed irregularly near the cell membranes. the filaments later become grouped into bundles (fibrils). certain "z bodies" appear to be important during this process. the "z bodies" may possibly be centriolar derivatives and are the precursors of the z bands. the first formed fibrils (having ...196313988340
electron microscopic studies on the indirect flight muscles of drosophila melanogaster. i. structure of the myofibrils.the myofibrils in drosophila have thick and thin types of myofilaments arranged in the hexagonal pattern described for calliphora by huxley and hanson (15). the thick filaments, along most of their length in the a band, seem to be binary in structure, consisting of a dense cortex and a lighter medulla. in the h zone, however, they show more uniform density; lateral projections (bridges) also appear to be absent in this region. the m band has a varying number of granules (probably of glycogen) di ...196313988339

an influence of maternal nutrition upon the gross chromosomal mutation frequency recovered from x-rayed sperm of drosophila melanogaster. 196313954141
an inducible enzyme system in the larval cells of drosophila melanogaster.an adaptive increase in tryptophan pyrrolase activity was obtained in the cell-free extracts of drosophila melanogaster larvae which were given a dietary supplement of l-tryptophan. this activity was detectable in the extracts prepared from larval fatbodies when these were isolated from the remaining body tissues, but the present methods did not reveal any activity in extracts from the latter. these experiments confirm previous observations on the cellular distribution of kynurenine after feedin ...196313974166
beta-alanine utilization of ebony and non-ebony drosophila melanogaster.carbon-14-labeled beta-alanine was injected into newly formed drosophila melanogaster female pupae. homozygous ebony deposited less c(14) in pupal sheaths, deposited more c(14) in adult body extracts and wings, and decarboxylated and oxidized beta-alanine to excrete c(14)o(2) faster than did non-ebony homozygotes. heterozygotes were intermediate in all these activities.196317757059
correlation between the number of scutellar and abdominal bristles in drosophila melanogaster. 196317248156
genetic control of cytodifferentiation.the cells of the anterior region of the larval fatbody of drosophila melanogaster accumulate kynurenine at the end of the third larval instar, whereas the cells of the posterior region are involved in pteridine metabolism. through a series of transplantation experiments it has been demonstrated that the anterior fat cells synthesize kynurenine. the mutant vermilion lacks kynurenine, and the anterior fat cells of this mutant strain lack the autofluorescence characteristic of kynurenine. when the ...196313974165

overlap of the birefringent component of adjacent a regions during the induced shortening of fibrils teased from drosophila muscle.fibrils from the indirect flight muscle of drosophila melanogaster which have been teased into a solution containing 0.1 m kcl, 2 mm edta, 4 mm mgcl(2), and 2.5 mm atp at ph 7.0 can be made to shorten to 10 per cent of their initial length by reducing the level of atp at a ph of about 8 or by briefly treating the fibrils with trypsin before lowering the level of atp. fibrils shortened in either of these ways, when dehydrated and immersed in nitrobenzene, display a strong positively birefringent ...196314069790

mutations: incidence in drosophila melanogaster reared on irradiated medium.an increase in the rate of mutation has been found in drosophila melanogaster reared on a basic medium that was irradiated with a sterilizing dose (150,000 rads) of cobalt-60 gamma rays. in muller-5 tests, sex-linked recessive lethals occurred only in the f(2) progenies of the male test flies obtained from breeding the parent flies on irradiated medium, while visible changes occurred in experimental cultures from both the control and irradiated media. the frequency of sex-linked recessive lethal ...196317781759

on the mechanism of some temperature effects on drosophila.the results of detailed kinetic studies on temperature adaptation and on crossvein deformation in drosophila melanogaster pupae are presented. a scheme which unifies most of these effects is offered, suggesting that the basic events are a series of changes in the tertiary structure of a protein. implications of the findings and the scheme are discussed with particular respect to temperature adaptation and to development.196314042997

factors affecting the intracellular synthesis of kynurenine.near the time of pupation, autofluorescent kynurenine globules appear in the cells in the anterior region of the fatbody of drosophila melanogaster. it has been reported previously that kynurenine synthesis may be induced in an additional group of fat cells by feeding the precursor tryptophan to drosophila larvae, and that this induction of kynurenine production viewed within the fat cells is correlated with an increase in tryptophan pyrrolase activity. in the present report, conditions are outl ...196414154493

toxic residues in soil 9 years after treatment with aldrin and heptachlor.in silt loam soil heavily infested with european wireworm, a single treatment with aldrin or hepta chlor prevented reinfestation for 9 years, even when the soil was under continuous cultivation. toxic residues were determined by bioassay with drosophila melanogaster meig. by gasliquid chromatographic analysis, the residues were found to be mainly dieldrin and heptachlor epoxide.196417772621

glucose-6-phosphate dehydrogenase in drosophila: x-linked electrophoretic variants.three electrophoretic patterns of glucose-6-phosphate dehydrogenase have been found in wild-type strains of drosophila melanogaster. genetical control of the variants in enzyme mobility (fast or slow) is x-linked; strains possessing both bands (fast and slow) appear to be heterogeneous, having individuals of three types (fast, slow, and double).196414075724
