Abstract

The functional tests in form of tolerance tests allow an insight into the adaptibility of the organism to changed inner and outer conditions. The majority of haematological functional tests demands a temporary and economic expediture which excludes it a priori as screening test. According to a previously published phase program for the haematological functional diagnosis a report is given on simple methods for judging the disturbed partial functions of the blood.

Evolutionary genomics of Culex pipiens: global and local adaptations associated with climate, life-history traits and anthropogenic factors.

We present the first genome-wide study of recent evolution in Culex pipiens species complex focusing on the genomic extent, functional targets and likely causes of global and local adaptations. We resequenced pooled samples of six populations of C. pipiens and two populations of the outgroup Culex torrentium. We used principal component analysis to systematically study differential natural selection across populations and developed a phylogenetic scanning method to analyse admixture without haplotype data. We found evidence for the prominent role of geographical distribution in shaping population structure and specifying patterns of genomic selection. Multiple adaptive events, involving genes implicated with autogeny, diapause and insecticide resistance were limited to specific populations. We estimate that about 5-20% of the genes (including several histone genes) and almost half of the annotated pathways were undergoing selective sweeps in each population. The high occurrence of sweeps in non-genic regions and in chromatin remodelling genes indicated the adaptive importance of gene expression changes. We hypothesize that global adaptive processes in the C. pipiens complex are potentially associated with South to North range expansion, requiring adjustments in chromatin conformation. Strong local signature of adaptation and emergence of hybrid bridge vectors necessitate genomic assessment of populations before specifying control agents.

Expression of Drosophila's 27 kDa heat shock protein into rodent cells confers thermal resistance.

The role of hsp27, one of Drosophila melanogaster's small heat shock proteins, in the process of thermotolerance was investigated. The coding sequence of hsp27 was subcloned downstream of the human hsp27 promoter which has been shown to be constitutively expressed in Chinese hamster O23 cells. Cellular resistance to a thermal stress was measured two days after transfection by a survival assay following a 3.5 h heat treatment at 44 degrees C. Expression of Drosophila hsp27 was shown to confer thermal resistance to O23 cells in a manner which was dependent on the level of expression of this hsp. Immunoblot analysis confirmed that the thermal resistance was related to the expression of Drosophila hsp27 as none of the endogeneous hsps showed an increased level under these conditions.

Gallium toxicity and adaptation in Pseudomonas fluorescens.

When cultured in a defined citrate medium supplemented with 1 mM gallium (III) Pseudomonas fluorescens ATCC 13525 experienced a lag phase of 40 h with no apparent diminution in cellular yield. Following initial uptake of the metal-ligand complex, gallium was secreted in the spent fluid. This lag phase was abolished either by inoculating the medium with gallium adapted cells or by inclusion of iron (III) (20 microM) in the growth medium. In the culture enriched with both gallium and iron (III), X-ray fluorescence spectra revealed a gradual decrease of gallium from the spent fluid as growth progressed. In a phosphate deficient medium, no cellular multiplication was observed in the presence of gallium. The inhibitory influence mediated by the trivalent metal was reversed by the addition of (20 microM) iron (III). Although bacterial growth was accompanied by an initial decrease in exocellular gallium, a marked increment in the concentration of this metal was observed in the spent fluid at stationary phase of growth. Citrate was not detected in the exocellular fluid at cessation of bacterial multiplication. Electrophoretic analyses revealed numerous variations in the cytoplasmic protein profiles of the control and metal stressed cells. Gallium induced the syntheses of polypeptides with apparent molecular masses of 89 kDa, 50 kDa, 39 kDa, 26 kDa and 12 kDa.
